The 3 BIG Questions about the HX6511/50…

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 (view on Amazon). If we have missed something, let us know in the comments.

If you want more detail, you can read our full Philips Sonicare EasyClean HX6511 review further down the page or watch our video review.

To provide the best possible insight, we review a wide range of brushes and frequently update our recommendations.

1. Is there anything drastically wrong with this toothbrush?

No, it’s a good brush which we have given a rating of 4/5. We rate it as the best mid-range choice in our roundup of the best toothbrushes.

We look at the pros and cons further down the page, but one of the main drawbacks is that it is expensive compared to an equivalent from Oral-B. The Sonicare Series 3 offers more cleaning modes but is more expensive.

2. Which other brushes should I consider in this price range?

Really there is little to fault here, as an entry level brush, the EasyClean still gets our recommendation, but other options do represent a bit better value.

Oral-B’s Pro 2 2500 is cheaper and offers more, whilst the ProtectiveClean 4300 is a more premium option but could be worth the extra spend.

3. Where’s the best place to buy the HX6511 EasyClean?

Typically we recommend Amazon because it is very competitive on price and often has special offers running. It also offers free delivery. However, it’s always worth checking out other retailers as well.

Check the links below for the cheapest price for the HX6511/50 amongst UK retailers. It’s always worth checking eBay too.

And now for a bit more detail…

Sitting just above the budget brushes the HX6511 EasyClean is not overly expensive.  However, for the price is not the best value in our opinion. Find a good deal on a good day and you can actually pick this brush up at a bargain price, but the Oral-B equivalent will always be cheaper. The sacrifice with the Oral-B? Battery life.

Variants of this brush

The 6511/50 Sonicare brush being reviewed here is one of the more common amongst the EasyClean range, but for the sake of clarity, you should know that there are slightly different variants within the EasyClean range.

The main difference is the brush heads.

Some retailers may or may not clearly label the different models, so it is worth being vigilant and understanding the differences.

  • EasyClean HX6511/50 – This is the EasyClean in Glacier Green with a ProResults standard sized brush head
  • EasyClean HX6511/43 – This is the EasyClean in White with a DiamondClean standard sized brush head
  • EasyClean HX6515/06 – This is the EasyClean in Glacier Green with 5 x ProResults standard sized brush heads

Pros & Cons

The positives

  • Battery Life – 3 weeks or 84 minutes of brushing time from this compact brush make it a very compelling choice if you do not have a charger in your bathroom or if you need it to last for longer.
  • Power Saving – To help reach its potential battery life a small but nice feature is that it automatically powers off when the 2 minute cycle of the daily clean mode is complete.
  • Easy-start Mode – A mode that automatically increases the power of the brushing over the first 14 uses to help you and your gums adapt to the different feeling of a Sonicare electric toothbrush cleaning your teeth.
  • Packaging – Very environmentally friendly the vast majority can be recycled and not put into landfill.

The negatives

  • Expensive – This brush is a little bit more expensive than one would like or think of for a brush with only one cleaning mode. What makes it worth the higher price is the Philips brand and battery life.
  • Clinical Design – The design is very clean and cosmetic looking, primarily white in colour the only real colour is the light green colour power button and the green bristles of the brush head.
  • No travel case – No travel case is provided in the box with the EasyClean HX6511.

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 colours 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.

On the front is a mint green colour power button just above halfway up the body of the brush.

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.

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.

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.

Philips_Sonicare_HX651150_Image_F 

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

This brush is not really ideal for those who have specialist oral health requirements.

The clean mode lasts for 2 minutes in total or 120 seconds.

Activated by pressing the power button, the brush head will kick into life with the bristles on the brush head moving to offer up to 31,000 strokes per minute.

Philips_Sonicare_HX651150_Image_D

Built into the brush is a timer or quadpacer.  At 30, 60 and 90 seconds the quadpacer will provide an audible tone 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.

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.

Over the days and weeks that you use the brush the LED indicator will change colour to reflect the remaining battery power in the brush.  A solid green light indicated 50-100% power remaining, whilst a flashing green light suggest 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

Included in the box is just one brush head, the standard ProResults brush head. This can be detached from the brush and should be changed every 3 months.

