This page reviews of all of the current models of the Sonicare electric toothbrush line.

For each toothbrush, we cover what features it has, point out how that differs from other models, and give you our opinion about the brush's collection of features as a whole, both pro and con. [If you're interested, here's the same type of breakdown for Oral-B electrics.]

As a companion piece, don't overlook reading through our Best Sonicares page, which explains what to look for and how to pick out a toothbrush that has just the features you really need.

What are the current Sonicare models?

Here's a listing of the brushes we found on the Philips Sonicare website (USA) under the category "current products" on September 5, 2017. No combination products (e.g. razor/toothbrush units) are included in this review.

Differences from our last review.
  • The DiamondClean Smart toothbrush models have been added to the Sonicare lineup since our last evaluation back in January.

    These are the new top-of-the-line brushes, both in technology and price. And as you'd expect, they feature integration with a smartphone app.

  • While no product line has been discontinued, some individual toothbrushes evidently have been. Several DiamondClean and 2 Series Plaque Control models are no longer mentioned on Sonicare's "current products" web page (USA). Although in many cases this just means that certain colors are no longer available.

Manufacturer suggested retail prices.

The toothbrushes listed on this page are ordered according to their "suggested retail price" (per information taken from the Philips Sonicare website). So as you work your way down our list, each next brush is a little cheaper than the one before it.

Prices range from around $329 all the way down to just $15. (We've included each model's MSRP price with its features list below.)

That means the price for the top-end Sonicare is now $80 more than just about a half year ago. We find that astounding, and even a little bit hard to believe. But beyond that bad news, we're happy to report that the MSRP's of all of the other models has stayed the same since our last review was completed back at the beginning of the year.

Be sure to shop around.

We've looked on the web to make certain that we could find all of the models listed above currently for sale (which we did).

In the past while doing our research we were a little bit surprised to find that some (very big name) online retailers listed a MSRP that was higher than the one shown on the Sonicare site. Of course, doing so makes it look like their price has been more heavily discounted than it really is.

We mention this simply to remind you to make sure you compare several vendor's prices before you buy.

Discounted models.

Per usual, it seemed to us that the older Sonicare toothbrush lines tended to be more heavily discounted than comparatively newer ones. Thus making them even more of a bargain.

If you want to see these models first hand ...

We've noticed a few retailers who typically have various Sonicare models, as well as other brands of electrics, on display so you can pick them up and hold them (although they're just mockups, they don't actually run). They are Walmart, Target and Bed, Bath and Beyond.

Sonicare model options and features.

How to navigate this information:
  • Jump ahead ... Throughout this page we link to other portions of our website that provide more in depth information about specific toothbrush features (such as purpose, how it works, pros/cons, etc...).

    You can either follow those links as you come to them, or else jump ahead by using one of the buttons to the right. They all lead to the same places.

  • Function vs. Value ... If you're interested in our opinion about the value of having specific features, we tend to provide more of that kind of dialogue on our "Which Sonicare models make the best buy?" page.
  • Ask a question ... If you have something on your mind that we didn't cover on our pages, you can post it as a comment and we'll try to answer it.

Features that Sonicare models tend to have in common.

Rather than describe the same set of options for each of the models below, here's a list of features that most of the toothbrushes on this page share. For those that don't, we make mention of it both here and in their respective review.

a) Full-power brushing mode.

With the exception of the PowerUp toothbrushes, all of the models on this page feature Sonicare's "31,000 brushstrokes-per-minute" brushing action. (In some Sonicare promotional materials this is referred to as the equivalent "62,000 brush movement/minute.")

Sonic toothbrushes can clean beyond where their bristles touch.

Our opinion.
  • We feel strongly that a brush must feature "31,000 brushstrokes-per-minute" capabilities.
  • We also think that this is the setting that the vast majority of owners should use. On Sonicare models this is "Clean" mode, high intensity (if the brush has intensity settings).
  • We'd be perfectly satisfied in only ever using Clean mode. And fully confident that via its use we could meet or exceed whatever might be accomplished using any of the brush's other settings.

b) Lithium-ion battery.

With the exception of the PowerUp, Essence, Essence+ and 2 Series models, the standard Sonicare rechargeable battery is a lithium ion one. PowerUp models use disposable off-the-shelf AA alkaline batteries.

Lithium ion offers some technical advantages related to recharging. Probably more noticeable to users is that the models that have them tend to have a smaller, sleeker body style. (More about batteries.)

Note: None of Sonicare's rechargeable electric toothbrushes have a design that allows for failed battery replacement. And as such, battery death generally equates with toothbrush death also.

c) 110 - 220V charging.

The chargers that come with Sonicare rechargeable brushes are designed to operate with either 110 or 220 volt power supplies, which is a point that may be important to world travelers. (More about charging units.)

d) Smartimer / KidTimer.

All of the brushes on this page feature a brushing timer of some sort. Usually it runs for 2 minutes in duration but this can vary on some models according to the brushing mode that's been selected. (More about Sonicare timers.)

e) QuadPacer / BrushPacer

QuadPacer is a quadrant timer. It signals when each 1/4th of your brushing session has elapsed, so you know when to move on to brushing the next section of your teeth. (More about QuadPacer.)

Flexcare Platinum Connected and DiamondClean Smart models have a QuadPacer-like feature referred to as BrushPacer. This references your mouth in sixths (instead of fourths) and integrates with the brush's smartphone app.

The Sonicare website and the available online user manuals don't always agree on which models have the QuadPacer. We've tended to show what the website states, assuming it is the more up-to-date information. Check the packaging of the model you are considering to be sure about what you are getting.

f) Easy-start.

This feature is an introductory mode that helps you to get used to the sensation of using your brush by gradually increasing its brushing intensity. (More about Sonicare Easy-start.)

Many, but according to Sonicare's website not all, models have this feature. It was our impression that those that didn't tended to be those that had intensity settings, which conceivably could be used as somewhat of a substitute.

Check the packaging of the specific product you are considering to know for certain if you are getting this feature or not.

g) Brushing pressure sensing.

