Water flossers
Water flossers send a pulsing jet of water through a tip. They come as countertop units, cordless models and brush-and-flosser combinations.
- Countertop tank
- often 600 ml or more
- Cordless tank
- often 150 to 300 ml
A countertop flosser has a large reservoir, a mains-powered pump and a hose to the handle. A cordless flosser carries a smaller tank in the handle and runs on a battery, which suits small bathrooms and travel.
Compare the pressure settings (often stated in PSI), the tank in ml, the number and types of tips, and how the reservoir is filled and cleaned. We quote maker statements only, not health claims.
