Waterpik Cordless Advanced Review (2027)
In-depth review of the Waterpik Cordless Advanced WP-560: cordless freedom, shower use, and the trade-offs in 2027.
Waterpik Cordless Advanced WP-560
Full Waterpik performance without the cord or countertop.
Our verdict
The Cordless Advanced is the flosser people actually use. Its 1,450 pulses per minute match countertop cleaning power, waterproofing enables mess-free shower flossing, and freedom from outlets removes every excuse. The 45-second reservoir and 3 pressure settings are real compromises, but compliance beats specifications: the best flosser is the used one.
What we like
- Cordless and waterproof for shower use
- 3 pressure settings covering gentle to full cleaning
- 4 tips included with 360-degree tip rotation
- Rechargeable battery with no outlet needed at the sink
What to watch out for
- 7-ounce reservoir gives about 45 seconds, requiring refills for full routines
- Only 3 pressure settings versus 10 on the Aquarius
- Needs recharging every week or so with daily use
What owners report: Waterpik Cordless Advanced WP-560
Synthesized from recurring themes in long-term owner feedback.
Most praised
- Shower flossing with a waterproof cordless body turns a chore into an existing habit for owners
- Tip rotation helping reach back molars without contorting the hand is frequently mentioned
- Travelers praise leaving the countertop base at home without giving up real flossing
Common complaints
- The small reservoir often needs a refill to finish a careful routine
- Three settings feel limiting on days when gums want something in between
- Daily users find themselves recharging about weekly, which is easy to forget
Who it is for
Travelers, small-bathroom owners, shower flossers, and anyone whose countertop flosser gathers dust. Not for users who want maximum settings and reservoir.
Portability and shower use
Fully waterproof and cordless, the WP-560 works in the shower, where water flossing's mess problem disappears entirely. No outlet hunting, no counter footprint, no cord draped across the sink. For travel it packs easily and the rechargeable battery lasts about a week. This convenience is the product's entire thesis, and for the large group of people who own a countertop flosser they never use, it is the correct thesis.
Performance vs countertop
At 1,450 pulses per minute, cleaning power is genuinely comparable to the Aquarius. The compromises are 3 pressure settings instead of 10, which is enough for most (low, medium, high covers the adaptation curve), and a 7-ounce reservoir giving about 45 seconds. In practice that means one refill per full routine. The 360-degree rotating tip helps reach back teeth in the confined shower environment.
Battery and maintenance
The rechargeable battery needs weekly charging with daily use, so build it into the routine or face the dead-flosser morning. Four tips are included; the magnetic USB-style charging is simple. Rinse the reservoir after use to prevent biofilm, a step cordless users skip more often because the unit lives in the shower. Treat it like a toothbrush: rinse, shake dry, done.

Questions, answered
Is the Cordless Advanced as good as the Aquarius?
For cleaning power per pulse, yes. For versatility, no: fewer settings, smaller reservoir, fewer tips. Buy it for the use case (travel, shower, small bathroom), not as a strict upgrade.
Can it really be used in the shower?
Yes, it is fully waterproof and designed for it. Shower flossing contains the spray mess that puts many people off water flossers. Do not charge it wet; dry the contacts first.
How do I manage the small reservoir?
Floss the top teeth, refill (10 seconds), floss the bottom. The two-stage routine becomes automatic within a week. Some users keep a cup of water in the shower for quick refills.
