What a 350ml reservoir covers
A 350ml tank gives you enough water for a full flossing session without stopping to refill. That matters most for braces, bridgework, or anyone who flosses longer than a quick rinse. The reservoir is sealed and cordless, so you can move from sink to shower without a hose.
How these flossers are built
These units are rechargeable and cordless, with a tank that holds 350ml. They use Type-C charging and carry an IPX7 waterproof rating, so they can be rinsed or used in the shower. Some come with a drainage and storage stand that keeps the base dry between uses.
Details that matter at this size
Mode count and tip count vary across these flossers. You will see 3-mode and 5-mode versions, with tip counts from 4 to 6. Color options include: green, black, pink. A U-shaped tip appears on at least one model, which changes the angle of the spray.