When excessive force is used, the brushing action of Sonicare models tends to stall. Beyond that general characteristic, the Flexcare and DiamondClean Smart lines of brushes feature specific excessive brushing pressure indicators (more details about pressure indicators).

h) Click-on brush heads.

With the exception of the Essence models (not to be confused with the newer Essence+), all of the brushes mentioned on this page utilize some type of click-on (snap-on) brush head.

While there are some convenience factors associated with this design, what's more important is that this gives you a very wide range of brush head styles and sizes to choose from when selecting replacements. All click-on heads are universally interchangeable between models that use them. (The exception being the PowerUp line.)

For this reason, when selecting a toothbrush model, we place little emphasis on which types of brush heads it comes with because you'll be replacing them soon enough anyway (Philips recommends every 3 months). (More about brush heads.)


The Sonicare toothbrush lines: A review of features, by model names and numbers.

Double check brush features before you buy.

We've gone to a lot of effort in compiling this information, trying to make sure we got everything right. But beyond our control, features and options can change. And the information on websites and in promotional materials can be wrong.

Before you buy, do us a favor and just double check what we say against the packaging or description of the actual product you plan to buy. We don't want you to be disappointed.


a) The DiamondClean Smart electric toothbrushes -

This group of models is Sonicare's top-of-the-line offering.

Models:
DiamondClean Smart 9700: HX9957/51 - (MSRP $330)
DiamondClean Smart 9500: HX9924/41 - (MSRP $270)
DiamondClean Smart 9300: HX9903/41 - (MSRP $230)

( Compare DiamondClean Smart prices and deals at Walmart.com and Amazon.com. )

Differences among the members of the DiamondClean Smart line up.
  • Color options: Model 9700 - Lunar blue, Model 9500 - White, black, pink or silver, Model 9300 - White, black, pink or silver.
  • Brushing modes: The 9700 (HX9957/51) and 9500 (HX9924/41) feature 5 brushing modes (Clean, White+, Deep Clean+, Gum Health, TongueCare), and 3 intensity settings (High, Medium, Low).

    The 9300 (HX9903/41) also has the same three intensity settings to choose from but only 4 actual brushing modes (Clean, White+, Deep Clean+, Gum Health).

    Brushing routine durations: Clean = 2 minutes, White+ = 2 minutes 40 seconds, Gum Health = 3 minutes 20 seconds, DeepClean+ = 2 to 3 minutes depending on how its implemented, Tongue Care = 20 seconds.

  • Brush heads: The 9700 comes with 8 brush heads (3 C3 Premium Plaque Control, 2 G3 Premium Gum Care, 2 W3 Premium White standard and 1 TongueCare+ tongue brush).

    The 9500 comes with 4 brush heads (1 C3 Premium Plaque Control, 1 G3 Premium Gum Care, 1 W3 Premium White and 1 tongue brush).

    The 9300 comes with 3 brush heads only (1 C3 Premium Plaque Control, 1 G3 Premium Gum Care, 1 W3 Premium White).

    While having a variety of heads is nice in terms of experimentation and determining which type you prefer, brush heads are just disposable items that you'll be replacing every few months anyway (with any other kind of head you want), so this difference between models isn't all that significant.

  • Travel cases: The more expensive 9700 and 9300 models come with Sonicare's deluxe charging travel case that doubles as a charging station. The travel case that comes with the 9300 does not have the charging feature.

DiamondClean Smart features -

  • Color: See "differences" section above.
  • Top vibrational speed: 31,000 brush strokes/minute.

    Clean mode = 31,000 strokes/minute. This is Sonicare's signature brushing action and the one we feel is important to have.

  • Brushing modes: 4 or 5 total depending on model, see "differences" section above.

    Except for having Sonicare's "Clean" setting, which all of these models do, we place very little importance on a brush having any additional brushing modes. We explain our reasoning here.

  • Brushing intensities: The DiamondClean Smart brushes feature 3 intensity settings (high, medium, low). High = Sonicare's highest level of cleaning efficiency.
  • Brush heads provided: Varies per model, see "differences" section above.

    BrushSync® brush heads - Sonicare's C3 Premium Plaque Control, G3 Premium Gum Care, W3 Premium White and TongueCare+ brush heads are designed specifically for use with the DiamondClean Smart line of brushes.

    They contain a micro-chip whose presence signals the brush handle to switch to the brushing mode that Sonicare considers optimal for the use of that head, or else the mode and intensity you have programmed.

  • Replacement brush heads: The full line of Sonicare's snap-on brush heads (both those that do and don't contain the above mentioned micro-chip) fit on and can be used with the DiamondClean Smart brushes.

    Based on data from their timer and pressure sensor, DiamondClean Smart brush handles notify you with a blinking light when your current brush head should be replaced. This feature can be deactivated.

  • Easy-Start: Yes, but does not function in TongueCare+ mode. This feature can be deactivated.
  • Brush timers: BrushPacer - This is a beep and pause signal that reminds you when to move on to brushing other sections of your mouth. It also integrates with the DiamondClean Smart phone app. Its precise settings vary according to which brushing mode has been selected.
  • Smartphone app: Yes, Android and iOS. Bluetooth connectivity. (App details.)
  • Pressure sensor: Yes. - This feature signals when too much brushing pressure is detected in three ways. The brush handle will noticeably change its vibrations. A purple ring on the butt end of the brush will light up. A warning will appear on the phone app. This feature can be deactivated.
  • Scrubbing sensor: The phone app signals when too much scrubbing motion is detected in your brushing technique.
  • Charger: Each of the three models comes with Sonicare's Glass charger. With the 9700 and 9500 models, you also have the option of using the included travel case/charger.
  • Travel case: Yes, all models. - USB travel case charger. - 9700 and 9500 models only. The case requires a USB (mini) connection for charging operations.
  • Operational voltages: 110-220V
  • Battery type: Lithium ion.
  • Operating time after fully charged: "Up to" 3 weeks.

Our opinion about the DiamondClean Smart line of brushes.

This is Sonicare's top product line. And as such, there's no question in our mind that they are good toothbrushes. But beyond that we're not so sold on these models.

