My original Philips AirFloss was brilliant and kept going for many years up until recently, unfortunately when I tried to replace it I found it was no longer available so purchased this Philips Sonicare.This is absolutely useless, the original AirFloss had a pressurised jet of water that could be directed between each tooth, this thing issues a constant flow of bubbles which do absolutely nothing other than make an enormous mess if you should inadvertently open your mouth while your fingers on the button. this Philips Sonicare is not fit for purpose and I would advise anyone thinking of buying one not to bother, save your money. I wouldn't have left 1 Star but the review insists, the rating is not published without.

Very disappointed, only instructions provided are a little picture diagram that is difficult to see and follow. Got very wet trying to use it, quite bulky to hold. Its very easy to hit the on button when assembling which soaked the room not just me.Tried to get instructions by phoning customer service they just suggested using an on line video and told me instructions are not on the list of what is included!!! An online video is not practical when dealing with water going everywhere and also doesn't fully explain how to use it and maintain it. First person I spoke to was trying to tell me to wet the brush!!!!Our biggest disappointment is that John Lewis phone customer support is not what it used to be. Its putting us off further purchases.

In December 2023, I was sent a replacement power flosser 3000 for the same product I purchased a few months earlier. This replacement was issued because my original flosser (two months old) charge cord got stuck and broke off inside the flosser.Last night when I went to use the Powerflosser I smelled a burning smell and pulled the charge cord out from the charger. When I did this I noticed the end of the charger was very hot and the inside of the charge port looked slightly brown. As soon as I touched the hot end of the charge cord the plastic melted on my fingers and can no longer be inserted into the port. I’m not sure if melted plastic is also inside the port.Today I spoke with a representative via chat and was told in approximately 10 days someone will ...

Meanwhile I'm out a flosser that Ive only had for three months. As a note, I also have a Phillips toothbrush plugged in to the same outlet so it's not an electrical problem on my end.

I find it powerful that the water jet burst away any food that left between teeth, was handy to use thanks to the built-in battery and popular usb c charge port. Clean and functional design. It is also easy to pack away in a carry bag, telling you that it’s always ready to go out with you. But unfortunately even before it get the chance to travel with me, it has gone malfunction after 2 months of use. The cause was likely that water gets in and corroded the circuit board. Good news is, I contacted Philips warranty and within a week a new one arrived at the door. Bad news is, I start to suspect that there is a design/manufacturing issue that my other one might be dead within 2-3 months. Opened up to find out why.

Good news is, I contacted Philips warranty and within a week a new one arrived at the door. Bad news is, I start to suspect that there is a design/manufacturing issue that my other one might be dead within 2-3 months. Opened up to find out why. Start from the bottom of the device body, gulp of water dashed out, lower part of the circuit board see heavy oxidation and corrosion, there was sign of water accumulating at the bottom part of the body. Back of buttons were sealed properly, no risk of water ingress, back of USB C port sealed properly, no risk of water ingress, bottom cover has a rubber ring, no sign of water ingress either. The only part without a seal ring seems to be the top part of the body, where the nozzle connects with the body. Water might get in from there during use and accumulate. But all these is only a rough guess through observation.I hope they have updated the design and it would last longer. For now, I would either hang it upside down or sit it side way with button facing up after each use.
I have had three of these in just over four months and all failed with the same or very similar problem. That is, they lost power resulting in weak and ineffective flossing. Two were replaced and the last one resulted in a refund.I timed how long it took to empty the water reservoir on the last one. It was over six minutes and even then there was water left in the reservoir. I attach photos of this. This compares with well under two minutes to completely empty the reservoir when the flosser was initially used. No-one expects to spend that long flossing their teeth and then to find it has little effect.The flossers were all fully charged when the fault became evident so it's nothing to do with state of charge in the battery.

