Power Flosser 5000, White, HX3811/20

Purchased one year ago. Easy to use and clean. My wife and I use it every night. This is corded version as I could see no benefit in a cordless model. NOTE: Recent problem. Machine turned off and both lights blinking orange, no water flowing. Nothing Philips suggested worked. Found an easy fix. I figured the problem was water flow. I removed the reservoir and checked the rubber gasket in the top of the pump housing by VERY gently probing it with the nozzle to make sure it was clean, no buildup, and no air bubbles. Then I checked the valve in the bottom of the reservoir to make sure it was clean and easily opening and not blocked. Then I filled the reservoir with hot water, made sure the water was going through, and turned the pump on at the highest pressure setting. Using just the handheld wand without the nozzle, I turned it on and let the hot water run through until the reservoir was empty. The flosser has been working fine ever since.

I liked this water flosser but it developed a leak within two years. I’d give it fewer stars for quality but Philips honored its 2y warranty and replaced the unit with an upgraded model which I like better.

After a lot of research, I found that this water flosser is widely considered one of the best on the market when it comes to dental hygiene. The brand has a strong reputation, and in terms of actual flossing performance, it truly delivers. Clean, powerful, and effective—when it works. Unfortunately, that’s where the good news ends. I’ve purchased this model three times over the past couple of years. One of those units was even replaced under warranty, so in total, I’ve gone through four of these—and every single one developed the exact same issue: leaking from the bottom. Whether it was weeks or a couple of months in, all four units failed the same way, and always within a year. The last time, I thought I was being smart by buying insurance along with the device, especially since it was on sale for $60. The unit started leaking again just like the others, and it was replaced. But only a couple of months later, the replacement unit also began leaking from the bottom, just like clockwork. Since it was a one-time replacement, I could no longer get another one—only a $60 refund, which doesn’t cover buying a new one now that the price has gone up. At this point, I’d have to be out of my mind to buy a fifth unit, knowing this is a recurring defect that hasn't been addressed. It’s incredibly frustrating because the product could be amazing. It should be amazing. But if a $60+ device can’t last more than a few months—and every single unit fails the same exact way—then that’s not bad luck, it’s a design flaw. Buy at your own risk. If they ever fix the leak issue, I’d be the first to recommend this product. But until then, I simply can’t.

Worked great for 2 years, did exactly what it was supposed to and never had issues. Improved my gum health for sure! Unfortunately it has completely stopped working 2 years and 2 months after purchasing, 2 months after warranty lapsed. Haven't decided if I'll purchase a new one or try a different brand, I hoped it would be longer lasting

I’ve never liked using dental floss because it’s messy. I used to have a portable water flosser, but the tank was tiny, so I had to refill it multiple times — which eventually made me floss less and less. The battery also wore down over time, and I could only do half my mouth on one charge before it finally died. I’ve been wanting a corded one with a bigger tank, and I got a great deal on Black Friday. I’ve been using it twice a day, and I’m so happy with the big tank — two full tanks cover a whole month of flossing! No more worrying about the battery running out. My gums feel healthier, and my teeth feel so much cleaner.

I had all on 4 dental implants and ClearChoice gave me the more commonly known water pick brand device and while I appreciated they provided that as a part of their service, I was not sad when it broke in a month. It was pretty cheaply constructed, a fat footprint, extremely loud and vibrating hard on my counter and the design is so much nicer with the off switch on the magnetic wand (the magnet holds it in place, which seems cleaner somehow, since its only touching the back). This one was only a bit more expensive, and not by much, assuming they paid what I saw on Amazon when I went to order one and found this. Some people complained that the power supply is external and too large, but where my plug lands, it doesn't matter to me, and I love the smaller footprint on my counter. I had implants and a really rough recovery with slowly healing dry socket and hole into sinuses and depend a lot on the water pick to avoid infections. This is so much better, I wish I'd had it sooner.

Should have known. Worked great until the plastic internals developed a crack and now sprays water that leaks from bottom of unit. 1.5 years. Avoid. --- Updating: 1 star to 3 stars I am giving 2 more stars because the 2 year warranty and just how often I used this because I genuinely love this thing. However, although the product was replaced under warranty I still don't like how fragile stuff like this has become. Feels like they are built to last around the warranty period and likely cannot be repaired, only replaced. Very wasteful.

Tuve el waterpik estacionario y ahora tengo este Philips. - Se siente de mayor calidad el Philips, pero un poco mas potente el waterpik. - Al año exactamente se descompuso el waterpik, a ver cuánto me dura el Philips.

Ich habe die Munddusche 1 Jahr in Betrieb und muss sagen, dass ich nach wie vor bin begeistert bin. Immer gern wieder.

I absolutely love the Philips Sonicare Power Flosser 5000! It’s been a total game-changer for my dental care routine. Paired with my Sonicare toothbrush, it keeps my teeth feeling incredibly clean and looks fantastic sitting on my bathroom counter—sleek and stylish without being bulky. What blew me away, though, is how well it works. I tossed my old Waterpik almost immediately after trying this. It’s just so much more intuitive and effective. The Sonicare flosser removes food particles effortlessly, and the thoughtful features make a world of difference. For example, it cuts power to the motor if water flow is interrupted and stops the flow entirely when you dock the pick. It’s such a smooth, well-designed system—it feels like the engineers had an opportunity to talk to the users during the development process. Lol, while keeping the marketers at bay. Philips has absolutely nailed it with this product. I’m delighted and can’t imagine going back to anything else. If you’re serious about keeping your teeth healthy and want a device that works as well as it looks, this is the one!

I qm very happy with this product Its unbelievable in extra care of teeth 👍👍👍

This is the greatest flosser! We tried a Waterpik, but it was so noisy I would've had to wear ear protection to use it in our small bathroom (and I doubt our condo neighbours would've appreciated it!). True to its claims, it is very quiet. On its lower speeds, you can barely hear it if you're not in the room where it's being used. It cleans very effectively, yet comfortably. When you're done, you remove and rinse the nozzle and click it back into the handle. The coiled cord then folds neatly back into the base and you pop the wand back into its magnetic holder... So easy. If this is your first flosser, I think it's a great choice. And if you're tired of hearing your loud Waterpik, you'll find this one a relief. It's good to know some people still care so much about quality. 😁👍 P.S., Amazon: Why is one of the star ratings you're offering here "Flavour"? Does it really come in different flavours? 😄
