Designed for small hands

The COSLUS T40 is a portable water flosser built for children aged six and above. Its compact, lightweight body fits small hands and slips easily into a backpack for school, travel or camp. The 180 ml tank supplies enough water for a full cleaning session without refilling.

Suits young users with braces or sensitive gums

Four pressure modes match different developmental stages, from a gentle low-speed setting for ages six to nine up to a high-speed deep-clean mode for ages twelve and over. An on-demand jet mode lets older children control the flow themselves. Buyers who need a larger reservoir or a countertop unit should look elsewhere.

Simple cordless setup with Type-C charging

Fill the tank, choose a tip and select a mode to begin. The 360° rotating nozzle reaches all angles while the IPX7 rating allows rinsing under water. A full charge takes 24 hours using any standard 5V USB adapter, which is not included. The main mistake is holding the tip too far from the teeth, which causes splashing.

Questions about this item

What water-tank capacity does the T40 have so I know if one fill covers a full session?

The 180 ml tank holds enough water for a complete daily flossing routine without refilling.

Will the 360° rotating nozzle on the T40 still aim properly if my child keeps using their existing brush-head holder?

The nozzle rotates freely through 360° so it can be angled around any fixed holder or cup without losing alignment.

Which indicator on the T40 confirms the battery is charging after I plug in a Type-C cable?

The built-in battery-level indicator lights up while charging and shows the current charge state once the Type-C cable is connected.
