Selecting the best Waterpik model is no easy task, considering there are so many to choose from. In addition to choice, you have different price ranges, and three types to ponder upon (counter, cordless and attachable water flossers).

But, you’ve made it to this page, so it is fair to say that you have narrowed down your search to Waterpik Aquarius and Ultra. Excellent choice!

We have tested each model extensively, because we like to avoid dental appointments as much as possible, and below you can find our results and reviews.

Main Differences

Waterpik Aquarius are Ultra are not only made from the same manufacturer, but they are also like twins when it comes to functionality and accessories.

Aquarius has ten pressure settings, seven Waterpik flossing tips, and 90 seconds of water capacity. At Dental Dorks we have tested and reviewed this model before and found that it definitely improves oral health by strengthening the gum line.

Waterpik Ultra also has ten pressure settings and 90 seconds of water capacity, but it only comes with six flossing tips. So far so good, you are only getting an extra flossing tip from the Aquarius, which is certainly not a game changer when it comes to oral hygiene.

Since the flow rate of water for both models is identical, you will get identical results when it comes to flossing. These two Waterpik products remove plaque and bacteria down to the deepest part of your teeth. They clean the gums gently and thoroughly as they remove all the excess dirt from it.

Aquarius and Ultra Differences

The Ultra is smaller and less noisy than Waterpik’s previous models. Whether we like to admit it or not, as electric floss users, we are disturbed by the noise that is produced by the gadgets we use and hold in our hands. So, this is convenient for those people who easily get annoyed or bothered by the littlest noises that may be produced by flossers.

Ultra has an improved design that features a covered reservoir with an in-lid tip storage compartment- with its ergonomic handle design, the user will find it very comfortable to hold, and pleasant to look at.

Aquarius features a compact and contemporary design, being Waterpik’s most updated and advanced flosser. The water flosser has a 1-minute timer and 30-second pacer, a finger-tip easy pressure control, and push-button power with a LED mode display which makes it convenient for the user

Whether the user prefers deep cleansing or gentle water pressure, the Ultra Water Flosser provides 10 modifiable water-pressure settings, giving you ideal control to choose whatever preference he/she has in mind.

Different Names, Same Results

Both models allow users to select a modified setting between 10 to 90 PSI with 1,400 pulses per minute. It allows both water flossers to reach the deepest pockets between your teeth and clean as much plaque and food debris as possible.

In addition, each model can be used at a lower water flow setting that allows for gentle cleaning and massaging of the gums.

Our research has more or less been similar to already clinically proven studies. Both the Aquarius and Ultra return the same positive results. They offer less intrusive flossing and if used twice a day with a mixture of water and mouthwash solution, can help reverse several oral diseases.

The verdict

Both units perform identically. They will also take identical space on your counter. The only difference is that the Ultra model comes equipped with one less flossing tip. It also appears to be slightly louder when working.

In terms of usability, the two Waterpiks are similar. They both have handles with ON/OFF button that allows for easy control and a steady hand.

Often times the Ultra is listed a bit cheaper than the Aquarius, so if this is the case, we would recommend you take advantage and save a few bucks.
