Is the Waterpik Cordless Express as strong as a plug-in Waterpik?

No. It has two settings and runs on AA batteries, so its stream is gentler than corded models like the Aquarius. It suits light daily use and travel rather than deep-pressure cleaning.

How long does one fill last?

The reservoir holds about 30 seconds of water. Most users need to refill once or twice to finish a full clean.

Does it come with batteries and tips?

Yes. It ships with three AA batteries and two classic jet tips.

Can I use it in the shower?

Yes. It is waterproof and designed for shower use.

Is it a good choice for braces or implants?

It can help around braces, but its lower pressure and short run time make a corded Waterpik with a orthodontic tip a better fit for heavy plaque needs.

How often should I replace the tips?

Waterpik recommends changing tips every three to six months, or sooner if the tip looks worn.

What reviewers say

Owners treat the Cordless Express as a convenient travel and shower flosser. Many say it is gentler and less powerful than plug-in Waterpiks, and the short water capacity means refilling during a session. Most still find it useful for on-the-go gum care.

About the Waterpik Cordless Express Water Flosser WF-02

The Waterpik Cordless Express Water Flosser WF-02 is a battery-operated water flosser. It uses a combination of water pressure and pulsations to clean between teeth and below the gumline, removing bacteria and debris. It is intended to be used for about one minute a day.

It runs on 3 AA batteries, so no outlet is needed. The unit is waterproof and safe to use in the shower. It has an on/off switch and a dual pressure control system with 2 pressure settings. The reservoir holds 30 seconds of water and is clear, and the body has a satin finish.

Tips attach and release with a quick-release mechanism for easy changing. The flosser comes with 2 tips, including a classic jet tip for general use.
