About the Waterpik Cordless Pulse

The Cordless Pulse is a handheld, battery-powered water flosser from Waterpik. It has a removable 177 ml reservoir and two pressure settings, low and high. Waterpik gives the flow rate as 266 ml per minute and the pulse rate as 1,700 pulses per minute. LED indicators show the function and charging state.

It is fully waterproof, so it can be used in the shower. With a tip fitted it stands 29.85 cm tall, and the unit weighs 0.318 kg. The motor is described by Waterpik as ultra quiet.

Power comes from a rechargeable lithium-ion battery that is not replaceable. It charges in about 4 hours over USB-C, and Waterpik says a charge lasts up to 4 weeks. One fill of the reservoir gives up to 45 seconds of continuous flossing, so a full session usually means topping it up.

The box holds the flosser, two tips (a Precision/Classic tip and a tongue cleaner), a USB-C charging cable and the warranty. There is no travel bag or travel plug.

What owners report about the Waterpik Cordless Pulse

We found little owner feedback for this exact UK model. The summaries we could open point to the same two things: the small reservoir needs refilling mid-session, and the top setting can feel strong on sensitive teeth. Owners also like the size and the shower use.

Who the Waterpik Cordless Pulse suits

The Cordless Pulse suits anyone who wants a straightforward cordless flosser that fits a wash bag or a small shelf, and who is happy with a low and a high setting. The low setting gives a gentler option for sensitive gums.

Look elsewhere if you want a wider pressure range or a longer session without refilling. The Waterpik Cordless Advanced adds a third setting, and the Hangsun HOC700 and Philips Sonicare Cordless Power Flosser 3000 have larger tanks. If you want more tips or modes, the COSLUS C50 and the Bezvoi Mini Portable Water Flosser for Travel come with more variety.

How we score it

Every score here comes from our ranking model; no editor sets the order. Too few review sites cover water flossers for their verdicts to lead, so this ranking is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 23 models for this guide before settling on these ten.

Brands can't pay to be included or to move up. We last checked these picks in October 2026.
