Are you truly achieving the optimal oral hygiene you deserve with just brushing and traditional string floss? Many people overlook the significant impact that advanced tools can have on their gum health and overall dental cleanliness. The Waterpik Aquarius WP-660 Water Flosser stands out as a powerful solution, designed to reach areas brushing and string floss often miss, providing a superior clean and promoting healthier gums. This article delves into everything you need to know about the Waterpik Aquarius WP-660, from its innovative features to practical usage tips, helping you unlock a truly refreshed and radiant smile.

What is a Water Flosser? Why You Need It?
A water flosser, also known as an oral irrigator, is a device that uses a stream of pulsating water to remove food particles, plaque, and bacteria from between teeth and below the gumline. Unlike traditional string floss, which can be challenging to maneuver and sometimes irritating to gums, a water flosser offers a gentle yet highly effective alternative. The pulsating water not only cleans but also stimulates gum tissue, improving circulation and overall gum health.
The Waterpik Aquarius WP-660 is a prime example of this technology, engineered to deliver a comprehensive clean. Clinical studies have consistently shown water flossers to be more effective than string floss for reducing plaque and gingivitis. Waterpik, as the #1 recommended water flosser brand, has earned the American Dental Association (ADA) Seal of Acceptance, affirming its safety and effectiveness in contributing to good oral hygiene. Integrating a water flosser like the WP-660 into your daily routine can lead to noticeably cleaner teeth and healthier gums, creating a foundation for a vibrant smile and preventing common dental issues.
Introducing the Waterpik Aquarius WP-660
The Waterpik Aquarius WP-660 is a professional-grade countertop water flosser renowned for its blend of power, versatility, and user-friendly design. It’s designed to deliver an exceptional flossing experience, making it a favorite among dental professionals and users alike. This model is packed with features aimed at customizing your oral care routine to suit individual needs, from the most sensitive gums to advanced dental work.
At its core, the WP-660 utilizes a powerful motor to generate a consistent, pulsating stream of water. It offers an impressive range of 10 pressure settings, allowing you to fine-tune the intensity from a gentle 10 PSI up to a robust 100 PSI. This adaptability ensures that whether you’re new to water flossing or require a more intensive clean, the device can accommodate your comfort level. The Waterpik Aquarius WP-660 also boasts a large, removable 22-ounce (651 ml) water reservoir, providing 90 seconds of continuous flossing time, ample for a thorough cleaning without the need for constant refills. Its sleek, compact design makes it a stylish and functional addition to any bathroom countertop.
Types of Water Flossers: Focusing on Countertop Excellence
Water flossers primarily come in two types: countertop and cordless (portable) models. Each has its advantages, but the Waterpik Aquarius WP-660 firmly falls into the countertop category, a design chosen for its superior performance and feature set.
- Countertop Water Flossers (like the WP-660): These models typically offer higher pressure ranges, larger water reservoirs, and more advanced features. The WP-660 exemplifies this with its 10 pressure settings, dual modes, and comprehensive tip selection. The generous reservoir capacity eliminates the need for frequent refills during a cleaning session, ensuring a more consistent and uninterrupted experience. While they require an electrical outlet and a dedicated space on your bathroom counter, their robust performance and advanced capabilities make them ideal for daily, comprehensive oral care. The WP-660, in particular, balances a powerful motor with a relatively compact footprint, making it a top choice for those prioritizing effectiveness and convenience at home.
- Cordless Water Flossers: These are battery-operated and more portable, making them suitable for travel or smaller bathrooms without accessible power outlets. However, they generally have smaller reservoirs, fewer pressure settings, and less overall power compared to their countertop counterparts.
For an uncompromised daily cleaning routine, a countertop model like the Waterpik Aquarius WP-660 delivers the consistent power and functionality necessary for optimal oral health.
In-Depth Look at WP-660 Features
The Waterpik Aquarius WP-660 is distinguished by several key features that enhance its performance and user experience, making it a highly effective tool for comprehensive oral care.
Pressure Settings
With 10 adjustable pressure settings ranging from 10 to 100 PSI (0.689 to 6.895 Bar), the WP-660 allows for precise control over the water stream intensity. This customization is crucial, as it enables users to start with a gentle setting for sensitive gums and gradually increase the pressure as their gums adapt, ensuring a comfortable yet effective clean.
