Cordless Water Flosser with 300ml Tank

The usmile C30 is a battery-powered oral irrigator that delivers a pressurised water stream between 30 and 110 PSI. It removes up to 99.99% of plaque from treated areas using a WaveFlow precision pulse system. Five adjustable pressure levels suit sensitive gums, orthodontic appliances and everyday cleaning routines.

Simple Setup with Travel Lock

Fill the 300ml tank, select one of the five pressure levels using the plus and minus buttons, then attach an S-shaped nozzle. Lean over the sink and place the tip in your mouth before switching on. Press and hold the power button for five seconds to toggle the travel lock and prevent accidental activation in luggage.

Check Charging Port and Nozzle Fit

Ensure the USB-C charging port is completely dry before plugging in the cable to avoid short circuits. The IPX7 rating covers shower use but not charging while wet. Verify that one of the three included nozzles — standard, guidance or orthodontic — matches your cleaning needs before ordering.

Questions about this item

How do I verify the 30–110 PSI pressure range is working after setup?

Fill the 300ml tank, select a pressure level with the + and - buttons, and confirm a steady water stream reaches the gumline from the 360° rotating S-shaped nozzle.

What comes in the box and what must I buy separately?

The package includes the flosser, three S-shaped nozzles (standard, guidance, orthodontic), and a USB-C cable; no separate purchases are required for basic operation.

Which pressure level should I choose for sensitive gums versus deep cleaning?

Start at the lower end of the 30–110 PSI range for sensitive gums and increase toward the higher levels for deeper cleaning between teeth and below the gumline.
