Cordless Water Flossers

Best Water Flossers For: Portability, small bathrooms, and cordless convenience.

Types of Cordless Water Flossers

  • Traditional cordless water flossers feature an all-in-one handheld design with a smaller water reservoir and slightly lower overall water pressure as compared to plug-in countertop water flossers.
  • Cordless countertop water flossers offer full-size performance combined with the portability and convenience of a cordless design. They feature the pressure range, water capacity, and smaller separate flossing handle of a countertop unit, but in a compact size with no need for a power outlet during use.

These differences help create a more compact, lightweight, and portable device.
