The 3 BIG questions about the Sonicare EasyClean

If you are short of time, the answers to the following 3 questions should let you know all you need to about the EasyClean HX6511/51. If I have missed something, let me know in the comments.

If you want more detail, you can read my full Philips Sonicare EasyClean HX6511 review further down the page.

1. Is there anything drastically wrong with this toothbrush?

No, there really isn’t.

It cleans the teeth really well, it has a 2 minute timer and pacer built-in and has a great battery life. There is little to fault here.

2. Which other brushes should I consider?

As good as the EasyClean is, you should really consider the ProtectiveClean 4100 from Sonicare.

It has similar features and cleans the teeth very well. It does have a more innovative system to remind you when to change your brush head and it also comes in a number of different colors.

The 4100 is just a bit more modern and costs about the same, if not a bit cheaper.

You could also consider the Oral-B Pro 1000, which is similarly priced with a good clean. The battery life is not quite as good though.

3. Where is the best place to buy the EasyClean from Sonicare?

Although generally Sonicare toothbrushes are stocked by a wide range of retailers, the EasyClean is one of the few models that are not sold by the majority.

BestBuy and Walmart are typically the better stockists of this model, however you can potentially purchase from Target and Amazon too.

Pro & Cons

Here are what I consider to be the pros and cons of the HX6511/51 EasyClean toothbrush.

The Positives

  • 1 cleaning mode – Nice and simple, just 1 mode that offers a fantastic clean, no additional modes to complicate the offering.
  • Long battery life – Although advertised with 2 weeks battery life, it has managed to achieve 3 weeks or 84 minutes of brushing time.
  • Built-in timer – A 2 minute timer and 30 second pacer helps keep you brushing the teeth evenly and for the dentist recommended time.

The Negatives

  • No travel case – No travel case is provided in the box with the EasyClean HX6511, whilst not essential, would have been nice.
  • Clinical design – Very clinical and clean looking design, not the most engaging.
  • Better value options – For the price asked of it, there are better value options available.

Design, usability, clean & general use

The EasyClean HX6511 is a rather clinical looking brush, there is little in the way of unique design cues or colors to really catch your eye.

Some may argue that this is fine of a toothbrush, but I would personally like to see a little more personality in a brush.

The gloss white plastic body that houses the internal workings of this electric brush is almost perfectly cylindrical.

Philips Sonicare EasyClean Review 2

On the front is a mint green colored power button, positioned just above halfway up the body.

The soft rubber button has a raised power icon on it which not only signifies that it is the power button but offers a little grip when using with wet hands.

Philips Sonicare EasyClean Review 3

Contoured into the body of the brush, it provides good feedback when pressed and is not too stiff, so even those with small hands or limited movement will find this ok to use.

Within the power button, itself is an LED indicator light that illuminates when in use to feedback the battery power.

Philips Sonicare EasyClean Review 4

It is on the back of the brush that we find a series of ridges on the plastic body that offers up additional grip to hold the brush firmly in the hand.

The EasyClean HX6511 offers only 1 cleaning mode and that is the common ‘Clean’ mode designed for the everyday user.

Some may wish for more modes, but the 1 mode serves the majority just fine and does a fantastic job at cleaning the teeth and gums, when used correctly.

Once powered on the clean mode lasts for 2 minutes in total or 120 seconds.

The sonic cleaning action that the brush offers delivers 31,000 strokes/62,000 movements per minute to the bristles on the brush head.

As the brush is turned on, it activates the timer and quadpacer that are built-in.  

At 30, 60 and 90 seconds the quadpacer will pause the brush motor which in turn provides a pause/change in the brushing sensation as well as the sound to indicate to you that it is time to move to another quadrant of the mouth.

Spending 30 seconds on each of the 4 sections of the mouth will allow you to get a good clean of the teeth and gums.

At the end of the 2 minute cycle the brush will automatically switch itself off so you do not have to and ultimately indicates that the recommended 2 minute clean is complete.

If you wish to use it for longer, you will have to switch the brush back on again.

When in use the brush is very quiet and there is just a high pitched humming sound that comes from it.

Philips Sonicare EasyClean Review 6

A nice touch with this brush is that out of the box, the brush does not initially begin working at full power.  An ‘Easy-start’ mode is enabled which means that over the first week’s usage or first 14 cleans, the brush intelligently increased the amount of power and number of strokes the brush head completes.

This mode is designed to ease you and your teeth and gums into the increased power and efficiency offered by an electric toothbrush compared to a manual one.

Some will find this very handy, others not so.  It can be turned off, through a precise process explained in the manual.

Included in the box is just one brush head, the C1 ProResults brush head.

The head provides a good overall clean, but is just one of a wide range of interchangeable and compatible brush heads that could be used with this toothbrush.

Any brush head from Sonicare should be changed every 3 months to ensure you are protecting your teeth and gums whilst getting maximum cleaning performance.

There is no pressure sensor built into this toothbrush, so if you do brush with too much force, you are not alerted, just remember the bristles really need only skim the tooth surface.

A nice addition would have been a travel case, but it is not all that surprising it is excluded. If you do travel frequently, you may want to pick up a case to protect the handle and head or consider a different toothbrush.

