Product Overview

The Waterpik WP-660 Aquarius is a professional-grade countertop water flosser designed to deliver a powerful, yet customizable, stream of pulsating water to clean between teeth and below the gumline. It is engineered to remove plaque and food debris that traditional brushing and flossing might miss, promoting healthier gums and a cleaner mouth. The device features a sleek, compact design for a countertop model, a generous water reservoir, and a selection of specialized tips to cater to various oral care needs. Positioned as a comprehensive solution for improved oral health, the WP-660 integrates advanced features intended to offer a superior flossing experience.

Key Features

• 10 Pressure Settings: Offers a wide range of water pressure from 10 to 100 PSI, allowing users to customize the intensity from gentle cleaning to maximum plaque removal.
• 7 Water Flosser Tips Included: Comes with a versatile assortment of tips, including 3 Classic Jet Tips, 1 Plaque Seeker Tip (for implants/crowns), 1 Orthodontic Tip (for braces), 1 Pik Pocket Tip (for periodontal pockets), and 1 Toothbrush Tip. This variety enables tailored cleaning for specific dental needs.
• Massage Mode: In addition to the standard flossing mode, the Aquarius features a “Hydro-Pulse Massage Mode” which aims to stimulate gums, promoting circulation and overall gum health.
• 1-Minute Timer with 30-Second Pacer: A built-in timer signals when to move to the next quadrant of the mouth, ensuring a thorough and consistent cleaning of all areas, aligning with dentist-recommended flossing times.
• Large 22-Ounce Reservoir: Provides 90 seconds of water capacity, eliminating the need for frequent refills during a single cleaning session. The reservoir is also top-rack dishwasher safe for easy cleaning.
• Advanced Ergonomics: Features a swivel handle that allows for easy reach to all areas of the mouth and a convenient on/off water control on the handle itself.

Pros and Cons

Pros:

• Clinically Proven Effectiveness: Waterpik water flossers are widely recognized and clinically proven to be more effective than traditional string floss for reducing plaque, gingivitis, and gum bleeding.
• Superior for Specific Needs: Particularly beneficial for individuals with braces, implants, crowns, bridges, and periodontal pockets, where traditional flossing can be challenging or less effective.
• Customizable Cleaning: The 10 pressure settings and multiple tip options allow for a highly personalized and comfortable flossing experience for a broad spectrum of users.
• Improved Gum Health: Regular use is consistently reported by users to lead to healthier, less inflamed gums and fresher breath.
• Ease of Use: Many users find water flossing less cumbersome and more enjoyable than string flossing, potentially leading to better compliance with daily oral hygiene.
• Comprehensive Coverage: The 1-minute timer and 30-second pacer encourage thorough cleaning of the entire mouth.

Cons:

• Initial Learning Curve / Messiness: New users may experience some splashing or mess initially until they master the technique.
• Countertop Footprint: As a countertop model, it requires dedicated space on the bathroom counter and access to an electrical outlet.
• Noise Level: While not excessively loud, the device does produce a noticeable hum during operation, which might be a consideration for some.
• Not a Replacement for Brushing: While highly effective for interdental cleaning, it is designed to supplement, not replace, regular toothbrushing.
• Requires Water Refills: Though the reservoir is generous, it still requires filling with water before each use.

Who Should Buy This

• Individuals seeking advanced oral hygiene: For those committed to optimal dental health beyond basic brushing.
• Users with braces, implants, crowns, or bridges: The specialized tips and powerful water stream are highly effective at cleaning around orthodontics and dental work.
• People with sensitive gums or gum disease: The massage mode and customizable pressure settings can provide gentle yet effective cleaning to improve gum health.
• Anyone who struggles with traditional string flossing: If you find string flossing difficult, time-consuming, or ineffective, the Waterpik offers a user-friendly alternative.
• Families: With multiple tips included and an easy-to-use design, it can be a valuable addition to a family bathroom, allowing various members to benefit.

Who Should Avoid This

• Frequent travelers: As a countertop model, it is not designed for portability. A cordless water flosser would be a more suitable choice.
• Individuals with extremely limited counter space: While relatively compact for its class, it still occupies a footprint that might be too large for very small bathrooms.
• Budget-restricted buyers looking for the absolute cheapest option: While an excellent value, there are more basic, less feature-rich water flossers at lower price points.
• Those expecting a completely silent operation: Like most motorized appliances, it produces some operational noise.

Pricing Insight

The Waterpik WP-660 Aquarius typically sits in the mid-to-high price range for consumer-grade water flossers. Its pricing reflects its robust feature set, brand reputation, and clinical efficacy. While not the cheapest option on the market, it represents a strong value proposition given its durability, versatility with 7 tips, and the demonstrated improvements in oral health it can facilitate.
