Waterpik Aquarius vs Waterpik Ultra

The Waterpik Ultra and the Waterpik Aquarius both come with big reputations. The Ultra has been referred to as the core staple in the Waterpik line and the Waterpik Aquarius has been branded the flagship device of Waterpik (view on Amazon). Both blow the competition out of the water, but how do they compare to each other?

Waterpik, Inc. has been a leader in personal oral healthcare products for over five decades. And there’s a reason why Waterpik has stood the test of time.  They manufacture products that are innovative with great features and benefits.

All Waterpik products have outstanding features that promote advanced oral hygiene. Although the Aquarius and Ultra may seem similar, there are marked differences that you should consider before purchasing in order to get the maximum benefit and avoid over-spending on unnecessary features.

In this Waterpik Aquarius vs Ultra Review, we will compare features side-by-side and hone in on exactly what each water flosser has to offer.

The Short Verdict

Side by side, the features of the two water flossers are very similar. However, the Waterpik Aquarius just has the edge over the Ultra in terms of features and appearance. It offers massage mode, which is great for anyone suffering with gum problems, and as the newer model, it looks more modern and sleek in your bathroom.

However, the Aquarius also usually comes with a slightly higher price tag so if you’re just on the hunt for a good quality water flosser that gets the job done, the Ultra might just be for you.

Let’s take a more close-up look at where the features differ and why they are important.

Common Features of the Aquarius and Ultra



Both the Aquarius and Ultra are countertop water flossers. This means that instead of being hand-held, they have a larger body and reservoir that should sit on your countertop.

Countertop water flossers have a number of benefits over their cordless, handheld counterparts including:

  • More powerful
  • Larger reservoir range
  • Extra features

Pressure settings

Both of these Waterpiks have an excellent range of pressure available with 10 different settings ranging from 10–100psi. 100psi is very near the top end of pressure for water flossers and can achieve the most thorough clean.

The lower settings allow for a tailored experience and are especially good for those with gum issues or sensitivity.


To achieve the best results from your water flosser, Waterpik recommend that you floss daily for 1 minute. Both the Aquarius and the Ultra allow for 90 seconds of flossing at full pressure, providing you with enough water for a continuous flossing session — and more!

Interchangeable rotating tips

The Waterpik Aquarius and Ultra both feature a 360 degree rotating tip. While this may not seem like a big bonus, it has several great applications.

The 360-degree flossing tip rotation allows the tip to clean both the front and back of teeth without having to reposition the handle (view details). It makes water flossing simple, and for those For dexterity challenges this is vital.

Interchangeable tips are not essential but they do help to tailor your flossing experience to your unique needs. The Aquarius comes with one more tip than the Ultra does, but this is the toothbrush tip which is widely regarded to be the least useful!

The tips included with both are:

  • Classic Jet Tip (JT-100E) – The standard water flossing tip that comes with every Waterpik device.  And two members of your household can utilise the tips straight out of the box since two are included and color-coded.  
  • Plaque Seeker Tip (PS-100E) – Great for dental work like crowns, implants, and veneers.  This tip is clinically proven to remove up to 99.9% of plaque from treated areas in 3 seconds. It is also up to 2x as effective as string floss for improving gum health around implants.
  • Orthodontic Tip (OD-100E) – Composed of a tapered brush, this tip helps to remove hard-to-reach plaque around braces. It is also proven to be up to x3 as effective as string floss for removing plaque around braces.
  • Pik Pocket™ Tip (PP-100E) – For use on periodontal pockets and furcations.  This tip is composed of a soft rubber tip that is gentle and offers low-pressure delivery of water below the gum line for optimal rinsing.

Waterpik products have gained the trust of millions worldwide through consistently delivering quality products. Countertop water flossers typically have a longer life than cordless water flossers as they avoid problems with battery charge.

If you do encounter problems with your water flosser, the Aquarius and the Ultra both come with a 3 year warranty and spare parts for both are readily available.

Now that we have established the common ground, let’s take a look at:

4 Key Differences of the Aquarius and Ultra

Massage mode

Winner: Aquarius

The key feature that distinguishes the Aquarius from the Ultra is massage-mode (see more). Unlike the standard flossing mode, this delivers a series of pulses to the gum tissue and should be used at low pressure.

Massaging the gums is great for overall oral health but is particularly helpful for those with gum disease or gingivitis. The gentle massaging helps to promote blood flow to the area to assist with healing. It also helps to dislodge any food particles or plaque that can get stuck in periodontal pockets and furcations.


Winner: Aquarius

A timer is by no means a deal breaker but it is an incredibly useful tool. Many of us fail to brush our teeth for the correct time or fail to floss at all.

The built in timer on the Aquarius makes it so simple to floss for the recommended amount of time and the pacer notifies when you should switch to another part of your mouth.


Winner: Aquarius

As the new model, the Aquarius is undeniably more attractive than the Ultra. In general, it looks more modern, and it is also available in a wide range of colors, thanks to the Aquarius Designer range.

While the visual design has no impact on effectiveness, you need to invest in a water flosser that you will use. If a dated design means that you will hide your water flosser away instead of using it, spend the little extra and get an Aquarius Designer that you’ll be happy to show off.


Winner: Ultra

As the simpler model, the Ultra is cheaper than the Aquarius. If low cost is important to you, then rest assured that the Ultra is a great device in its own right.

That said, the Aquarius is the most well-known water flosser in the Waterpik range and, as a result, often has discounts applied to it – keep an eye out!

So what’s the bottom line?
