The Coslus Cordless Water Dental Flosser is a rechargeable oral irrigator with a 300 ml tank and a portable, travel-friendly body. The large tank is its main edge over slim rivals like the Waterpik Cordless and Philips Sonicare Power Flosser, which need refills mid-clean. It suits people with braces, bridges or tight contacts who want a cordless flosser without paying flagship prices. Owners rate it well overall, though some find the spray pressure modest and the build plasticky.
