Waterpik Cordless Pearl Portable Water Flosser, Rechargeable, White

Why it's worth it

The Cordless Pearl is a rechargeable, handheld Waterpik with four tips and two pressure settings. You give up tank size and fine pressure control, but you gain a device you can store in a drawer and use anywhere in the house.

If your bathroom has one outlet and it's already busy, this is the Waterpik to get. The whole unit is a handle with a tank on it, under a pound, and it stands up on its own or tucks into a drawer. It charges over USB with a magnetic connection, so there's no cord snaking across the counter between sessions. For a lot of people, that's the difference between using a flosser daily and leaving one in a cabinet.

It's the quiet one in the Waterpik lineup. Waterpik builds this model with its quieter flossing technology, and owners generally back that up — it's noticeably less obtrusive than a countertop unit. The tip still rotates 360 degrees, and the grip is narrow enough to angle behind your back molars without contorting your wrist. Same PrecisionPulse pulsation you get from the Aquarius, same ADA-accepted brand pedigree, in a much smaller package.
