Waterpik Aquarius Water Flosser (WP-660) vs Philips Sonicare Cordless Power Flosser 3000 (HX3826)
Which should you buy? Here's the honest call, pulled from our full The Best Water Flossers: What Actually Cleans Between Your Teeth comparison.
For most people the Waterpik Aquarius is the easy call: the big tank, wide pressure range and low daily fuss are exactly what keeps a flosser in your routine instead of a drawer. If counter space or travel matters more, the Philips Sonicare Cordless Power Flosser 3000 is the cordless to get, delivering the strongest-yet-gentle stream reviewers tested. The Cordless Advanced 2.0 is a fine niche pick for showers and trips if you can live with short runtime. Skip the Sonic-Fusion 2.0, buying a good toothbrush and flosser separately cleans just as well and costs less over time.