Probably the biggest barrier for us is simply their cost. We can barely fathom a scenario where we would consider paying more than $200 for a brush. A price of $330 just seems absurd.

Considering we only value the Sonicare "Clean" brushing mode and so very few other features, so much of what this brush has to offer is a moot point for us, or duplicated by much less expensive models.

However, if your situation is one where you want or need a brushing app, this and the Flexcare Platinum Connected are your only adult Sonicare choices.

Overall, and simply from a standpoint of value (getting the job done at the least cost), the DiamondClean Smart brushes will never have a chance of making our Best Sonicares list.

Features to keep in mind about this product line:
  • The DiamondClean Smart models are the only ones that coordinate with BrushSync brush heads. (Possibly debilitated users or those with limited dexterity would find this auto-set feature important to have.)
  • Once started, the brushing modes featured by this line run for a longer duration than those of many other models. (Generally speaking, we consider brushing for longer a good thing. However, you don't need a brushing mode to give you permission to do that.)
  • This is one of only three Sonicare lines that can be used with a brushing app.
  • Except for Clean mode, we generally consider other Sonicare brushing modes to be novelty settings. However, we can envision how having a choice of intensity level (like these brushes do) could be an asset. (Like when a frail or debilitated person needs a less aggressive brushing action.)

b) The DiamondClean electric toothbrushes -

Last year this line could have been considered to have Sonicare's top toothbrush models, although not their most sophisticated ones (they do not feature smartphone app integration).

Models:
DiamondClean HX9393/90 - (MSRP $250)
DiamondClean HX9392/05 - (MSRP $220)

Additional models you may find.

While performing research for this page's update, we noticed that Sonicare's website shows information for the following additional DiamondClean models, although they are not listed on their "current products" page: HX9372/10, HX9362/10, HX9352/10, HX9332/10.

These are all $220 MSRP brushes and from a standpoint of features are the same as the HX9392/05. We have confirmed that they are all currently available at least online.

( Compare DiamondClean prices and deals at Walmart.com and Amazon.com. )

Differences within the DiamondClean line up.
  • Each of the above models vary by way of color: HX9393/90 (black), HX9392/05 (rose gold), HX9372/10 (amethyst), HX9362/10 (pink), HX9352/10 (black), HX9332/10 (white).
  • The HX9393/90 (the most expensive model) features Sonicare's wireless charging pad and deluxe travel pouch, whereas the others come with Sonicare's glass charger and USB travel charger/case. (See below for more details about these features.)
  • The HX9393/90 comes with 2 DiamondClean (standard) and 1 AdaptiveClean brush heads whereas the other models come with 1 DiamondClean (standard), 1 AdaptiveClean and 1 InterCare (standard).

    As mentioned above, included brush heads is a non-issue to us. These are disposable items that you'll just be buying replacements for at some point anyway.

DiamondClean features -

  • Color: See "differences" section above.
  • Top vibrational speed: 31,000 brush strokes/minute.

    Just earlier this year Sonicare's promotional materials were referring to this brushing action as (the equivalent) 62,000 brush movements/minute.

    They now seem to have reverted back to the previously used 31,000 brush strokes/minute. But in our mind, it's attempts at marketing ploys like this (trying to make the same old stuff seem new and improved) that makes it hard to be willing to accept anything that Sonicare states at face value.

  • Brushing modes: 5 total - Clean, Deep Clean, Gum Care, Sensitive, White. In contrast to the DiamondClean Smart, this line does not feature brushing intensity settings.

    Clean mode = 31,000 strokes/minute. (This is the mode we feel is the most important to have, in terms of receiving maximum brushing effectiveness.)

  • Brush heads provided: Three total, see above.
  • Replacement brush heads: The full line of Sonicare universally interchangeable click-on heads can be used with these models.

    This includes: DiamondClean (standard, compact), Adaptive Clean (standard), Intercare (standard), ProResults Plaque Control (standard), ProResults Gum Health (standard), Sensitive (standard) and SimplyClean (standard), as well as the 3 BrushSync heads (standard). (More about brush head options.)

  • Brush timers: Yes, Smartimer and QuadPacer. (Quadpacer divides Smartimer's 2 minute time frame into 4ths, therefore signaling when you should switch to brushing the next quadrant of your mouth. More about Sonicare QuadPacer.)
  • Integrates with a Sonicare smartphone app: No.
  • Charging: The HX9393/90 comes with Sonicare's wireless charging pad. This unit uses the Qi standard, like that used to wirelessly recharge many smartphones.

    The other DiamondClean models come with Sonicare's glass charger. They also come with a USB travel charger case (see below).

  • Operational voltages: 110-220V
  • Travel case: Yes. - Most DiamondClean models come with Sonicare's USB travel charger case. It functions as a recharging unit so you don't have to take your "glass" one when you travel. It requires a USB (mini) port connection.

    The HX9393/90 comes with Sonicare's deluxe travel pouch. It does not have charging capabilities.

  • Battery type: Lithium ion.
  • Operating time after fully charged: "Up to" 3 weeks.

Our opinion about the DiamondClean line.

As a top Sonicare product line, there's no question that these are good brushes. But you can probably get all of the features that you really need and will use in a lesser model, for a lower price. (Figuring that out is what our Which are the best Sonicares? page is all about.)

Features to keep in mind about this product line:
  • The DiamondClean line is the only one to feature a model that comes with a wireless (Qi) charging pad.
  • We will say that if you're considering a DiamondClean model you should also consider the DiamondClean Smart 9300. They both cost about the same yet the 9300 is a more fully-featured brush.

c) The FlexCare Platinum Connected electric toothbrushes -

This, the DiamondClean Smart and the For Kids are the only Sonicare lines that integrate with a smartphone app. And this is the only line that offers the option of a UV brush head sanitizer.

Models:
FlexCare Platinum Connected HX9192/02 - (MSRP $220)
FlexCare Platinum Connected HX9192/01 - (MSRP $200)

( Compare FlexCare platinum prices and deals at Walmart.com and Amazon.com. )

Differences within the FlexCare Platinum Connected line up.

