300 ml Water Tank Capacity

The Waterpik W40 is a cordless oral irrigator with a 300 ml water tank that delivers 1400 to 1800 pulses per minute. It is designed for users who want a rechargeable flossing device with IPX7 waterproofing for convenient bathroom use. The unit weighs 0.431 kg and includes multiple jet tips for different cleaning needs.

Suitable for Daily Gum Care

This flosser suits adults and teens who want to reduce gingivitis and remove plaque between teeth with adjustable pressure settings. It is not intended for buyers who need a countertop model with a larger 600 ml reservoir or those who prefer a device that operates while plugged into mains power without recharging.

Sustained Use Behaviour

A full charge requires 24 hours and supports multiple cleaning sessions before the battery needs recharging again. The 300 ml tank allows a complete flossing routine without refilling, and the IPX7 rating means the handle can be rinsed under running water after each use.

Questions about this item

Does the W40 require a separate USB-A power adapter to charge?

Yes, the unit charges from any 5 V USB-A adapter, which is sold separately to reduce waste.

Can the five included jet tips be shared with the older C20 model?

The W40 ships with 3 + 1 tips; compatibility with the C20 is not confirmed in the specifications.

How do I verify the IPX7 waterproof seal is intact after the first charge?

Submerge the handle briefly; if no water enters the battery compartment the seal is working.
