String floss works, but most people do not use it correctly, often do not use it at all, and find it awkward enough to skip on busy mornings. The Waterpik Aquarius Water Flosser offers a different approach, using a pressurised stream of water to clean between teeth and along the gumline in a way that is faster, easier, and clinically proven to be more effective than string floss for improving gum health.
What Is the Waterpik Aquarius WP-662?
The Waterpik Aquarius is a countertop electric water flosser designed for daily dental care at home. It uses a combination of water pressure and pulsation to remove plaque and debris from between teeth, around braces, implants, crowns, and below the gumline. It is ADA accepted, meaning the American Dental Association has reviewed and accepted it for safety and effectiveness, and it is the number one water flosser brand recommended by dental professionals.

How Well Does It Actually Clean?
The clinical evidence behind this product is straightforward. The Waterpik Aquarius removes up to 99.9% of plaque bacteria from treated areas and is clinically proven to be up to twice as effective as string floss for removing bacterial plaque and improving gum health. For people with braces, implants, crowns, bridges, or deep periodontal pockets, water flossing reaches areas that string floss and toothbrushes simply cannot access effectively. The 360-degree rotating tip is a practical detail that makes a real difference. Back teeth and hard-to-reach areas are where plaque typically builds up unchecked, and the rotating handle makes it considerably easier to direct the water stream exactly where it needs to go.
The 10 Pressure Settings
This is one of the most practical features for new users. Starting on a lower pressure setting allows the gums to adjust gradually, which is important for anyone whose gums are sensitive or not accustomed to water flossing. As comfort increases, pressure can be raised for a deeper clean. The range from setting one to ten is wide enough to suit everyone from first-time users to those who have been water flossing for years.
Seven Tips for Different Needs
The WP-662 comes with seven tips in the box, which is more than most comparable models include. The Classic Jet Tip handles general everyday flossing. The Orthodontic Tip is designed specifically for braces. The Plaque Seeker Tip targets implants, crowns, and bridges. The Tongue Cleaner and Toothbrush Tips extend the usefulness of the device beyond just flossing. Having all of these included means families with different dental needs can share one machine without anyone needing to buy extra accessories.
The Built-In Timer
The one-minute timer with a 30-second pacer is a small but useful feature. Many people rush through oral care routines, and the pacer signals when it is time to switch sides of the mouth, ensuring thorough coverage across the full routine rather than spending most of the time in one area.

Is It Worth It?
Ranked number three in Power Dental Flossers on Amazon and sitting in the top 1,000 across all Health and Household products, the Waterpik Aquarius has the kind of sales volume and review depth that reflects years of consistent buyer satisfaction rather than a short-term surge. For anyone serious about their gum health or managing a dental condition that requires more thorough cleaning, it is one of the most well-supported and clinically backed options available in the category.
Final Verdict
The Waterpik Aquarius WP-662 makes daily flossing easier, faster, and more effective than string floss for most people. The combination of adjustable pressure, seven included tips, ADA acceptance, and a generous three-year warranty makes it a practical long-term investment in dental health rather than a gadget that collects dust after a week.
