The Waterpik® Cordless Professional Water Flosser is a great solution when you want the convenience of cordless water flossing. Rechargeable and portable, it's perfect for use in smaller bathrooms or for travel.

The Cordless Professional's advanced dual water pressure control system allows you to personalize your water pressure intensity. Featuring an ergonomic design, the Cordless Professional includes rechargeable batteries and an easy-to-fill reservoir.

To meet your tooth brushing needs, the Cordless Professional comes with a Nano-Sonic® Toothbrush. Its vibrating bristles break up plaque, and the high-low bristle pattern accesses plaque in hard-to-reach areas.

Waterpik® Water Flossers are clinically proven to be more effective than traditional dental floss and Sonicare® Air Floss (Model HX8181) for reducing plaque, gingivitis, and gum disease. And it's perfect for anyone with braces or implants, and those with crowns, bridges, and veneers.

Rated 5 out of 5 by from Works Great! Easy to Use. This was my first Water Pic product. I bought on recommendation from my Dentist. Having several "pockets" in back of my teeth, plus I seem to make plaque relatively fast. This Water Pic works great. At first I was a bit sceptical, especially of its rather large size. But after getting used to it there are no issues at all. I like the fact that it is self contained and doesn't take up much space on the counter. I only charge it once a week. The self-contained reservoir holds plenty of water/mouth wash to clean all your teeth and gums. Best of all my teeth and mouth feel great. We'll see what the Dentist says next trip, but I'm glad I bought this item.

Rated 4 out of 5 by from No-Cord Feature is the Best! I use this water-pik often, especially after salads and other fibrous food. It is far superior to dental floss or tape, as there is no tissue damage to the gums from use. I have used Water-Pik many years ago, but found the need to keep it plugged in a nuisance at the sink. This portable cordless model is great for me! And it does not seem to need external charging too often. Since getting it, I charged it only once in three weeks after the initial 24-hour charge. It was so useful that I highly recommended it to my wife, who promptly purchased her own. It is also very easy to use and continues to do its job without complaining!

Rated 1 out of 5 by from Would definitely not buy this again I had a waterpik WP-360 before which I loved! Three things I don't like about this model. Holds less water than the last one. It runs out of water before I'm done, and if I tip it when the water is low, I have to adjust it so it's straight up to continue. I was excited about the electric brush that came with it, since I travel a lot. Big disappointment! It is no better than a regular toothbrush that you buy at the store. I own a sonicare, so maybe I was being unrealistic in my expectations, but seriously, that toothbrush is worthless. I wondered why there was a note from the company to call them if I was thinking of returning the watering. Big red flag there.. I wanted to like it, but I say no.

Rated 5 out of 5 by from A must have for travel... or home This little unit is not only great for teeth..its portable too! I have a larger unit for home use and the single unit for travel. The only suggestion I have that would be to make a breakproof case to carry it in thats not as bulky as a cardboard box is..something to protect the plastic, and encase all the attachments in one safe place, like a small zippered pouch to keep them together. I realize the water tank needs to be portable..but for each time I use it I have to refill the small unit at least 3-4x to clean my teeth. Other than that..great healthy tool for dental use!

Rated 4 out of 5 by from Protection better than brushing I've had the Waterpik for awhile now and use it every day. Amazing how much "stuff" comes out of your mouth even after brushing.

Rated 4 out of 5 by from What a clean feeling! Purchased after my dental hygienist used a similar product during my recent appointment. Does a great job at getting gaps between teeth clean, as well as addressing the "pockets" I have. A little messy; takes some getting used to, but not much. I use it before brushing with my electric toothbrush, & when I am all done, it feels like I just came from the dentist.

Rated 5 out of 5 by from 2 different piks I have gingivitis and had braces for almost one month. Within 2 weeks of using this product no more swollen gums or bleeding. I highly recommend this product especially if you have gum disease. It is very time consuming to floss your teeth with braces . Whatever food you can't remove with your toothbrush from the brackets this will. Love it!

Rated 4 out of 5 by from cool style easy to use I bought it and was so happy about its performance. I even pack it along when going on vacation. The design is awesome and easy to grip.Only drawback is when it's turned on it can splash everywhere. After that we started to turn it on with mouth closed. I would recommend it to anyone.
