If you're shopping for a countertop water flosser, you've likely seen the Waterpik Ultra Plus. It's positioned as a step up from the classic Aquarius, but is it truly worth the extra cost? In this review, we'll break down the Ultra Plus's features, performance, and value to help you decide if it deserves a spot on your bathroom counter.
The Ultra Plus (model WF-150) is designed for those who want more control and convenience. With multiple pressure settings, a larger water reservoir, and enhanced tip storage, it aims to deliver a superior cleaning experience. But does it live up to the hype? Let's find out.
Key Features of the Waterpik Ultra Plus
The Waterpik Ultra Plus comes packed with features that set it apart from entry-level models. It offers 10 pressure settings, ranging from gentle to extra-strong, allowing you to customize your cleaning intensity. The 22-ounce reservoir holds enough water for a thorough 90-second flossing session, so you won't need to refill mid-brushing.
Another standout feature is the built-in tip storage compartment. The Ultra Plus includes a covered storage area that holds up to 7 tips, keeping them clean and organized. The unit also features a massage mode for gum stimulation, a handy on/off water control on the handle, and a 3-year limited warranty for peace of mind.

Performance and Ease of Use
In our testing, the Ultra Plus delivered a powerful yet comfortable clean. The 10 pressure settings range from a gentle 10 psi to a robust 100 psi, making it suitable for sensitive gums and deep cleaning alike. The massage mode is particularly effective for stimulating gum tissue, which can help improve circulation and overall oral health.
The handle is ergonomic and features a convenient pause button on the handle, so you can easily stop the flow without turning off the unit. The rotating tip allows for easy maneuvering around the mouth, and the 3-foot hose provides ample reach. The unit itself is compact and stable, taking up minimal counter space.
- Pressure range: 10-100 psi
- Ergonomic handle with pause button
- 360-degree rotating tip for easy access
- Compact footprint fits most countertops
Waterpik Ultra Plus vs. Aquarius: Which Is Better?
The most common comparison is between the Ultra Plus and the Aquarius. Both are countertop models with similar pressure ranges, but the Ultra Plus offers a few upgrades. The Ultra Plus has a larger reservoir (22 oz vs. 20 oz), built-in tip storage, and a massage mode. The Aquarius, on the other hand, is often more affordable and comes in a variety of colors.
If you value extra storage and the massage feature, the Ultra Plus is worth the upgrade. However, if you're on a budget and don't need those extras, the Aquarius remains a solid choice. For a detailed comparison, you might also consider the Classic Blue Aquarius Water Flosser – Blue (WP-663), which offers similar performance at a lower price point.

- Ultra Plus: larger reservoir, tip storage, massage mode
- Aquarius: more color options, typically lower price
- Both offer 10 pressure settings and 90-second capacity
Is the Ultra Plus Worth the Upgrade?
The answer depends on your needs. If you're upgrading from a basic flosser, the Ultra Plus offers significant improvements in customization and convenience. The massage mode is a unique feature that can benefit those with gum issues, and the tip storage is a practical addition for keeping your bathroom tidy.
However, if you already own a reliable countertop model like the Aquarius, the upgrade might not be necessary unless you specifically want the extra features. For those who travel frequently, a cordless option like the ION Professional Cordless Water Flosser – White (WF-12CD020-1) might be more suitable, but for home use, the Ultra Plus is a top contender.

- Ideal for users seeking advanced features
- Massage mode is great for gum health
- Consider cordless options if portability is a priority
In summary, the Waterpik Ultra Plus is a feature-rich countertop water flosser that delivers excellent performance and convenience. While it may cost more than the Aquarius, the added benefits of a larger reservoir, tip storage, and massage mode make it a worthwhile investment for those who want the best.
