The Coslus CX20 is a cordless rechargeable water flosser with a 300ml tank, a waterproof body and three color choices. The large tank means fewer refills per session than most travel flossers, which typically hold 150 to 200ml. It suits people who want a portable irrigator for travel or a small bathroom, but it is a basic model: expect a single pressure mode rather than the multiple settings and pressure readouts on premium rivals. Owners of budget cordless flossers like this generally value the tank size and the low cost of entry.
