Summary
A corded countertop water flosser sold under one name across many colorways and models, with ten pressure settings and a three-year warranty. Check which sub-model and which tips you are buying, because the Aquarius versions do not ship the same bundle.
Strengths
- Independent testers rank its cleaning with the higher-ranked countertop flossers.
- The Hydro-Pulse Massage mode is the only massage setting among Wirecutter’s countertop picks.
- Onboard storage for two tips, useful for households sharing one unit.
- The 22 oz reservoir is wide, removable and dishwasher-safe.
- Ten pressure settings plus a three-year warranty.
- Simple to run: no battery, no charging cycle, no app.
Weaknesses
- It must stay plugged in, so you need an outlet near the sink.
- It takes up more counter space than the smaller countertop models.
- The hose measures about 33 in, an inch shorter than some rivals.
- Reports of units breaking down or growing mold are more common than reviewers would like.
- Descaling is required every 1 to 3 months.
- Only two of the seven tips have onboard storage.

Full research notes and sources
Which model this is
The Aquarius is not one product. It is a family that shares a chassis: WP-660 white, WP-662 black, WP-663 blue and WP-667 gray at $99.99 list, plus the WP-670 and its Designer colorways at $109.99. Waterpik scopes the handle and reservoir replacements to the WP-660 and WP-670 series, which confirms the shared parts.
The listing referenced here carries ASIN B0D2VP85YP. Confirm the exact sub-model from its title, because the family spans many versions.
Tips and what ships in the box
The seven-tip bundle differs by version, and the manual warns that not all tips ship with all models. Base colorways ship four Precision tips plus Orthodontic, Plaque Seeker and Pik Pocket, with no toothbrush tip. The WP-670 Professional ships three Precision tips plus Orthodontic, Plaque Seeker, Pik Pocket and a toothbrush tip. Marketplace listings mix these up, so read the title rather than the name.
Cleaning, parts and running costs
This is a maintenance machine. The manual calls for descaling the internal parts with two tablespoons of white vinegar in a full reservoir of warm water every one to three months, because hard-water deposits can hinder performance. Orthodontic and Pik Pocket tips are rated for replacement about every three months, and Classic Jet and Tongue Cleaner tips about every six months.
Waterpik sells a handle-and-hose assembly for the WP-660 and WP-670 series at $19.99 and a replacement reservoir at $14.99. It also sells replacement tips and a tip storage case. The company states it does not guarantee that parts will stay available, so treat repairs as a real but best-effort channel.
Is it worth it?
At or below the $59.99 street price Consumer Reports lists, the Aquarius is a strong buy: cleaning that matches the higher-ranked countertop units, ten settings, a massage mode, onboard tip storage and a three-year warranty. Near $80 it still makes sense for anyone who does not need cordless operation. Close to the $99.99 list price the calculus shifts, because the Waterpik Ion Professional is a $100 machine that is smaller, easier to clean, has a longer hose and a cordless charging base. Above list price there is no measured advantage to pay for.
