The Coslus CX51 is a cordless, rechargeable water flosser with a waterproof body and an ergonomic grip. It is aimed at people who want a portable alternative to string floss and to countertop Waterpik-style units. Against rivals it trades the large tank and wide pressure range of plug-in models for cordless convenience, and it sits in the budget tier of cordless flossers. Expect a smaller reservoir and fewer pressure settings than premium units, so it suits light daily use more than heavy periodontal care.
