Waterpik Water Flossers Buying Guide

Waterpik's lineup covers countertop and cordless water flossers at multiple price points. Here is how to match the right model to your space, budget, and flossing habits.
Aquarius Professional — The Countertop Standard
The Aquarius WP-660 is Waterpik's most popular model and the one most dental offices recommend. It has 10 pressure settings (10-100 PSI), a 22-oz reservoir for 90 seconds of continuous use, and comes with 7 tips — classic jet, orthodontic for braces, periodontic for gum disease, tongue cleaner, and brush tips. The larger reservoir means most people can floss a full mouth without refilling. The countertop form factor makes it the least travel-friendly but the most reliable for daily home use.
Cordless Select — Best for Travel and Small Spaces
The Cordless Select (WP-560) has 3 pressure settings, a 7-oz reservoir, and charges via USB. The USB charging is the main upgrade over older cordless models that used AA batteries — significantly cheaper to run. The smaller reservoir means 45 seconds of use per fill, which is enough for one flossing session but requires refilling mid-mouth for very thorough flossing. Best for travel bags and apartment bathrooms without counter space.
ION Professional — Long Battery Life
The ION Professional (WP-670) is the premium cordless model — magnetic charging, 30-day battery life per charge, and 10 pressure settings in a countertop-free form. It bridges the gap between the compact Cordless Select and the full Aquarius without requiring a permanent countertop spot. The 9-oz reservoir is larger than the Cordless Select.
Shower Flosser
The Waterpik Shower Flosser (WP-072) attaches to any standard shower hose and uses water pressure from the shower head — no electricity, no charging, no reservoir. Pressure varies with your water pressure. The primary advantage is no maintenance; the trade-off is you can only floss in the shower and cannot control pressure as precisely as a powered model.

How We Analyze Products
We analyze Amazon review data — often thousands of reviews per product — to surface patterns
that individual buyers miss. Our process aggregates star ratings, review counts, and buyer
sentiment at scale, identifying which strengths and weaknesses appear consistently across
the largest review samples available.
Each product earned its placement through data: total review volume, average rating, and the
specific praise and complaints that repeat most often across buyers. No manufacturer paid for
placement on this page. Products appear here because buyers endorsed them at scale, not
because a company asked us to feature them.
We use AI to summarize review sentiment — not to fabricate opinions, but to condense what
thousands of buyers actually wrote into a readable format. The pros and cons you see reflect
the most common themes found in verified purchaser reviews, paraphrased for clarity. We do not
claim to have accessed Reddit, YouTube, or specific publications in generating these summaries.
Prices shown reflect Amazon pricing at the time this page was last generated. Click
