COSLUS T40 oral care water flosser 300 ml 4 modes 11 intensity IPX7

Cordless water flosser with 300 ml tank

The COSLUS T40 is a battery-powered oral irrigator designed for daily plaque removal and gum care. Its 300 millilitre detachable reservoir supplies enough water for a full cleaning session without refilling. Four selectable modes and eleven intensity levels let users match pressure to personal sensitivity. The IPX7-rated body withstands immersion during use in wet environments.

Pressure range tops out at 150 PSI

Water pressure adjusts from 30 to 150 PSI across the available settings, delivering 1400 to 1800 dual-pulse streams per minute at the highest levels. The DIY mode allows an eight-level custom curve that the unit remembers for the next session. Battery recharge requires twenty-four hours for a full cycle. No wired connection or external power adapter operates the device while charging.

Nozzle clicks straight into the top slot

Insert each tip until the sealing ring seats fully at the bottom of the opening; a visible gap indicates a leak path. The 360-degree rotating head simplifies angling between teeth and around orthodontic hardware. Memory recall restores the last-used mode with one press, reducing setup steps. The unit suits travellers and multi-user households but not buyers who need continuous mains operation.
