Waterpik Aquarius vs Ultra Plus: Which Countertop Water Flosser Is Right for You?

Choosing the right countertop water flosser can feel overwhelming, especially when you're deciding between two popular Waterpik models: the Aquarius and the Ultra Plus. Both are designed to improve your oral hygiene by removing plaque and debris, but they have distinct features that cater to different needs.

In this comparison, we'll break down the Aquarius and Ultra Plus side by side, examining their design, performance, and value. By the end, you'll know which one is the best fit for your bathroom counter and your smile.

Design and Build: Aquarius vs Ultra Plus

The Waterpik Aquarius (often referred to as WP-660) is known for its sleek, modern design with a digital display and a comfortable, ergonomic handle. It comes in a variety of colors, including the Modern Gray Aquarius Water Flosser – Gray (WP-667) and the White Aquarius Professional Water Flosser – White (WP-670). The Aquarius features a 360-degree rotating tip, a large 90-second water reservoir, and a quiet operation that many users appreciate.

The Ultra Plus (WF-150) has a more traditional look with a simple dial control and a slightly smaller footprint. It also offers a 360-degree rotation and a 90-second reservoir, but it lacks the digital display and some of the advanced pressure settings found on the Aquarius. The Ultra Plus is often considered a more budget-friendly option, but it still delivers the core water flossing benefits.

• Aquarius: Digital display, multiple pressure settings (10), sleek modern look
• Ultra Plus: Dial control, fewer pressure settings (6), compact design

Performance and Features: What Matters Most

When it comes to performance, both the Aquarius and Ultra Plus use Waterpik's proven pulsation technology to remove up to 99.9% of plaque. However, the Aquarius offers a wider range of pressure settings—10 in total—compared to the Ultra Plus's 6. This makes the Aquarius more customizable, which is beneficial for users with sensitive gums or specific oral care needs.

The Aquarius also includes a built-in timer and a pause button, which are handy for ensuring you floss for the recommended two minutes. The Ultra Plus, while simpler, still provides effective cleaning and is a reliable choice for those who prefer a no-frills approach. Both models come with multiple tips to accommodate different users, such as orthodontic, periodontal, and tongue cleaner tips.

• Pressure settings: Aquarius (10) vs Ultra Plus (6)
• Timer and pause: Aquarius yes, Ultra Plus no
• Tips included: both include standard, orthodontic, periodontal, and tongue cleaner tips

Ease of Use and Maintenance

Both models are designed for easy daily use. The Aquarius's digital controls make it simple to select your preferred pressure and pulse mode, while the Ultra Plus's dial is straightforward and intuitive. The water reservoirs are removable for easy cleaning, and both models have a covered storage compartment for tips, keeping your counter tidy.

Maintenance is similar for both: you'll want to clean the reservoir and tip regularly to prevent mineral buildup. The Aquarius's digital display also shows when it's time to replace the tips, a feature the Ultra Plus lacks. For families, the Aquarius offers a shared-use feature with multiple color-coded tips, making it easy for everyone to find their own.

• Tip replacement reminder on Aquarius
• Both have removable reservoirs and tip storage
• Color-coded tips available for multiple users

Price and Value: Which Offers Better Bang for Your Buck?

The Ultra Plus is typically priced lower than the Aquarius, making it an attractive option for those on a budget. However, the Aquarius's additional features—such as the digital display, more pressure settings, and timer—justify the higher price for many users. If you value customization and convenience, the Aquarius is worth the investment.

Considering the long-term benefits of improved oral health, both models offer excellent value. The Aquarius, with its advanced features, is often recommended for users with specific dental concerns, while the Ultra Plus is a great entry-level choice. When comparing, also consider the availability of replacement parts and the warranty, which are similar for both.

• Ultra Plus: more affordable, essential features
• Aquarius: premium features, better for sensitive gums and precise control

Other Countertop Options to Consider

If you're exploring other Waterpik countertop models, the Evolution Water Flosser – White (WF-33W010) offers a middle ground with a sleek design and 10 pressure settings, similar to the Aquarius. The Promax Water Flosser – White (WF-23W010) is another option with a larger reservoir and an ergonomic handle, ideal for those who want a bit more water capacity.

For a more compact choice, the Sidekick Water Flosser, Black with Copper – Black (WF-04CD012-3) is a travel-friendly countertop model, though it has a smaller reservoir. Each model has its own strengths, so consider your priorities—whether it's pressure control, design, or portability—when making your decision.

• Evolution: 10 pressure settings, modern look
• Promax: larger reservoir, comfortable grip
• Sidekick: compact, great for travel

Ultimately, the choice between the Waterpik Aquarius and Ultra Plus comes down to your personal preferences and budget. If you want advanced features like a digital display and more pressure settings, the Aquarius is the way to go. If you prefer a simpler, more affordable option, the Ultra Plus won't disappoint. Whichever you choose, you'll be investing in a healthier smile. Explore the Waterpik Aquarius to see if it's the right fit for you.
