Portable oral-care flosser

The Waterpik Cordless Pulse 3100 is a battery-powered water flosser designed for daily plaque removal around teeth, gums and orthodontic appliances. Its compact form suits travellers and anyone who prefers a cord-free routine at the sink or in the shower.

Waterproof build with USB charging

A sealed, waterproof body allows safe use under running water while the non-slip grip stays secure when wet. The 6 fl oz removable reservoir is top-rack dishwasher safe and the lithium-ion cell recharges in 4 hours via the supplied USB-C cable; a charge indicator shows remaining power.

Upgrades basic string floss and single-speed units

This model replaces manual floss or entry-level flossers that offer only one pressure setting. The jump is worthwhile when you want two selectable pressures, 45 seconds of continuous flow per fill and ADA-accepted PrecisionPulse performance without a tethered power cord.