The difference between the two models offered is that the charging stand of the HX9192/02 has a UV brush head sanitizer while the HX9192/01 does not. Other than that, these brushes are the same.

FlexCare Platinum Connected features -

  • Color: White.
  • Top vibrational speed: 31,000 brush strokes/minute. (Clean mode at High intensity = 31,000 strokes/minute.)
  • Brushing modes: 3 total - Clean, Deep Clean, White. Both models also feature 3 Intensity settings: Low, medium, high.

    While we don't generally see great value in having a brush that features multiple brushing modes, the ability to change brushing intensity can be a valuable option in special cases (i.e. debilitated or elderly brush users).

    The DiamondClean Smart, HealthyWhite+, 3 Series Gum Health and For Kids models (see below) also share this capability.

  • Brush heads included: 2 total. 1 AdaptiveClean, 1 InterCare (standard).
  • Replacement brush heads: The full line of Sonicare universally interchangeable click-on heads can be used with these brushes.

    From information gathered from the brush's timer and pressure sensor, the integrated smartphone app notifies you when your current brush head should be replaced.

  • Brush timers: Yes, Smartimer and BrushPacer. (How BrushPacer differs from Quadpacer.)
  • Smartphone app: Yes, Android and iOS. Bluetooth connectivity. (App details.)
  • UV brush head sanitizer: Model HX9192/02 only. The sanitizer is incorporated into the brush's charging stand. - We don't see a great need for having this feature. We outline our argument here.
  • Charger: Traditional charging stand. A smaller travel charger separates from this unit.
  • Operational voltages: 110-220V
  • Battery type: Lithium ion.
  • Operating time after fully charged: "Up to" 2 weeks.
  • Travel case: Yes.
  • Pressure sensor: Yes. - This feature signals that too much brushing pressure has been detected in two different ways. The brush handle gently pulsates to alert the user. The phone app shows a warning on its screen.
  • Scrubbing sensor: The phone app signals when too much scrubbing motion is detected in your brushing technique.

Our opinion about the FlexCare Platinum Connected line.

If you're looking for a brush that offers pretty much all of Sonicare's available bells and whistles, then this line may be the one for you.

However, our opinion would be that while we can see how any or all of this line's features and functions might appeal to some people, for the person who just needs a good electric toothbrush there are other equally capable, less expensive choices.

Features to keep in mind about this product line:
  • The FlexCare Platinum Connected and the DiamondClean Smart are the only two "adult" brushes that integrate with a Sonicare smartphone brushing app.
  • This line and the DiamondClean Smart are the only ones to feature pressure and scrubbing sensors.
  • The FlexCare HX9192/02 is the only Sonicare brush that has a UV brush head sanitizer.
  • While we feel that Clean mode on its own almost always makes the best brushing choice, we can see how having the option of intensity settings (a feature this line has) might be beneficial in some situations.

d) The FlexCare+ electric toothbrushes -

This is one of of Sonicare's high-end brushes from yesteryear.

Models:
FlexCare+ HX6921/04 - (MSRP $150)

( Compare FlexCare+ prices and deals at Walmart.com and Amazon.com. )

FlexCare+ features -

  • Color: Cooper Frost (white)
  • Top vibrational speed: 31,000 brush strokes/minute.
  • Brushing modes: 5 total - Clean, Gum Care, Refresh, Sensitive, Massage. (Clean mode = 31,000 brushstrokes-per-minute.) As compared to the Flexcare Platinum Connected, this line does not feature brushing intensity settings.
  • Brush head provided: One total. ProResults Gum Health.
  • Replacement brush heads: The full line of Sonicare universally interchangeable click-on heads can be used with this brush.
  • Smartimer and QuadPacer: Yes. (Quadpacer can be deactivated on this model.)
  • Integrates with a Sonicare smartphone app: No.
  • Charger: Traditional charging stand. A smaller travel charger separates from this unit.
  • Operational voltages: 110-220V
  • Battery type: Lithium ion.
  • Operating time after fully charged: "Up to" 3 weeks.
  • Travel case: Yes.
  • Pressure sensor: Yes. The brush handle gently pulsates when too much brushing pressure is detected. (In general, we don't see a big need for this feature. We explain why here.)

Our opinion about the FlexCare+ line.

Except for the ability to deactivate the QuadPacer (which evidently is an annoyance for some people), there's nothing especially noteworthy about this brush. Cheaper alternatives exist.

Features to keep in mind about this product line:
  • This is one of only three Sonicare lines that features a true excessive brushing pressure indicator.
  • This and the HealthWhite+ are the only models we're aware of that allows you to deactivate the QuadPacer function.

e) The HealthyWhite+ electric toothbrushes -

It's our impression that this toothbrush sits on the boundary between Sonicare's higher and lower-end lines.

Models:
HealthyWhite+ HX8918/10 - (MSRP $130)
HealthyWhite+ HX8911/02 - (MSRP $120)

( Compare HealthyWhite+ prices and deals at Walmart.com and Amazon.com. )

Differences within the HealthyWhite+ line up.

These models only vary by way of the fact that the HX8918/10 comes with an additional tongue cleaner brush head (TongueCare+, HX8072/80), along with a small bottle of antibacterial tongue spray (DIS359/03).

Keep in mind that these same items can be bought separately and used with any other Sonicare model that uses click-on heads. Also, there are other (possibly more effective and cheaper) ways to clean your tongue. We discuss them here.

Picture of a Sonicare HealthyWhite+ sonic toothbrush.

Sonicare Healthy White+ HX8911/02

HealthyWhite+ features -

  • Color: Frost White
  • Top vibrational speed: 31,000 brush strokes/minute.
  • Brushing modes: 2 total - Clean, White. 3 brushing intensity settings are also featured: High, medium, low. (Clean mode at High intensity = 31,000 brush strokes/minute.)
  • Brush head provided: One DiamondClean (Standard).
  • Replacement brush heads: The full line of Sonicare universally interchangeable click-on heads can be used with this brush.
  • Smartimer and QuadPacer: Yes. (Quadpacer can be deactivated on this model.)
  • Integrates with a Sonicare smartphone app: No.
  • Charger: Conventional charging stand.
  • Operational voltages: 110-220V
  • Battery type: Lithium ion.
  • Operating time after fully charged: "Up to" 3 weeks.
  • Travel case: Yes.

