Product information

With Philips Sonicare’s HX6511/50 EasyClean rechargeable toothbrush you’ll enjoy a dynamic cleaning action that gently and effectively reaches deep between your teeth and along the gum line.

Q & As

Rated 4.7 out of 5 by 47 reviewers.
Rated 4 out of 5 by Good value product Nice and lightweight product - no issues with charger cable length. Teeth feel nice and clean afterwards without cleaning action being too vigorous. "Timer" function for each section of mouth to clean - when it reaches final section no warning it just switches off which may take some getting used to. Only came with one head so order extras ! 29 September 2015
Rated 4 out of 5 by Ticks all the boxes Just as it says on the advert ,I cannot think why I did not get one before. very pleased 29 September 2015
Rated 5 out of 5 by Great product, great service I purchased two Philips Sonicare electric toothbrushes for my daughter and son in law and they are both very pleased with them. And what a great service I received from John Lewis. I ordered on line and picked them up a couple of days later from Waitrose in Pentwyn, Cardiff. It was all very smooth and easy. Well done JL!!! 22 September 2015
Rated 5 out of 5 by Best toothbrush I've tried Having tried other makes of electric toothbrush, this outshines them all. It's quiet in use, battery life is huge, and it leaves teeth feeling really clean. The interval timer means each part of your mouth is evenly brushed. Can't fault this brush and the John Lewis price was truly unbeatable. 22 September 2015
Rated 5 out of 5 by Excellent toothbrush! This powerful toothbrush has a head that vibrates really fast, giving a thorough clean. The two-minute timer is divided into four periods of 30 seconds, separated by a beep, so you know when you've finished each quadrant of your mouth. I recommend it! 22 September 2015
Rated 5 out of 5 by I am sold Was impressed right after the first use- this was my first electrical toothbrush purchase - I am pretty happy and would recommend. It's also very reasonably priced and so far the reviews seemed accurate. Go for it! 07 September 2015
Rated 5 out of 5 by Great toothbrush! This is the first Sonicare toothbrush I've used and it's very good. I find the brush style much more comfortable to use than the round type. It feels less abrasive and gives a more effective clean. I've been using it for over 3 weeks and have just needed to charge it for the first time, so battery life is excellent. You could happily go on holiday for 2 weeks without needing to take the charger. If you want an effective brush without a range of other features, this is a good choice. 01 September 2015
Rated 5 out of 5 by Great offer, great price. Two toothbrushes were recommended by my dentist and hygienist. This Phillips one and an Oral B. I prefer the sonic clean and so opted to go with this toothbrush. I did quite a lot of research online and found that the only known problem with the Philips Sonicare is that the workings in the vibrating toothbrush may become brittle and cause failure after the year's guarantee and that would be outside the normal 12 months. With John Lewis offering a two year guarantee this will not be a problem, and if it dies after 2 years then it will still be as cheap as replacing non electric toothbrushes. It cleans beautifully,with a timer for 2 minutes and although this is the basic model, it is all you can really want. The charge seems to last for over a week on 2 timed sessions a day, so you could take this away for short breaks. The two pin plug has to have a shaver socket and is only a meter long. It may not stretch from a light switch socket to a surface below, so check if this is likely to be a problem for you. I charge it somewhere else as the lead would not reach my counter top. The brush is fairly small and can therefore get right to the back of your mouth. I am more than happy with my purchase. 25 August 2015
