Cordless Water Flosser 300ml Tank

The Waterpik C30 is a cordless oral irrigator built for daily plaque removal and gum care. Its 300ml reservoir delivers up to 60 seconds of continuous flow without refilling. Five adjustable pressure levels from 30 to 110 PSI suit sensitive gums, braces, and routine cleaning. Three S-shaped nozzles rotate 360° to reach back molars and tight spaces.

USB-C Battery Limits 60-Day Runtime

The built-in battery targets 60 days of typical use per charge and recharges via USB-C. The IPX7 waterproof rating allows shower use, but the charging port must be completely dry before connecting the cable to avoid short circuits. An initial full charge to 100% is required before first use to secure the rated battery longevity.

300ml Capacity Decides Refill-Free Cleaning

The single specification that determines whether this flosser fits a routine is the 300ml tank volume. It supports a full-mouth session in one fill, removing the need to pause and refill. Buyers who need longer continuous operation or a smaller form factor for minimal storage should consider a different capacity.

Questions about this item

Should I pick the 300 ml tank model or a smaller capacity?

The C30 comes only with a 300 ml tank, which provides a full-mouth clean in about 60 seconds without refilling.

What does the 99.99% plaque-removal claim mean when I actually use the flosser?

The WaveFlow pulse stream at 30–110 PSI removes up to 99.99% of plaque from treated areas, reaching deep between teeth and below the gumline.

How does the USB-C charging port limit daily use?

USB-C recharges the built-in battery for up to 60 days per charge; the port must be completely dry before plugging in to avoid short circuits.