Optional extras that can be fitted to this brush include a mini ProResults brush head which has a smaller head suitable for smaller mouths or those with limited jaw movement and assists in getting into tighter positions within the mouth. 

Summary of Design, Usability, Clean & General Use

  • Clinical looking brush
  • All white with a mint green power button
  • LED indicator on the power button for battery status feedback (different colours for different power percentage remaining)
  • Ridges on the rear for grip
  • Slim and comfortable to hold at just 130g
  • 1 cleaning mode known as ‘clean’
  • Built in quad pacer and 2 minute timer tells you when to change quadrant and finish brushing
  • Quiet brush with a high pitched humming sound
  • EasyStart feature which increased brushing power over 14 days

Battery Life

There is no faulting the battery life on this brush.  It is superb and knocks the competition for six.

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

Marginally larger than comparable brushes the slight increase in size is outweighed by the battery life.  If you went away on holiday you would not need to worry about taking a charger with you.

If multiple people use this brush (remember to change the brush head) the usage time will still be up to 84 minutes of brushing, but the number of weeks usage will decrease.

Philips_Sonicare_HX651150_Image_G

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.

Included in the box is a charging station.  Connect this charger to the 2 pin socket in the bathroom.  If you do not have one, purchase an adapter and you can use with conventional 3 pin mains in the UK.

When not in use the brush can be kept on the charging to keep the battery topped up.  Do remember constantly being sat on the charger can reduce the working life of the battery, but doing so does not invalidate the warranty.

To prolong the battery life it is good to run down the battery life completely occasionally.

Summary of Battery Life

  • 84 minutes of usage time or 3 weeks usage based on 2 cleans a day
  • Powers off the brush at the end of a cleaning cycle
  • A charger included in the box (comes with a 2 pin shaver socket connector)
  • Prolong battery by discharging fully every so often

Price & Where To Buy

The HX6511/50  has a recommended retail price of £90.  However, it is easy to pick this up for around half the price.

Typically we recommend Amazon, but shop around and check the price of other UK retailers here.

With a little savvy shopping you may get this for less than £40 but at the time of writing, we were able to purchase this from £40 to £50.  You tend to find the best prices online (we recommend checking out Amazon), with the high street often being a little more expensive.

Philips_Sonicare_HX651150_Image_C

For the price, you get a reasonable brush. You can source equivalents cheaper but the battery life is not so good.  An extra brush head or travel case in the box would give the feeling of a little more value for money.

Here at Electric Teeth, we like to work out the cost of ownership over what we deem to be the average life of an electric toothbrush, which we deem to be 3 years.

Sadly Philips only offer a 2 year warranty whereas Oral-B offer 3.

This brush requires replacement brush heads for each user every 3 months.  Replacement heads can be purchased in packs of 4 and are priced on average between £18 and £20

Using the average cost (based on one user), the EasyClean HX6511 will cost £88 or just 8p per day to own.  This does not include the cost of water, toothpaste and electric to charge it, but you get a rough idea.

There is a good chance the brush will last longer, which means you will obtain even better value from it.

Please note that all costs quoted are approximates and prices will vary based on location, supplier, time of purchase.  These figures should not be relied on as hard fact but as a guide, based on real information at the time of writing.

Summary of Price

  • RRP of £90
  • Available for around £40
  • Replacement brush heads are about £19 for a pack of 4
  • Works out at around 8p per day over 3 years

Reliability & Long Term Use

Any brush exposed to water, toothpaste and saliva will over time built up deposits of grime on the brush handle and around the brush head attachment.

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.

Conclusion

It is not a feature rich electric toothbrush.  It looks really quite clinical too, but what it does is do a job and do it well.

Your teeth will feel clean after using the HX6511/50.  The sonic technology helps remove up to 2 times more plaque than a manual brush.

For sheer value for money, the Pro 2 2500 from Oral-B is the better buy.

Although a little more expensive you get the premium Philips brand name and a battery life of 3 weeks.
