Cordless water flosser with 300 ml tank

This cordless water flosser holds 300 ml of water and runs on a rechargeable battery. It offers three pressure settings and comes with four tips. The IPX7 waterproof rating allows use in the shower. A three-hour charge provides up to 30 days of use.

Suits travellers and shared bathrooms.

The compact, cordless design suits travellers, families sharing one unit, and anyone who prefers a shower-safe device. Buyers who want a countertop model with a larger reservoir or continuous mains power should look at a different type of irrigator.

300 ml reservoir capacity

The 300 ml water tank delivers roughly one full cleaning session per fill, halving the refill frequency of smaller 150 ml or 180 ml units. This capacity is the key figure for deciding whether the device matches your routine.

Questions about this item

Which model should I pick if I want the largest water tank among the listed options?

The W40 and the C20 variants each offer a 300ml tank, which is the highest capacity shown in the comparison table. The E2 desktop unit provides 600ml, but it is a countertop model rather than a cordless flosser.

How long does the 30-day battery claim last when I use the flosser twice a day?

The manufacturer states a 3-hour charge delivers up to 30 days of continuous use. Typical twice-daily sessions fall within that estimate, so you can expect roughly a month between charges.

What does the IPX7 rating mean for daily use and charging?

IPX7 means the handle can withstand immersion in water up to one metre deep for 30 minutes, so it is safe for shower use and rinsing under a tap. The charging port must be dry before you connect any 5V adapter.
