Achieving optimal oral hygiene extends beyond just brushing; it demands a comprehensive approach to target plaque and debris lurking where toothbrushes can’t reach. For years, dental professionals have emphasized the importance of interdental cleaning, and for many, traditional string floss can be cumbersome or insufficient. Enter the Waterpik WP-660 Aquarius Water Flosser, a revolutionary device designed to elevate your daily routine and deliver a noticeably cleaner, healthier mouth. This guide will explore everything you need to know about this highly acclaimed water flosser, from its advanced features to practical usage tips, ensuring you make an informed decision for your dental health.

Water Flosser: A Comprehensive Oral Care Solution
What is a Water Flosser and How Does it Work?
Bảng trống.A water flosser, also known as an oral irrigator, is a dental device that directs a stream of pulsating water between your teeth and below the gumline. Unlike string floss that physically scrapes, the Waterpik Aquarius WP-660 utilizes a powerful, yet gentle, hydraulic action to dislodge food particles, plaque, and bacteria. This continuous stream penetrates hard-to-reach areas, effectively rinsing away harmful substances that contribute to cavities, gum disease, and bad breath. It’s like a mini pressure washer for your mouth, providing a deep clean without the harshness often associated with manual flossing.
Benefits Over Traditional Flossing
The advantages of incorporating a water flosser like the Waterpik Aquarius WP-660 into your oral care routine are significant. Clinical studies demonstrate that water flossers are remarkably effective, removing up to 99.9% of plaque from treated areas and proving up to 50% more effective than traditional string floss for improving gum health. This makes it an invaluable tool for individuals seeking superior plaque reduction and healthier gums. Moreover, for those with braces, implants, crowns, or bridges, water flossers offer a far gentler and more efficient way to clean around dental work, reducing irritation and ensuring thorough hygiene. The American Dental Association (ADA) has even recognized Waterpik products for their effectiveness, offering an extra layer of reassurance regarding their quality and performance.

Design and Build Quality
The Waterpik WP-660 Aquarius boasts a sleek and compact countertop design, making it a stylish addition to any bathroom without consuming excessive space. Standing taller than it is wide, its footprint is relatively small. The unit features a durable plastic construction, with a matt finish available in various colors to complement your decor. The clear, removable water tank simplifies refilling and cleaning. While it is a corded model requiring a power outlet, the generous 4.5-foot power adapter and 3.2-foot hose offer ample reach. Regarding operation, the WP-660 produces a noise level of around 72 decibels, which is generally considered average for a countertop water flosser.
Choosing the Right Water Flosser: Why the WP-660 Stands Out
Navigating the array of water flosser options can be daunting. The Waterpik WP-660 Aquarius distinguishes itself through its blend of performance, features, and value, often being compared to other popular models.
Comparison with Waterpik Ultra (WP-100)
When comparing the Waterpik WP-660 Aquarius to the older Waterpik Ultra WP-100, several key distinctions emerge. While both deliver effective cleaning, the Aquarius offers several enhancements: a convenient on/off slider switch directly on the handle (compared to the Ultra’s push button), the beneficial massage mode, an LED function indicator, and a built-in timer/pacer. The WP-660 also comes with 7 flossing tips, one more than the Ultra’s 6. Although the Ultra provides slightly more tip storage and a wider range of color options in some variants, the Aquarius is generally praised for its more modern design, improved user interface, and overall enhanced functionality.
Comparison with other Aquarius Models (WP-662, WP-663, WP-667, WP-670)
Waterpik offers several models under the “Aquarius” name, such as the WP-662, WP-663, WP-667, and the WP-670 (“Professional” or “Designer Series”). Fundamentally, these models share the same core technology, including identical pressure settings, water tank capacity, and pulse rates. The primary differences often lie in aesthetics, such as color options, specific accent finishes (e.g., chrome accents on the WP-670 Professional), and sometimes minor variations in the included tip lineup or a travel case for tips. The WP-660 is typically the base model, offering the full range of performance and key features at the most accessible price point, making it an excellent value choice without compromising on cleaning efficacy.
Countertop vs. Cordless Water Flossers
The Waterpik WP-660 Aquarius is a countertop model, designed for stationary use in your bathroom. Countertop units generally offer superior performance compared to their cordless counterparts. They typically provide a wider range of pressure settings (like the WP-660’s 10 settings), larger water reservoirs for extended use, and more consistent water pressure. While cordless models offer portability and are great for travel or smaller spaces without an outlet, they often have smaller tanks, fewer pressure options, and may require more frequent recharging. For a powerful, consistent, and comprehensive daily oral care solution at home, a countertop model like the WP-660 Aquarius is the preferred choice.
Who Benefits Most from the Waterpik WP-660 Aquarius?
The Waterpik WP-660 Aquarius is a versatile tool that can significantly enhance the oral health of various individuals.
- Individuals Seeking Superior Plaque Removal and Gum Health: With its clinically proven ability to remove up to 99.9% of plaque and improve gum health, anyone aiming for a deeper, more effective clean than brushing alone will benefit.
- Those with Braces, Implants, Crowns, Bridges, or Retainers: The specialized Orthodontic and Plaque Seeker tips make cleaning around these dental appliances incredibly easy and effective, preventing food traps and reducing the risk of inflammation or decay.
- People with Periodontal Pockets or Sensitive Gums: The Pik Pocket tip is designed for gentle, targeted cleaning below the gumline, while the 10 pressure settings and massage mode allow for a customized, comfortable experience, even for sensitive gums.
- Users Who Struggle with Traditional String Floss: If you find string flossing difficult, time-consuming, or uncomfortable, the Waterpik Aquarius provides a user-friendly and highly effective alternative that many find easier to incorporate into their daily routine.

