Waterpik W40 300ml ADA Accepted 4 Modes 5 Intensity Levels Oral Care

Cordless water flosser with 300 ml tank

The Waterpik W40 is a battery-powered oral care device that delivers a pressurised water stream for cleaning between teeth and along the gumline. It offers four cleaning modes and five intensity levels so users can tailor the pressure to their comfort. The unit is IPX7 waterproof and includes multiple tips for different needs. Its cordless design makes it suitable for home or travel use.

Upgrade from string floss or fixed countertop units

This model replaces manual flossing and bulky plugged-in irrigators that tether you to a power outlet. The jump is worth it when you want adjustable pressure without a permanent bathroom installation. It also suits anyone who finds string floss difficult to manoeuvre around braces, bridges or tight contacts. The rechargeable battery removes the need for disposable cells.

Sustained daily use with 24-hour recharge cycle

A full charge takes 24 hours and supports multiple cleaning sessions before the battery needs topping up. The 300 ml reservoir holds enough water for a thorough clean without refilling mid-session. IPX7 sealing protects the internals during regular wet use and rinsing. The rotatable tip helps maintain consistent angle and pressure throughout the routine.
