The Waterpik ION (WF-31) is a cordless, rechargeable water flosser built for countertop-free use. It runs up to four weeks per charge, offers 10 intensity settings, and uses QuietPulse technology to keep noise down in shared bathrooms. The removable reservoir holds enough water for 90-plus seconds of flossing, and the handle swivels 360 degrees to reach back teeth. It suits people who want full Waterpik cleaning without an outlet, though corded models deliver more pressure and a bigger tank.
