The C30 is a cordless water flosser with a rechargeable battery and a black finish. It uses a pulsed water jet to clear food and plaque between teeth and around braces, where string floss struggles. It suits people who want a compact flosser for travel or small bathrooms. Against rivals, it is a basic model: expect a fixed or limited pressure setting and a smaller tank than countertop units, so you may need to refill mid-clean.
