Maintaining optimal oral hygiene on the go has never been easier. The Waterpik Cordless Pulse WF-20 combines clinical effectiveness, modern convenience, and sleek portability in one compact device. Designed for people who want professional-grade cleaning power without the bulk, this cordless water flosser redefines what portable oral care means.
Design and Build Quality
Lightweight, Sleek, and Ergonomic
The Waterpik Cordless Pulse WF-20 features a streamlined, ergonomic body that fits comfortably in hand. Weighing just over half a pound, it’s ideal for travel and daily use alike. The minimalist white finish with soft-touch accents gives it a clean, modern aesthetic that matches any bathroom setup.
Waterproof and Durable Construction
Its IPX7 waterproof rating ensures full protection against splashes, making it perfectly safe for use in the shower. Waterpik’s durable plastic build also guarantees longevity and reliability, even with daily use.
Advanced Flossing Performance
Cordless Power Meets Professional Pressure
Despite its cordless design, the Waterpik WF-20 delivers 45–75 PSI of water pressure, powerful enough to remove debris, plaque, and bacteria between teeth and below the gumline. Its rechargeable lithium-ion battery provides consistent performance without losing power as it drains.
Clinically Proven Results
Waterpik is the first water flosser brand to earn the ADA Seal of Acceptance, confirming that its devices effectively reduce plaque and improve gum health. The WF-20 continues this legacy, helping users achieve healthier gums and fresher breath in just one minute per day.
