Advanced Water Flossing System

The Waterpik Aquarius WP-660 is a countertop water flosser designed for individuals and families seeking thorough interdental cleaning. It delivers 10 pressure settings and includes 7 specialised tips to address braces, implants, bridges, crowns and general gum care. The ADA Seal of Acceptance confirms safety and effectiveness for daily oral hygiene routines.

Quiet Corded Operation

The unit runs on 120VAC/60Hz North American mains power with a corded electric supply, so there is no battery to recharge. A removable 22-ounce (650 ml) reservoir provides 90-plus seconds of continuous flossing without refilling, and the top-rack dishwasher-safe reservoir simplifies cleaning. The 360-degree rotating tip and compact wand allow easy access to posterior teeth during regular use.

Sustained Flossing Performance

PrecisionPulse technology maintains consistent pressure and pulsation throughout the full reservoir cycle, removing up to 99.9 percent of plaque bacteria from treated areas. A built-in timer and pacer pause briefly at 30 seconds and one minute to guide thorough coverage without guessing. The massage mode adds gentle gum stimulation for users who prefer a softer, longer session.

Questions about this item

How do I install the Waterpik Aquarius WP-660 and what step is commonly missed?

Fill the 22 oz reservoir with warm water, click a tip into the handle until it locks, lean over the sink, aim at a 90-degree angle along the gumline, then press the on/off switch on the handle; many users forget to activate the handle switch after turning on the base unit.

What maintenance or replacement will the Waterpik Aquarius WP-660 need later?

Replace flossing tips every 3 to 6 months; clean the removable 22 oz reservoir on the top rack of a dishwasher periodically; wipe the handle and base with a damp cloth; descale the internal tubing with a vinegar solution if mineral build-up reduces pressure.

What limit appears first during sustained use of the Waterpik Aquarius WP-660?

The 22 oz reservoir provides 90+ seconds of continuous flossing before it must be refilled; the built-in timer/pacer pauses briefly at 30 seconds and 1 minute to signal quadrant changes and end of session.
