The Waterpik Aquarius WP-662 delivers a well-rounded at-home dental cleaning experience with a thoughtfully engineered setup. Its 10 pressure settings offer a customizable clean, accommodating everything from gentle gum care to intense debris removal. A standout feature is the Hydro-Pulse Massage Mode, which provides additional stimulation to improve gum circulation. The unit’s built-in 1-minute timer with a 30-second pacer helps guide thorough and even flossing across all mouth areas.
The 22 oz reservoir supports over 90 seconds of uninterrupted use, while the 360-degree rotating tip ensures access to hard-to-reach areas, particularly behind molars and around orthodontic appliances. The inclusion of 7 tips - including classic jet, plaque seeker, and orthodontic styles - adds versatility for different users or oral care routines.
Build quality feels solid, with improvements like a spring-loaded valve system and an intuitive on/off switch on the handle. However, the device is noticeably loud during operation and requires a fair amount of counter space, making it less ideal for compact bathrooms. There are also minor complaints about tip storage limitations and crevices that are difficult to clean, which can potentially harbor mold if not maintained properly.