Dual Modes: Floss Mode and Hydro-Pulse Massage Mode
A standout feature of the Aquarius WP-660 is its innovative two-mode system:
- Floss Mode: Delivers the consistent high-pressure pulsations for maximum plaque removal and deep cleaning between teeth and below the gumline.
- Hydro-Pulse Massage Mode: Designed to enhance gum health by stimulating circulation. This unique pulsating massage effect can provide a soothing experience while gently promoting stronger, healthier gums.
Interchangeable Tips
The WP-660 comes with 7 specialized flossing tips, ensuring versatility for a variety of dental needs and multiple users:
- 3 Classic Jet Tips: For general daily cleaning.
- 1 Plaque Seeker Tip: Features three thin tufts of bristles to effectively remove plaque around implants, crowns, bridges, and retainers.
- 1 Orthodontic Tip: Designed with a tapered brush to access hard-to-reach plaque around orthodontic brackets and wires, making it ideal for individuals with braces.
- 1 Pik Pocket Tip: Engineered with a soft rubber tip for therapeutic delivery of water into periodontal pockets, crucial for those managing gum disease.
- 1 Tongue Cleaner Tip: Gently scrapes and flushes the tongue to remove bacteria that cause bad breath.
Reservoir Capacity & Pacer
The generous 22-ounce (651 ml) water reservoir provides 90 seconds of continuous flossing time, which is more than sufficient for a thorough cleaning without needing to stop and refill. Additionally, the built-in 1-minute timer and 30-second pacer guide you through the recommended flossing time for each quadrant of your mouth, ensuring you clean evenly and for the optimal duration.
Design & Usability
The WP-660 features a convenient On/Off slider switch directly on the handle, allowing for easy control of water flow without reaching for the main unit. The tip can rotate 360 degrees, providing easy access to all areas of the mouth. Its compact footprint means it fits comfortably on most bathroom countertops, and the removable reservoir simplifies refilling and cleaning.
Waterpik Aquarius WP-660 vs. Other Models
When considering a water flosser, it’s helpful to understand how the Waterpik Aquarius WP-660 compares to other popular models within the Waterpik lineup.
WP-660 vs. Waterpik Ultra (WP-100)
The Waterpik Ultra WP-100 has long been a classic, but the Aquarius WP-660 offers several notable enhancements:
- Massage Mode: The WP-660 includes the Hydro-Pulse Massage Mode, which the WP-100 lacks, providing an added benefit for gum stimulation.
- LED Function Indicator: The WP-660 is equipped with an LED display that visually indicates the current settings or mode, offering a more modern and user-friendly interface.
- Timer and Pacer: The Aquarius WP-660 integrates a 1-minute timer and 30-second pacer, guiding users through their flossing session for optimal coverage, a feature not present in the Ultra WP-100.
- Handle Switch: The WP-660 features an On/Off slider switch on the handle for easier water flow control, compared to a push button on the WP-100.
- Included Tips: The WP-660 typically comes with 7 tips, one more than the WP-100’s 6 tips, offering slightly greater versatility.
While both models deliver effective cleaning, the WP-660’s advanced features often make it the preferred choice for those seeking an enhanced oral care experience.
WP-660 vs. Other Waterpik Aquarius Models (WP-662, WP-663, WP-665, WP-667)
The Waterpik Aquarius series shares the same core performance technology across its models, including the 10 pressure settings and 90-second water capacity. The primary distinctions between the WP-660 and its siblings lie in aesthetics and minor feature additions:
- The WP-660 (White) and WP-665 (Orchid) are often considered the base models, offering excellent functionality in standard colors.
- Models like the WP-662 (Black) and WP-667 (Modern Gray) feature chrome accents or premium finishes, catering to users who prefer a more sophisticated bathroom aesthetic. The WP-662 also sometimes includes an LED display.
- The WP-663 (Blue) offers enhanced color options.
Essentially, while all Aquarius models deliver the same powerful flossing performance, the WP-660 stands out as a highly functional and often more affordable option for those who prioritize performance over purely aesthetic variations.
Who Should Use the Waterpik Aquarius WP-660?