I do not believe that an item designed to floss teeth can be classed as fit for purpose when it has no power in the water jet and takes too long to use the water supply in the reservoir.I previously left two reviews saying more or less what I'm saying here but JL wouldn't publish them. The only reason I believe that prevented them being see by potential buyers is that I mentioned another company in the review and JL won't publish if you do that.If you are thinking of buying this flosser, please read some of the other reviews. You will see a number saying something similar to my own experience.
This was a replacement for a prior model. The experience is totally different ,time will tell if this model lasts longer than the other.It uses a lot of water and the first few tries there was a lot of learning and frankly water everywhere. Happy that this does remove debris from between teeth, unsure if it helps the gums. There is quite a force and this might make it unsuitable for childrenThe deep clean does feel like it's helping the surface of the tooth.If teeth are sensitive avoid really cold water when fillingEasy to set up and replace the 2 different heads
I'm extremely disappointed with the quality of this water flosser. It didn't even last a month before it stopped working intermittently while using it. The power was underwhelming from the start, and it gradually weakened until it would only run for a few seconds before shutting off. The concept behind this product is fantastic and a much better alternative to traditional flossing. I hope Philips addresses these issues and makes the product more durable before releasing the next generation to the market. I am hooked on the idea of water flossing now, but at this price, it needs to work!
I previously had a Philips Airflosser and that was fantastic. I bought this flosser last year and apart from trying to use it for over a month it sits in the cupboard unused. With the airflosserr if you were about to go out and wanted to check your teeth that was easy, you did not get water running down your freshly made-up face. It might be OK for guys but it is damp and sprays water and it doesn't clean nearly as well as the previous model. Why, oh why did Philips stop making the previous model. It was, compact, neat and did the job beautifully. With this one you still haves to use something else to remove debris from your teeth. I am afraid it is RUBBISH. It cost £100 for something that does not work. I have heard of people who use in it in the shower and I can ... MoreI previously had a Philips Airflosser and that was fantastic.

Great power flosser. Its very easy to setup and they include to heads. One is the regular one that shoots a one stream of water, and the other one is the one that shoots 4 streams of water and has soft rubber head. You just insert the head you want to use and then fill up the reservoir. Then make sure the battery is charged and then you can choose between 3 levels of power and two modes of cleaning (one is a regular stream, the other one is a deep cleaning that shoots pulsating streams of water). They recommend to start ant the minimum and go up from there, depending on how sensitive your gums are. I liked the quad stream nozzle better as it shoots 4 streams of water and cleans better. I have very sensitive gums and I usually use toothpaste for sensitive gums and I ... MoreGreat power flosser. Its very easy to setup and they include to heads.

I have very sensitive gums and I usually use toothpaste for sensitive gums and I did not have any problems with this power flosser at all at its lowest strength. One thing that surprised me is the amount of water that splashed everywhere when I first used it with my mouth open, you have to close your mouth when doing so if you don't want water splashing everywhere. After a while your mouth will fill up with water of course and then you can spit it out. At least I had to do that otherwise I would have water everywhere in my bathroom. I did notice it did clean my teeth, specially in between and also the gum area, its like flossing, but with water. Of course you still have to brush your teeth so I use the device once a day (at night actually) after brushing, before going to bed. I guess you can consider it a personal device, but I looked around and saw that replacement nozzles are very cheap so I plan to buy and extra pair of the quad stream ones so my partner can use them at night too, we would just switch nozzles after each use. I highly recommend it as flossing is as important as brushing your teeth and this is a great replacement for floss.
I love this thing! I have had a variety of WPs over the years and the thing I always detested about them was the stupid spiral plastic cord which got in the way and was just an utter mess to keep clean etc. I always avoided these cordless ones because I imagined they'd lack the power. I was totally wrong. This has more than enough power and I am never using the max level. I can use this and wipe it off with a towel and it's clean... and dry. Literally the only thing I'd change about this would be a slightly larger reservoir for the water because I, not all the time but often, run out like 10 seconds too fast... but no big deal, I just put some more in quickly by flipping open the port, fill and close. Honestly, this for me is perfect not to mention, it is totally ... MoreI love this thing!

Honestly, this for me is perfect not to mention, it is totally travel ready. Yeah, you might need to take the hand piece in your carry on because of the battery but no biggie. We have to do that with so many other useful things too! Buy it... this has a two year warranty as well which I have used with my old sonicare toothbrushes too and they always replace it and honor their warranty without any problems as log as you have an image of your receipt. If this broke and was out of warranty, I'd happily buy another that day.
