This X-shaped water stream, known as Quad-Stream technology, covers more surface area for a faster, deeper clean versus manual floss. Because of Quad-Stream technology, Philips Sonicare Power Flosser enables you to improve your gum health by 50% in just 1 minute per day!

Review: Works well - 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.
Review: Good water flosser, great warranty (had to get a replacement) - 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.

### ⭐⭐⭐⭐⭐ Good water flosser, great warranty (had to get a replacement)

### ⭐ Four Units, Same Fatal Flaw: Bottom Leak
*by D***S on May 13, 2025*

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.