Our opinion about the HealthWhite+ line.

As you descend down this page, this brush seems to us to be the last of the higher-end, as opposed to budget-oriented, Sonicares and therefore a reasonable choice for those looking for a comparatively better-quality product.

Features to keep in mind about this product line:
  • This is one of the Sonicare lines that features switchable brushing intensities.
  • These models allow QuadPacer to be turned off.

About the rest of the toothbrush lines on this page.

With the exception of the For Kids, the models below this point should probably be considered to be Sonicare's economy brushes.

To their credit, all but the PowerUps still feature Sonicare's all-important 31,000 brush-strokes-per-minute brushing action. But as lower-cost alternatives their mechanisms aren't as refined (smooth) or powerful as the models above.

There seems to be two classes of economy brushes. Those that are simply older technology (Essence, Essence+) and those that seem to have been designed as cheap Sonicares just to fill a price point (3 Series, 2 Series, PowerUp).

It would be our impression from reading online comments and user reviews that with the latter group build quality is sometimes an issue. We reflect on these concerns on our How to pick out the best Sonicare value page where these individual models are discussed.


f) 3 Series Gum Health electric toothbrushes -

Models:
3 Series Gum Health HX6631/02 - (MSRP $90)

( Compare 3 Series prices and deals at Walmart.com and Amazon.com. )

3 Series Gum Health features -

Picture of a Sonicare 3 Series sonic toothbrush.

Sonicare 3 Series HX6631/02

  • Color: Persian Green.
  • Top vibrational speed: 31,000 brush strokes/minute.
  • Brushing modes: 1 total - Clean. It also has 3 brushing intensity settings: High, medium, low. (Clean mode at High intensity = 31,000 brushstrokes-per-minute.)
  • Brush head provided: One ProResults Gum Health.
  • Replacement brush heads: The full line of Sonicare universally interchangeable click-on heads can be used with this brush.
  • Smartimer and QuadPacer: Yes.
  • Integrates with a Sonicare smartphone app: No.
  • Charger: Conventional charging stand.
  • Operational voltages: 110-220V
  • Battery type: Lithium ion.
  • Operating time after fully charged: "Up to" 3 weeks.
  • Travel case: Yes.

Our opinion about the 3 Series Gum Health line.

This model (along with its price) seems to be an attempt to meld Sonicare higher and lower-end models. (For example, it just has one brushing mode but features a lithium ion battery.)

Its only brushing mode is the one we think is the most important to have ("Clean"). And it has intensity settings to boot (for those who have an application where a lower-intensity setting is needed).

However, from reading comments on both our and retailer websites, it seems that some people who have owned higher-end Sonicares before consider this to be an lesser product in terms of power and mechanism refinement.

Features to keep in mind about this product line:
  • This brush is one of the Sonicares that offers the option of using different brushing intensities.

g) The 2 Series Plaque Control electric toothbrushes -

Models:
2 Series Plaque Control HX6218/10 - (MSRP $80)
2 Series Plaque Control HX6211/07 - (MSRP $70)

( Compare 2 Series prices and deals at Walmart.com and Amazon.com. )

Differences within the 2 Series line up.
  • These models vary by way of their colors: HX6211/07 (black with white highlights), HX6218/10 (white with blue highlights)
  • The HX6218/10 comes with a tongue cleaner brush head (TongueCare+, HX8072/80), along with a small bottle of antibacterial tongue spray (DIS359/03). (As mentioned and linked to above, there are probably more effective ways to clean your tongue.)

2 Series Plaque Control features -

Sonicare 2 Series HX6211/04

  • Color: See above.
  • Top vibrational speed: 31,000 brush strokes/minute.
  • Brushing modes: 1 total - Clean. (Clean mode = 31,000 brushstrokes-per-minute.)
  • Brush head provided: One ProResults Plaque Control.
  • Replacement brush heads: The full line of Sonicare universally interchangeable click-on heads can be used with this brush.
  • Smartimer and QuadPacer: Smartimer only.
  • Integrates with a Sonicare smartphone app: No.
  • Charger: Conventional charging stand.
  • Operational voltages: 110-220V
  • Battery type: NiMH. - This is the slightly less advantageous style of battery. Also, notice a lower operating time of two weeks (vs. three for the 3 Series).
  • Operating time after fully charged: "Up to" 2 weeks.
  • Travel case: No.

Our opinion about the 2 Series Plaque Control line.

Like the 3 Series, the 2 Series models probably have all of the brushing options you really need. But there are some differences:

  • It only features a NiMH battery (see above).
  • It doesn't have the 3's ability to change brushing intensity. But if your application doesn't involve special cases (elderly or debilitated brush users), you probably have no use for this option.
  • Does not have the QuadPacer feature.

As discussed with the 3 Series above, some commenters on our and retailer websites have mentioned their concerns about this brush (power, build quality) as compared to Sonicares they have owned before.

Sonicare For Kids HX6321/02

  • Color: Aqua, with 8 different "jazzy" stickers you can apply.
  • Top vibrational speed: 31,000 brush strokes/minute.
  • Brushing modes: This brush features 2 settings: High and low. The lower setting is intended for use by smaller, younger children. (The High setting = 31,000 brushstrokes-per-minute.)
  • Brush head provided: One Sonicare for Kids (Standard).
  • Replacement brush heads: The full line of Sonicare universally interchangeable click-on heads can be used with these models.

    For-Kids brush heads come in both Standard and Compact sizes and feature softer bristles than the adult ones. The Compact heads are intended for use with smaller, younger children.

  • Smartimer and QuadPacer: Yes, however with this brush these features are referred to as KidTimer and KidPacer.

    (If you're an adult and are considering using this brush yourself, you must read this section that describes how these functions work.)

  • Smartphone app: Yes. (For Kids app, see below.)
  • Charger: Conventional charging stand.
  • Operational voltages: 110-220V
  • Battery type: Lithium ion.
  • Operating time after fully charged: "Up to" 2 weeks.

