It's best suited for travelers or those seeking a potent yet compact flossing solution.

Waterpik Aquarius

4.7

1 source$94.4as of Oct 12

The Waterpik Aquarius (WP-660) is a mains-powered countertop water flosser with a 22-ounce reservoir, ten pressure settings from 10 to 100 PSI, a floss and a massage mode, and a 30-second pacer. Electric Teeth names it the best countertop water flosser available and praises its plaque removal, grippy pressure dial and rotating nozzle. Its reservations are the price, the seven included tips being more than most people will use, and noise of up to 72 decibels that it calls average rather than 'ultra quiet'.

Strengths

— Ten pressure settings from 10 to 100 PSI on a textured dial that Electric Teeth found easy to adjust
— 22-ounce (651ml) removable reservoir gave Electric Teeth about 90 seconds at the highest setting and 4 minutes 45 seconds at the lowest
— Pacer pauses the water at 30 and 60 seconds, and can be switched off

Watch-outs

— Electric Teeth lists the price as a con, describing it as a premium option at a $99.99 retail price
— Needs a power outlet: there is no battery, and the cord is about 4.5 feet long
— Up to 72 decibels in use, which Electric Teeth considers average rather than the 'ultra quiet' Waterpik claims

How they stack up

Oclean A10 AirPump Water Flosser

The Oclean A10 AirPump Water Flosser has a 45ml tank, far smaller than the 148 ml of the Waterpik Cordless Express or the 250ml of the Philips Sonicare Power Flosser 3000 Cordless. It has three cleaning modes to the Express's two pressure settings, and it recharges by Type-C cable and magnetic dock where the Express uses AA batteries. Its highest settings are very aggressive.

Waterpik Aquarius

The Waterpik Aquarius must stay plugged in, where the Waterpik ION Professional Water Flosser (WF-12) runs from a rechargeable battery. Electric Teeth, which reviewed both, makes the Aquarius its first choice for a countertop flosser and found its ridged rotating nozzle easier to turn than the ION's; the Aquarius holds 22 ounces of water against the ION Professional's 20.
