About this item

Product details

The Waterpik Aquarius water flosser (WP-660) is designed for a wide range of users seeking a more effective and convenient way to maintain daily gum health and oral hygiene. It is especially ideal for people with braces, implants, bridges, or crowns, as it helps clean areas that traditional floss often cannot reach. Those with sensitive or bleeding gums can benefit from its adjustable pressure settings, allowing them to start at the lowest level and gradually increase intensity as gum health improves. It is also a great alternative for individuals who find traditional string floss difficult or cumbersome to use. The unit is family-friendly, featuring 7 color-coded tips so multiple users can safely share the same device, and it is suitable for children ages 6+ when used under adult supervision, beginning on the lowest setting. Designed for convenience, it requires just one minute per day, making it easy to incorporate into even the busiest routines. The 7 specialty flossing tips address a variety of dental needs (orthodontics, periodontal pockets, dental work). The 1-minute timer with 30-second pacer ensures thorough water flossing of all areas, and a removable water reservoir with flip-top lid makes it easy to fill. The special 360-degree rotating tip handle easily reaches your whole mouth, even back teeth. This electric plug-in countertop model measures 4.7 x 10.35 x 3.8 with tip at the base (WxHxD inches). The Waterpik Aquarius water flosser removes up to 99.9% of plaque bacteria that causes gingivitis, bleeding gums, cavities, and bad breath from treated areas and is clinically proven up to 2X as effective as string floss for removing bacterial plaque and improving gum health. Waterpik is the #1 water flosser brand recommended by dental professionals, and the Waterpik Aquarius water flosser is accepted by the American Dental Association (ADA) for safety and effectiveness. Backed by a 3-year manufacturer's limited warranty, see product manual for details.

Great Flosser

After three years of daily use, our Waterpik flosser quit. I didn't even research another brand. Our Waterpik served us well. As much as I liked that one, this one has it beat! The tips go on and come off much easier and the top is attached which makes it splashfree, easy to close and a much better design in my opinion. The cord coils up nicely and does not drip onto the countertop. Will never switch from Waterpik!

Continued improvement

Overall experience has been great! Compared to previous Waterpik units I have owned, this model is an improvement. As I recall, my last unit did not have a water on/off control on the handle. My WP-660 has this. Also, the massage feature is new to me with this model. My dentist is impressed with my improved oral hygiene.

A bit noisy but works fantastic

I've used it daily since purchasing. Extremely easy to use once I remembered to keep my mouth shut. It's a bit noisy and I wish the water storage tank was a bit larger. I would definitely buy again and I'm curious what my dentist will say on my next visit.