Summary of design, usability, clean & general use

  • Clinical looking brush
  • Slim and comfortable to hold
  • All white with a mint green power button
  • LED indicator on the power button for battery status feedback
  • Ridges on the rear for grip
  • 1 cleaning mode
  • Built-in quadpacer and 2 minute timer
  • Automatic power off
  • Quiet brush with a high pitched humming sound
  • EasyStart feature which increased brushing power over 14 days
  • Interchangeable brush heads
  • No pressure sensor
  • No travel case

Battery life

In my opinion, a toothbrush with a built-in rechargeable battery should last at least 2 weeks. This allows most to go on a vacation, not needing to worry about whether to take a charger or not.

The EasyClean is advertised as being capable of achieving this.

However, in my hands-on testing it actually performed even better and makes the competition (Oral-B) look pretty weak.

Philips Sonicare EasyClean Review 7

Based on one user, the EasyClean will last for 42 x 2 minute cleans, which is 84 minutes of brushing time or 3 weeks usage.

Part of why the brush is so efficient is that at the end of a 2 minute cleaning cycle it automatically powers off.

It is a simple feature which not only conserves power but saves a button press for the user and is a great indicator that brushing time is complete.

The brushing is less noisy than an Oral-B brush, so it seems that the Philips motor is more efficient in its power use.

For those that are wondering, it is a Lithium-Ion battery that the EasyClean uses, not Nickel Metal Hydride (NiMH) and the battery is not user removable. Trying to remove it may cause the brush to stop working and will invalidate the warranty.

Included in the box is a charging station.  

It supports 110-220v which means you can take it with you on an international trip and need only carry a plug adapter and not a voltage adapter. Howver, with a 3 week battery life taking the charging stand is likely not necessary.

Philips Sonicare EasyClean Review 8

It comes with a 2 pin plug for US sockets and you get about 4 foot of cable on the stand.

The brush can potentially take up to 24 hours to charge fully, but you can take it off the stand sooner if required. It is also perfectly fine to leave the toothbrush on the stand all the time when not in use.

When you are using the brush, you will get feedback about the battery status via the LED built-into the power button on the brush handle. This is very useful.

The color of the LED will change to reflect the remaining power.

A solid green light indicated 50-100% power remaining, whilst a flashing green light suggests 5-49% remaining. A flashing green light and 3 beeps after the brushing cycle means that there is less than 5% remaining and toothbrush has to be recharged

Summary of battery life

  • Claimed 2 weeks of battery life
  • Capable of 84 minutes of usage time or 3 weeks usage based on 2 cleans a day
  • 110-220v charging stand included in the box
  • Can take up to 24 hours to charge the battery fully
  • Can be left sitting on the charging stand
  • LED on the power button gives feedback of the battery charge levels

Price & where to buy

I have included links to buying options here at the start of the review.

In the section below, I discuss the price more generally and in relation to similar products.

The EasyClean has a very fair recommended retail price of $49.97.

Honestly, I do think the HX6511/51 does, for the most part, justify this price tag.

However, there are some other toothbrushes that put up a good fight at similar prices.

Adding to the complexity of the decision is the knowledge that it is not uncommon for the typical selling price to be a few percentage points below what is recommended. Discounts can be as great at 20%.

At the time of review, the average price is around $45, approx 10% less than retail.

For this price, I really do not think you are getting a bad brush, nor would I suggest you have paid over the odds or being ripped off.

But, there are other products, including the ProtectiveClean 4100 from Sonicare that are similarly priced.

Philips Sonicare EasyClean Review 9

The 4100 actually has a higher retail price, but the typical selling price is basically the same, if not slightly lower than the EasyClean.

Cleaning performance is the same, the battery life is better on the 4100 and also working in favor of the ProtectiveClean are the handle color choices and the technology built-in that reminds you to replace the brush head.

Here at Electric Teeth, to give a bit of a benchmark, we work out the cost of ownership over a 3 year period. This includes replacement brush heads that are required every 3 months.

Factoring in the cost of the toothbrush handle and the required replacement brush heads, you are looking at a total cost of $133 or $0.12 per day.

The ProtectiveClean from Sonicare is around $0.13 or possibly a touch less thanks to recent price drops.

Please note that all prices quoted are approximates and will vary based on location, supplier and time of purchase.  These figures were correct at the time of writing and should not be relied upon as hard fact, but used as a guide during your decision process.

Summary of price & where to buy

  • List of buying options included here
  • RRP of $49.97
  • Available for around $45
  • Works out at around 12 cents per day over 3 years
  • ProtectiveClean 4100 is a similar price

Reliability & long term use

Sonicare toothbrushes are made to the highest standards and have proven time and time again how reliable they are.

Inevitably some units will fail at some point, its something that affects all electronic products, particularly those exposed to water.

The plastics and other materials used on the brush are designed to resist wear as a result of the chemical makeup of things it will come into contact with.  

However, it is always advantageous to rinse and wipe down the brush with a cloth or towel to remove any excess grime and ensure a longer life for the brush.

Should the worst happen, it is covered by a 2 year warranty.


A solid toothbrush that performs well, there is a lot to like and what negatives I have are really small in the scheme of things. Most importantly, it does a brilliant job of cleaning the teeth.

Able to remove more plaque than a manual toothbrush, this is a good choice for first time electric toothbrush users, but for the savvy shopper, consider the alternatives, notably the ProtectiveClean 4100 which has some newer technology built-in and is likely a better all round buy for most.