The For Kids Smartphone brushing app.

Via Bluetooth connectivity, this brush can communicate with an app installed on your smartphone (free - iOS and Android).

The app tracks each brushing session and its duration, gives brushing tips and provides games that can help to increase brushing motivation.

Our opinion about the Sonicare For Kids line.

This model makes a good choice for children, or a reasonable one for families that would like to share a single brush. It can also make an acceptable budget choice for an adult (if you don't mind using a toothbrush that's designed for children).

Features to keep in mind about this product line:
  • This brush offers two brushing intensities.
  • Just like with "adult" models, the For Kids can use the full range of Sonicare click-on brush heads.

i) The Essence+ electric toothbrushes -

Models:
Essence+ HX3211/17, HX3211/02, HX3211/33 - (MSRP $40)

( Compare Essence+ prices and deals at Walmart.com and Amazon.com. )

Differences within the Essence+ line up.
  • These are all basically white toothbrushes but the color of their trim varies: HX3211/02 (light blue), HX3211/17 (mid-blue), HX3211/33 (dark blue).
  • Each comes with a different style of brush head: HX3211/02 - Sensitive (standard), HX3211/17 - SimplyClean (standard), HX3211/33 - ProResults gum health.

Essence+ features -

  • Color: White with blue rubber grips. (Either light blue, mid-blue or dark blue depending on model, see above.)
  • Top vibrational speed: 31,000 brush strokes/minute.
  • Brushing modes: 1 total - Clean. (Clean mode = 31,000 brushstrokes-per-minute.)
  • Brush head provided: One brush head - Either Sensitive (standard), SimplyClean (standard) or ProResults gum health depending on model (see above).

    Note: This brush has a snap-on brush head design that means it can be used with the full line of Sonicare universally interchangeable click-on heads. That's a nice advantage over the regular Essence model (discussed next).

  • Smartimer and QuadPacer: Yes.
  • Integrates with a Sonicare smartphone app: No.
  • Charger: Conventional charging stand, similar in design to more modern Sonicares.
  • Operational voltages: 110-220V
  • Battery type: NiMH. - The non-lithium ion battery option.
  • Operating time after fully charged: "Up to" 10 days.

    Note: In comparison, the specs for the standard Essence say "up to 2 weeks."

  • Travel case: No.

Our opinion about the Essence+ line.

Even though this brush seems to be the old (ancient) Essence design, just with a modern click-on brush head placed on it, it still makes a perfectly reasonable choice. (Because it has "Clean" mode and a 31,000 brush-strokes-per-minute brushing action.)

However, it must be said that as compared to all of the more modern brushes above, this unit is a bit larger, heavier, louder and its handle vibrates more. It may not make the right choice for debilitated or elderly users.

j) The Essence electric toothbrushes -

Models:
Essence HX5611/01 - (MSRP $25)

( Compare Essence prices and deals at Walmart.com and Amazon.com. )

Essence features -

  • Color: White with blue rubber grips.
  • Top vibrational speed: 31,000 brush strokes/minute.
  • Brushing modes: 1 total - Clean. (Clean mode = 31,000 brushstrokes-per-minute.)
  • Brush head provided: One e-Series (Standard). - This is the older screw-on type head.
  • Replacement brush heads: Only e-Series brush heads can be used with the Essence. That means you have a much more limited choice than with other models, however they do come in both Standard and Compact sizes.

    (Possibly e-Series heads are less efficient brushers than other styles. This page provides more information.)

  • Smartimer and QuadPacer: Smartimer only.
  • Integrates with a Sonicare smartphone app: No.
  • Charger: Conventional charging stand.
  • Operational voltages: 110-220V
  • Battery type: NiMH. - The non-lithium ion battery option.
  • Operating time after fully charged: "Up to" 2 weeks.
  • Travel case: No.

Our opinion about the Essence line.

For anyone who has used Sonicare toothbrushes over the years, you'll recognize this model as "newer" old-style technology. It's a decent brush, just dated.

  • It should be mentioned that this unit is a bit larger, heavier, louder and vibrates more so than the newer Sonicare designs, so it may not be the right choice for elderly or debilitated brushers.
  • It uses the less convenient (and less diverse in available designs) e-Series style brush heads.

k) The PowerUp electric toothbrushes -

Models:
PowerUp HX3631/06, HX3631/10 - (MSRP $15)

( Compare PowerUp prices and deals at Walmart.com and Amazon.com. )

Differences within the PowerUp line up.
  • The HX3631/06 is White/Scuba Blue in color and comes with a Medium PowerUp brush head.
  • The HX3631/10 is White/Pink in color and comes with a Soft PowerUp brush head.

PowerUp features -

  • Color: See above.
  • Top vibrational speed: 15,000 brush strokes/minute.
  • Brushing modes: 1 total - Clean. - IMPORTANT: Clean mode = 15,000 strokes-per-minute. That's 1/2 the speed of the other models on this page.

    There can be applications where a low-power brush is desirable (use with elderly or debilitated persons who can't handle full-power mode). But if you're looking to buy a Sonicare because of its exceptional cleaning ability, these models don't make the right choice.

    Having said that, as compared to other low-end toothbrush brands, the PowerUp probably makes a reasonable choice.

  • Brush head provided: One PowerUp (soft or medium, see above).
  • Replacement brush heads: Only PowerUp brush heads can be used with these brushes. Two styles are available, Medium and Soft.
  • Smartimer and QuadPacer: Smartimer only.
  • Integrates with a Sonicare smartphone app: No.
  • Battery type: Powered by 2 AA alkaline disposable batteries. - This is the only Sonicare on this page that has replaceable batteries. Depending upon your application, you may find this to be an advantage.
  • Operating time on fresh batteries: 120 two-minute brushings.
  • Travel case: No.

Our opinion about the PowerUp line.

For the vast majority of users, any other brush on this page would make a more effective brushing choice than a PowerUp (due to this brush's low-speed brushing action).

Features to keep in mind about this product line:
  • This is the only Sonicare electric that uses replaceable, off-the-shelf batteries. (That can be a convenience for travelers.)

