The short answer

Waterpik ION Professional (WF-12) comes out ahead by a narrow margin (4.3 vs 4.5). The gap is mostly about buyers who want countertop-level power and capacity without a cord, and do not mind recharging every few weeks — read the strengths below before deciding.

Ranked #3 in Best Water Flossers

Waterpik Cordless Advanced 2.0 (WP-580)

4.3

1 sourceall derived$69.99as of Aug 1

The Waterpik Cordless Advanced 2.0 WP-580 is the travel and shower specialist: a slim, IPX7-waterproof handheld that Waterpik and reviewers call the most ergonomic in its cordless line. It charges fast over a magnetic USB connector, lasts up to four weeks, and ships with a travel bag and leak plug. MedGrade scores it 88/100. The 7 oz reservoir means frequent refills and there are only three pressure settings, so treat it as a portability pick rather than a full-time countertop replacement.

Strengths

— The most ergonomic handheld in Waterpik's cordless line, built for travel and the shower
— IPX7 fully waterproof for confident in-shower use
— Rapid magnetic USB charging reaches full in about 4 hours, lasting up to 4 weeks

Watch-outs

— Small 7 oz reservoir gives only about 45 seconds per fill - frequent refills
— Just three pressure settings (45-75 PSI), narrower than countertop units
— Only four tips included, fewer than the seven on countertop Waterpiks

Higher ratedRanked #1 in Best Water Flossers

Waterpik ION Professional (WF-12)

4.5

1 sourceall derived$99.99as of Aug 1

The Waterpik ION Professional WF-12 is essentially the Aquarius's performance in a cordless body. It keeps the full 10-100 PSI pressure range, a large reservoir good for 90-plus seconds of flossing, and seven tips, all running on a rechargeable battery that lasts up to four weeks per charge. MedGrade scored it the highest of any flosser at 94/100. It costs more than the Aquarius and the battery may fade over time, but it is the best pick for full power without a cord.

Strengths

— Full countertop power in a cordless body - 10 settings and a 22 oz-class reservoir
— Maintains the 10-100 PSI range and 1,300-1,400 pulses per minute of a corded unit
— Rechargeable lithium-ion battery lasts up to 4 weeks per charge

Watch-outs

— Premium price for a cordless unit
— Some owners report battery life shortening after 8-12 months
— Taller, top-heavy design versus a handheld travel flosser

How they stack up

Waterpik Cordless Advanced 2.0 (WP-580)

The travel and shower pick - it is far more portable than the countertop Waterpik Aquarius WP-660 and the cordless-but-bulky Waterpik ION Professional WF-12, but its 7 oz tank and 3 settings trail both; it is more compact than the Philips Sonicare Power Flosser 3000 though it holds far less water, and it is a clear step up from the budget AquaSonic Aqua Flosser in build and pedigree.

Waterpik ION Professional (WF-12)

The cordless equivalent of the Waterpik Aquarius WP-660 - it keeps the full 10-setting pressure range and large reservoir but runs on a battery, so it beats the small-tank Waterpik Cordless Advanced 2.0 WP-580 and the 3-setting Philips Sonicare Power Flosser 3000 on capacity and power, and outclasses the budget AquaSonic Aqua Flosser, at the cost of occasional recharging the corded Aquarius never needs.
