Our verdict
Where it wins
- Waterproof and rated for use in the shower, unlike the corded countertop models
- Waterpik rates the battery at up to 4 weeks per charge, so it does not need daily charging
- Global voltage compatible, unlike the countertop WP-660 which is North America only
- Small enough to pack for travel, with a travel bag and travel water plug included
Where it loses
- 7 oz reservoir holds about a third of the countertop WP-660's tank, so it needs refilling mid-session for some people
- Only 3 pressure settings versus 10 on the countertop model
- Replacement tips are a recurring cost: Waterpik says to swap them every 3 to 6 months, and a 4-pack runs about $10 to $13
- No wall adapter included with the magnetic USB-A charging cable
The Cordless Advanced 2.0 trades tank size and pressure range for portability: it is waterproof, works in the shower, and Waterpik rates the battery at a month between charges. That makes it the pick for travel or a cramped bathroom, but the small 7 oz reservoir and only 3 pressure settings make it less flexible than a countertop model for someone who wants a strong, adjustable stream. Buy it if portability and shower use matter more than tank size; buy the WP-660 instead if the flosser has a permanent spot near an outlet.

Common questions
How long does the battery last?
Waterpik rates the lithium-ion battery at up to 4 weeks of use per charge, and a full charge takes about 4 hours over the included magnetic USB-A cable. No wall adapter is included, so it needs a USB power source.
Can it be used in the shower?
Yes, Waterpik markets it as waterproof and designed for shower use, which the corded countertop models are not built for.
How often do the tips need replacing?
Waterpik recommends replacing tips every 3 to 6 months. A 4-pack of Precision tips typically costs about $10 to $13.
Does it prevent gum disease?
No single device prevents gum disease. Waterpik says the WP-580 removes up to 99.9% of plaque bacteria from treated areas in its own lab testing and cites clinical studies showing it outperforms string floss at reducing bleeding and plaque in study participants. Those are manufacturer-cited results, not a guarantee for any individual.