Still need help in deciding?

If you've read through everything we've said above and you still don't know which model suits you best, read this page that explains how to sort these models out.

Is Sonicare really that good?

My Sonicare just died. It was a good brush except for the fact that it didn't last very long. Do other people complain about this? I'm looking at these prices and wondering if it's really worth it.

Did you call Sonicare?

Reliability is a hard thing to judge. We consider Sonicare and Oral B to be reputable manufacturers but don't have any hard statistics to back that up.

We've read some pretty interesting user reviews where Sonicare owners called the company and told them their complaints (evidently politely). And as a result had their broken units unexpectedly replaced, evidently for free. It's worth a try. It seems if the customer has a legitimate complaint that Sonicare listens (at least sometimes).

If you want to consider an Oral-B instead, we have a whole section on them that could help you get started picking one out.
Good luck. Report back if you don't mind.

they all die pretty fast

2 of my Philips brushes died after 1.5 years of use. Water gets inside them....

POOR Quility POOR company service

We have owned many sonicare toothbrushes in the past. All USED to be a very good product. I think they have tighten their belt and outsourced to the CHEAPEST manufacturer possible. Being a dental professional we USED to buy these in numbers and use as giveaways/promotional to patients. This is NO LONGER the case. They are a piece of junk now. Had problems with the "new" brush head falling off. I was basically told your problem.. NO, not my problem any longer. I attend many dental meeting with other dentist. I have been a one man wrecking crew telling my story.. I WONT EVER recommend the Phillips Sonicare to ANYONE again. I hope you will boycott this product too.

Thank you!

I have been using the Sonicare Essence for many years now. My first one lasted about 8 years before it finally stopped holding a charge. Got a new one and it died within warranty so they replaced it, no charge to me, with the same model but it had the quad pacer, which my broken one did not have. It's still working fine after 3 years but I am looking at getting the Series 3 as I was told my gums are getting "soft". I had been looking at the more expensive models but thanks to your information I see I'd be paying for things I wouldn't really be needing or using. Thanks for saving me some $$ that will be put towards dental visits for replacing ancient fillings! I appreciate all the information I found here-thank you!

Thanks for posting Laura.

Thanks for posting Laura. Thanks for mentioning your experience with Sonicare and how their replacement policy worked out for you.

Your information couldn't

Your information couldn't have been more helpful. Terrific research. Saved me $110 !!!
Thanks so much!!

This site is a gem

My wife had an ancient Essence type Sonicare brush which she wanted to replace. In checking the current Sonicare product line we were baffled by all the various Sonicare models, brush heads and features. Then your wonderful web site came to the rescue, cleared away all the verbiage and made it crystal clear what characteristics are the important ones. As a result my wife bought a simple Series 2 brush on sale which we are sure will suit her needs. Thanks for your help!

Holder for the brush heads

The older screw on brush head models included a holder that allows you to store two brush heads in the upright position. Other than the UV models, do any of the newer click on Sonicare models include a similar brush head holder? If not, how are you supposed to store them between brushings?

Roxanne

You'll need to look closely at the packaging of the products you are comparing.
The charging bases of some Sonicare models have an extra numb (one, possibly two) sticking up that you can store extra brush heads on.
We see storage nubs on the Flexcare models as well as some of the HealthyWhites.
The DiamondClean, since it features the "glass" charger doesn't offer this feature.
We don't believe you'll find it on the lower-end Sonicares either but to be sure you'll simply have to look.

HX6211 is US only

The HX6211 model seems to be US only. The nearest I can find in the EU is the HX6231, which seems to come with Quadpacer. Philips, what a bunch of idiots - make a great brush and then annoy the hell out of everyone with two annoying features which I am putting some serious effort into trying to *avoid*.

Private

Look for a FlexCare model in your country. Then Google around for its user manual. Check to see if with this line you can't deactivate the QuadPacer. (You should be able to on the FlexCare+ and FlexCare Platinum Connected)

Healthywhite+ Quadpacer can be deactivated

I just got a Healthywhite+ from Amazon and I wanted to let you know that the Quadpacer can be deactivated by pressing and holding the intensity level down button while it's on the charger. Thanks for all the good information on this site!

Thanks SL,

We've confirmed what you report and have edited our pages accordingly.

Pink toothbrush

Bought on 6-3-17 and no longer holds a charge; 7-7-17. Replace it or do so buy a new one? Thanks.

Judi

One of the premises of this page is that in a era of lowest-cost manufacturing, getting the cheapest model that serves your needs (the main subject of this page) may be your best overall protection.

HX6970 versus HX6960

Has anyone noticed or is it factual that the HX6970 black Philips is more powerful than HX6960? I was sent a replacement for one of my Black HX6970 handles (two in the set with charger from Costco) The white replacement HX6960 seems far less powerful. I was thinking of sending it back and asking for a replacement of my exact model if there is a power difference . Is it just me or is there an actual difference in power? It seems to be not as intense of brushing on the identical "clean" setting and the other settings are worthless and it's missing the max and go care.

VLC

The model numbers HX6970 and HX6960 don't appear in the current line up of Sonicares on their official site but generally speaking the HX69 portion of a number typically indicates a FlexCare+ model. That's a relatively higher-end Sonicare. At one time it was the top of the line model.

Model numbers that close together (70 vs. 60) typically does just indicate a very minor difference, such as color. It would be our expectation (unless you noticed something on the packaging that indicated differently) that the two brushes would be pretty much identical mechanically.

We wonder if the replacement brush you received is a "refurbished" one, and while mechanically functional not truely up to snuff.

Excellent

Your site provided excellent information on the various (way too many) models available. Using your review I think I made a good choice while replacing four old Sonic models - and you saved me money too. Thank you!

AA Battery powered model discontinued

The original battery powered unit I have using AA batteries cleans at 31,000 strokes. I can't seem to find a replacement. What happened? This power up model is sluggish and doesn't seem to do as good a job at cleaning. Why doesn't Sonicare produce the better quality AA battery powered model any longer? When trveling the charging model is toast.

