ADA-Accepted Cordless Water Flosser

The COSLUS W40 is an ADA-Accepted cordless water flosser designed for users who want effective interdental cleaning without a countertop unit. It targets plaque and food debris between teeth and along the gumline to help reduce gingivitis and bleeding. The device suits adults and teens seeking a portable oral hygiene tool. It is not for buyers who need a high-capacity reservoir for extended family use.

300ml Tank with IPX7 Waterproof Build

The integrated 300ml water tank allows a full cleaning session without refilling and the IPX7 rating means the whole unit can be rinsed under running water. A rechargeable battery powers the device, removing the need for a fixed power outlet near the sink. A 5V USB-A adapter is required for charging and is sold separately. The compact dimensions let it fit in a travel bag or small bathroom. It does not suit users who prefer a direct mains-powered appliance.

1400–1800 Pulses Per Minute Sustained

The dual-thread 0.3mm nozzle delivers 1400 to 1800 high-pressure pulses per minute across three simplified modes calibrated for consistent output during a full tank cycle. The battery indicator shows remaining charge so performance does not drop unexpectedly mid-session. A full recharge takes 24 hours to restore the rated pulse rate. It is not for users who require adjustable pressure beyond the three preset levels.

Questions about this item

How long will the 300ml tank last before I have to refill it during a full cleaning session?

The 300ml tank capacity is designed to last through a complete flossing routine without needing a refill, unlike smaller 150ml tanks that require topping up mid-session.

Does the IPX7 waterproof rating mean I can safely rinse the whole unit under the tap after daily use?

Yes, the IPX7 rating allows you to rinse the entire device under running water for hygiene without damaging the internal components.

The box says adapter sold separately — will any 5V USB-A charger I already own power it?

Any standard 5V USB-A adapter will charge the unit; the port is universal so you can use an existing phone charger or purchase one from COSLUS.
