The Waterpik Aquarius Water Flosser WP-663 is the gold standard in at-home dental water flossing. It carries the American Dental Association Seal of Acceptance. This open-box unit is a fantastic way to own a premium flosser at a below-retail price. Like-new condition — no scratches, scuffs, or signs of use are visible on the unit. Every accessory is present and accounted for in the original packaging.

The Aquarius flosser features ten pressure settings for a fully customized clean. Setting 1 is ultra-gentle, ideal for sensitive gums or first-time users. Setting 10 delivers maximum pressure for a deep, thorough clean. A dedicated Massage mode pulses water to stimulate gum tissue and improve circulation. The built-in timer and pacer pauses briefly at 30 seconds and again at 60 seconds. This helps you track your flossing time and cover every zone of your mouth. Dentists recommend at least one full minute of water flossing daily. The Aquarius makes hitting that target effortless and automatic.

PrecisionPulse technology is the engine behind the Aquarius flosser's cleaning power. It delivers a precise combination of water pressure and high-frequency pulsations. This dual action drives water deep between teeth and below the gumline. Traditional string floss cannot reach these areas effectively. Studies show Waterpik removes up to 99.9% of plaque bacteria from treated areas. It is up to 2x more effective than string floss for improving gum health. For braces wearers, it is up to 3x more effective than brushing and string flossing combined. The dental community consistently endorses Waterpik as the number one water flosser brand.

The large 22-ounce removable reservoir holds enough water for 90 or more seconds of continuous flossing. That means one full fill covers an entire flossing session without stopping to refill. The reservoir lifts out cleanly for easy filling and is top-rack dishwasher safe. The flossing wand is slim and maneuverable, making it easy to reach back molars. A convenient on/off water control switch sits right on the wand handle. The tip rotates a full 360 degrees with just one hand. This single-handed rotation lets you easily reach every corner of your mouth. The unit runs on 120V AC power and is designed for North American use.

Seven interchangeable tips make this flosser versatile for the whole family. Each family member can have their own color-coded tip for hygiene. The Classic Jet Tip handles everyday plaque removal and gum care. The Orthodontic Tip is engineered specifically for braces and retainers. The Plaque Seeker Tip targets dental work like implants, crowns, and bridges. The Tongue Cleaner removes odor-causing bacteria from the tongue's surface. The Pik Pocket Tip is designed for periodontal pockets and furcations. All seven tips store neatly in the onboard tip storage compartment on the unit. No loose accessories floating around your bathroom counter.

Waterpik backs the Aquarius with a 3-year limited manufacturer's warranty. Their Colorado-based customer support team is available to answer any questions.

Frequently Asked Questions

Question 1: Is the Waterpik Aquarius WP-663 truly in like-new condition?

Answer 1: This unit was returned to Amazon in open-box condition and graded A+ by our inspection team. Our graders examined every surface of the flosser and found no scratches, scuffs, or signs of prior use. The unit, wand, reservoir, and all seven tips are visually indistinguishable from a brand-new product.

Question 2: What tips and accessories are included with this listing?

Answer 2: All original accessories are present and complete. The package includes all 7 tips (Classic Jet Tip, Orthodontic Tip, Plaque Seeker Tip, Tongue Cleaner, Pik Pocket Tip, and two standard Classic Jet Tips), the tip storage case, the flossing wand, the 22 oz reservoir, the power cord, and the original manual. Nothing is missing from the factory configuration.

Question 3: Can the Waterpik Aquarius flosser be used with braces?

Answer 3: The Aquarius is an excellent choice for orthodontic patients with braces. The included Orthodontic Tip is specifically designed to clean around brackets, wires, and bands where toothbrushes and string floss struggle. Waterpik's own research shows the Aquarius is up to 3 times more effective at removing plaque around braces than brushing and string flossing alone. Many orthodontists recommend it as a standard part of braces care.

Question 4: Does the Waterpik Aquarius WP-663 work for people with implants or dental work?

Answer 4: The Aquarius is well suited for people with crowns, bridges, and dental implants. The included Plaque Seeker Tip is engineered to clean around implant hardware and other restorations. Research indicates the Aquarius is up to 2 times more effective than string floss for improving gum health around implants. Using a low-to-medium pressure setting when starting out is recommended to protect sensitive dental work.

Question 5: What is the reservoir capacity and how long does one fill last?

Answer 5: The removable reservoir holds 22 ounces of water, which provides over 90 seconds of continuous flossing time. That is more than enough for a complete session covering all teeth without refilling. The reservoir detaches easily for filling at the sink and is top-rack dishwasher safe for convenient cleaning. Measurement markings on the side make it easy to track water levels.
