Maintaining good oral hygiene is essential for a healthy lifestyle, and while traditional flossing plays an important role, many people find it tedious or ineffective. The Waterpik Aquarius Water Flosser WP-660 presents a modern solution to this problem. Designed for deep cleaning between teeth and along the gumline, this advanced water flosser combines convenience, performance, and clinically proven results. In this review, we’ll explore everything you need to know about the Waterpik Aquarius, from features and benefits to its strengths and limitations.
Design and Build Quality
The Waterpik Aquarius WP-660 features a sleek and compact design that fits easily on most bathroom countertops. It comes in a clean white finish that looks modern and professional. Despite its relatively small footprint, the unit includes a large 22-ounce water reservoir capable of delivering more than 90 seconds of flossing time per fill. The reservoir is removable and top-rack dishwasher safe, making it easy to clean and maintain.
The device includes a convenient on/off water switch on the handle and a 360-degree rotating tip that provides excellent maneuverability, even when targeting difficult-to-reach areas like the back molars. The build quality feels solid, and all components fit together snugly.
Key Features
One of the standout features of the Waterpik Aquarius is its 10 pressure settings, allowing users to customize water pressure from gentle cleaning to a more intense flossing experience. This makes it suitable for users with different sensitivity levels, including those with braces, implants, crowns, or sensitive gums.
The massage mode helps stimulate gum circulation, supporting gum health over time. A built-in timer/pacer pauses the water flow at 30-second and 1-minute intervals to help users track their flossing time and ensure thorough cleaning of all areas.
Included in the package are 7 flossing tips, designed to meet the needs of multiple users and various dental care requirements. These include:
-
3 Classic Jet Tips
-
1 Orthodontic Tip (ideal for braces)
-
1 Plaque Seeker Tip (for crowns and bridges)
-
1 Pik Pocket Tip (for periodontal pockets)
-
1 Toothbrush Tip
The device runs on 120VAC/60Hz, making it compatible for use in North America only.
Performance and Effectiveness
When it comes to performance, the Waterpik Aquarius delivers exceptional results. It uses PrecisionPulse™ technology that combines water pressure and pulsation to effectively remove plaque and debris. According to clinical studies, it removes up to 99.9% of plaque bacteria from treated areas, making it significantly more effective than traditional string flossing.
The water stream is powerful yet comfortable, and users can start on lower pressure settings before gradually increasing as they adjust. The device is especially helpful for users with braces or dental work, where string flossing is often inadequate or difficult.
Within just a few uses, many users report noticeable improvements in gum health, reduced bleeding, and an overall cleaner mouthfeel. The massage mode also adds a therapeutic benefit by promoting better blood flow in the gums.
Ease of Use
Using the Waterpik Aquarius is straightforward. Fill the water reservoir, choose your desired pressure setting, select the appropriate tip, and begin flossing. The ergonomic handle and rotating tip make it easy to direct the stream exactly where it’s needed. The built-in timer is a subtle but useful feature that encourages complete and consistent flossing.
Cleaning the device is equally simple. Most removable parts are dishwasher safe, and the unit can be wiped down with a damp cloth after each use. Tip replacements are available and easy to install.