The Waterpik Aquarius WP-660 is a versatile oral hygiene tool suitable for a wide range of individuals seeking to elevate their dental care.
- General Oral Hygiene Improvement: For anyone wanting a deeper, more effective clean than brushing and string floss alone can provide. Many users report a noticeably fresher mouth after incorporating water flossing into their routine.
- Individuals with Braces: The Orthodontic Tip is specifically designed to navigate around brackets and wires, making it significantly easier to remove food particles and plaque, which can be challenging with traditional methods.
- People with Dental Work: If you have implants, crowns, bridges, or retainers, the Plaque Seeker Tip helps to clean effectively around these restorations, preventing debris buildup and promoting their longevity.
- Those with Gum Sensitivity or Periodontal Issues: The adjustable pressure settings allow for a gentle yet thorough cleaning, while the Pik Pocket Tip can deliver therapeutic rinses into gum pockets, crucial for managing gingivitis and periodontal disease. The Hydro-Pulse Massage Mode can also be beneficial for stimulating gum health.

How to Use Your Waterpik Aquarius WP-660 Correctly
To maximize the benefits of your Waterpik Aquarius WP-660 and ensure a mess-free experience, follow these simple steps:
- Fill the Reservoir: Remove the reservoir, fill it with lukewarm water (or a dentist-recommended solution), and place it back on the base.
- Select a Tip: Choose the appropriate flossing tip for your needs and firmly insert it into the handle until it clicks.
- Adjust Pressure: Start with the lowest pressure setting (1 or 2) on the dial. You can gradually increase it over time as your gums become accustomed to the sensation.
- Position Yourself: Lean over the sink and place the tip in your mouth, aiming it at your gumline. Keep your lips slightly closed to prevent splashing, allowing water to flow into the sink.
- Turn On the Device: Power on the unit and use the slider switch on the handle to start the water flow.
- Floss Systematically: Start with your back teeth and work your way forward. Guide the tip along your gumline, pausing briefly between each tooth. Make sure to clean both the inside and outside surfaces of your teeth. The 30-second pacer will alert you to move to the next quadrant of your mouth, ensuring an even clean.
- Explore Modes: Use the Floss Mode for daily cleaning and switch to the Hydro-Pulse Massage Mode for gum stimulation, as desired.
- Empty and Rinse: Once finished, turn off the device, remove the tip, and empty any remaining water from the reservoir to prevent bacterial growth.
For optimal results, use your Waterpik Aquarius WP-660 once a day, preferably after brushing.
Cleaning and Maintenance of Your Waterpik Aquarius WP-660
Proper cleaning and maintenance are essential to ensure the longevity and hygienic operation of your Waterpik Aquarius WP-660. Neglecting these steps can lead to mineral buildup and reduced performance.
Daily Cleaning:
- Empty the Reservoir: After each use, empty any remaining water from the reservoir.
- Rinse the Reservoir: Rinse the reservoir with clean water. You can air dry it or wipe it down.
- Clean the Handle and Tip: Wipe the handle and the outside of the unit with a soft cloth. Remove the flossing tip and rinse it under warm water.
Weekly Cleaning (for descaling):
Over time, mineral deposits from water can build up inside the unit. To descale:
- Prepare Solution: Mix 2 tablespoons of white vinegar with 16 ounces (500 ml) of warm water in the reservoir.
- Run Half: Place the handle in the sink, turn the unit on to a medium setting, and run about half of the solution through the flosser until the reservoir is half empty.
- Soak: Turn off the unit and let the remaining solution sit in the reservoir for 20-30 minutes.
- Rinse Thoroughly: Run the remaining solution through the unit. Then, fill the reservoir with plain warm water and run it completely through the unit to rinse out any vinegar residue.
Troubleshooting Common Issues:
- Low Water Pressure: Ensure the reservoir is full and securely seated. Descale the unit if mineral buildup is suspected. Check if the tip is clogged.
- Leaking: Verify that the reservoir is correctly positioned and that there are no cracks.
- Noise: Some noise is normal due to the pump, but excessive noise might indicate a problem; refer to the user manual.
By consistently following these maintenance guidelines, your Waterpik Aquarius WP-660 will continue to provide effective and hygienic oral care for years to come.