JT

We remember the Sonicare Xtreme, and like you suggest, since it used off-the-shelf AA batteries a fresh charge was always possible, no matter where your were.

We assume you've read what we state about the PowerUp above (it's a 15,000 brush not a 31,000 one) and how we don't think it makes an acceptable choice.

The rechargeable Sonicares that would be better at sustaining a charge are the lithium ion battery models. We show "operating time" estimates above.

Are the New Models Weak?

It was finally time to retire my original Sonicare. I think its an A-Series (I cut it open and replaced the batteries). I got an Essence+ and Adaptive Clean brush heads. It was very underwhelming, the old Sonicare feels like a jack-hammer compared to the new one.

Its fully charged and the easy start is turned off. I tried the brush head supplied with the Essence+ and it feels a little stronger but still not as good as the old.

I tried placing the old and new in a bowl of water and turning them on. There is absolutely no comparison.

Did I happen to get a dud or are they really just weaker?

Thanks!

Rob

Sonicare's trend ever since the Elite replaced the A-series has been toward smaller, lighter brush heads, which require a less powerful motor to create their brushing action.

In fact, we ran across a web page that described rigging Elite heads to work on A-series handles. And it describes how much more powerfully that smaller head is driven when that is done. So the reduction in power (level of agitation) is by design, and should not necessarily be confused with the brush's inability to clean effectively (plaque is a soft substance and harsh scrubbing isn't required to remove it).

As side from that, and as we describe elsewhere on our pages, higher-end Sonicare products tend to have "stronger" motors. A difference that is most noticed by previous Sonicare owners when buying economy models.

Yup, I have been using E

Yup, I have been using E-Series brushes on the old handle. I'll read through the pages again to see how much I have to spend for a stronger one. I called Sonicare and was told they all have the same power but the customer service agent probably was confusing power with frequency.

I have some small accelerometers and am tempted to actually measure the difference between the old and Essence+ and the one I try next. But like you said, it only need to be strong enough to do the job.

Thanks

Rob

Rob

After you go through your investigation please post again.

We're not so sure your expectation of the experience of an e-series head running on an a-series handle is a realistic one. That was never a configuration Sonicare intended (sold as a toothbrush unit).

Generally speaking, the Healthywhite+ seems to us to be the low end of the more powerful Sonicares. Although most people seem to notice a difference in power between that level of brush and the DiamondClean (for example). It just gets to a point where you have to decide how much you are going to spend on one of these devices.

It is the brush frequency that has to do with the brush's "sonic" cleaning abilities (cleaning beyond where the bristles touch). We're convinced enough that in the sense of just letting the brush run as you gently work it around, all of these brushes can be effective cleaners despite their differences in "power."

While we rather imagine you know, you should be able to return your Essence+ to Sonicare for a refund.

I made some relative

I made some relative measurement between the hand pieces and brushes. An accelerometer was located mid brush-head behind the brush. These are no-load measurements (other than the mass of the accelerometer and mounting block) so they do not simulate brushing pressure. They also don't assess the different bristle designs.

Essence+ = 0 dB (set as baseline), fundamental frequency = 270 Hz (32,400 strokes / min)
Original handle with currently available brush head = +5 dB (1.9 times stronger), Fundamental = 260 Hz (31,200 strokes / min)
Original handle with original A-Series brush head = +7.3 dB (2.5 stronger than Essence+), Fundamental = 260 Hz (31,200 strokes / min)
HealthyWhite+ = +10 dB (3.2 times stronger than Essence+), Fundamental = 260 Hz (31,200 strokes / min)

Notes:
- A-series brush total length is shorter than current brushes.
- HealthyWhite only examined at full power
- Harmonic content not quantified but it appeared similar between configurations

My guess is the Essence+ that I had was defective and not necessarily designed to be that weak. The slight frequency shift might also be indicative of an issue.

If I was doing this "for real" the brush would have been modified (sanded flat, tri-axial accelerometers epoxy mounted) and a simulated brush force applied. Would be interesting to measure the signal transmitted through the bristles to a simulated tooth!

I've been using the HealthyWhite+ for about a week. The AdaptiveClean brush head feels significantly stronger than the SimplyClean brush, buts its big. With a manual toothbrush I like smaller brush heads but it doesn't seem to be a problem with it on the Sonicare. I have not yet tried the DiamondClean brush that came with the HealthyWhite+.

Thanks for taking the time to

Thanks for taking the time to experiment and post (Rob?).

It'd be appreciated if you could help with some clarification.

You compared:
Essence+
An old A-series brush handle with an A-series brush head.
An old A-series brush handle substituting an e-series brush head.
HealthlyWhite+

When running, the Essence+ vibrated at 270hz, all of the others at 260hz (the 31,000 strokes per minute that Sonicare usually states).

Beyond that, your decibels number is a measure of power ... and you found the HealthWhite+ to be the most powerful (stronger) of the lot? You also found that in the case of the A-series brush handle that it with the original A-series brush head made a more powerful combination than it with the e-Series (a smaller, lighter brush head).

You also make mention of a subjective comparison of the Adaptive Clean vs. Simply Clean brush heads when mounted on the HealthyWhite. What you have noticed seems to correlate with the grading scale that Sonicare assigns to their brush head lineup.

Thanks again for posting your information. Please point out my errors in interpreting what you have posted if needed.

You got it!

You got it!

I was measuring acceleration which is related to velocity, displacement, and power. When you turn up the volume on your stereo, the speaker cone vibrates at the same frequency but it moves a greater distance so its acceleration and speed also increase.

Thanks again Rob.

Thanks again Rob.

Diamond clean

Had a Essence for years....loved it. When it died I bought Diamond Clean. What a piece of crap. Does not charge well. I get one brushing between charges. Travel with it? No way. I would never ever under any circumstances recommend this product. I would give it 0 stars as a rating.

Thank you for this very informative website. I appreciate the info very much.

Wes,

Thank you for posting.

At times Sonicare customer service can be accommodating. You should call them with your complaint to see if they will offer you a replacement. Their stats say that that model should hold a charge for "up to 3 weeks." Let them know what's going on and see if they'll offer a solution.