How to Use Your Waterpik WP-660 Aquarius Effectively
Maximizing the benefits of your Waterpik WP-660 Aquarius involves a simple, yet effective, technique. Proper usage ensures you achieve the best possible results and maintain optimal oral hygiene.
Step-by-Step Guide
- Fill the Reservoir: Remove the reservoir and fill it with lukewarm water. You can also add a small amount of mouthwash for an extra boost of freshness, but always rinse the unit with plain water afterward.
- Select and Attach Tip: Choose the appropriate tip for your needs and firmly insert it into the handle until it clicks into place.
- Prepare for Flossing: Lean over the sink to allow water to drain, and place the tip into your mouth. Keep your lips slightly closed to prevent splashing, but allow water to flow from your mouth into the sink.
- Turn On and Adjust Pressure: Power on the unit and select your desired pressure setting. If you’re a first-time user, always start with the lowest pressure (setting 1) and gradually increase it as your gums become accustomed to the sensation.
- Begin Flossing: Direct the water stream at a 90-degree angle to your gumline, starting with your back teeth. Work your way around your mouth, pausing briefly between each tooth, and cleaning both the inner and outer surfaces of your teeth and gums. The integrated pacer will signal you to move to different quadrants of your mouth.
- Switch Off: Once you’ve completed flossing, turn off the water flow using the slider switch on the handle, then power off the main unit. Empty any remaining water from the reservoir.
Tips for Optimal Results
- Use Warm Water: Cold water can be shocking to sensitive teeth and gums. Lukewarm water provides a more comfortable experience.
- Lean Over the Sink: This simple step is crucial to prevent splashing and messes, especially when you are first getting used to the device.
- Regular Use: For the most significant improvements in oral health, use your Waterpik Aquarius at least once daily, preferably after brushing. Consistency is key to removing daily plaque buildup.
- Utilize the Pacer and Massage Mode: Let the 30-second pacer guide you for even cleaning, and occasionally use the massage mode to stimulate your gums.
- Replace Tips Regularly: To ensure maximum effectiveness and hygiene, replace your Waterpik tips every 3 to 6 months.
Maintenance and Longevity of Your Waterpik WP-660
Proper care and maintenance will significantly extend the lifespan of your Waterpik WP-660 Aquarius and ensure it continues to perform optimally.
Cleaning the Reservoir and Unit
To prevent mineral buildup and mold, it’s essential to clean your water flosser regularly. The removable reservoir can be washed with warm, soapy water. For a deeper clean, you can use a solution of white vinegar and water to flush the system periodically. After each use, it’s advisable to empty any remaining water from the tank and allow it to air dry. Regularly wipe down the exterior of the unit with a damp cloth to keep it clean and hygienic.
Replacing Tips and Common Issues
Waterpik tips are designed for effective performance over a limited period. It is recommended to replace them every three to six months, or sooner if bristles on orthodontic or toothbrush tips show wear. While the WP-660 Aquarius features an improved leak-resistant reservoir, some users occasionally report minor leaks from older units or if the reservoir isn’t seated correctly. Ensure the reservoir is properly aligned and consider a diluted vinegar flush if you notice reduced water pressure, which might indicate mineral buildup in the tubing. The plastic tubing connecting the handle to the unit is durable but can show wear over extended use; if it breaks, replacing the entire unit might be more practical than attempting a repair.
