Let's take a look at the main features the Waterpik Ultra has to offer. Like other Waterpik brand water flossers, it has been proven in the lab to remove up to 99.9% of plaque with use of approximately 1 minute per day and is up to 50% more effective than standard floss when it comes to gum health improvement.

If water pressure is an important feature for you, you'll be happy to know that the Waterpik Ultra has 10 water pressure settings, between 10 to 90 PSI and 1400 pulses per minute. That wide range of pressure settings makes it ideal for those with sensitive gums to those who need that extra pressure to remove the plaque and debris from their gums and teeth.


A number of people are turned off or startled by the loud noise some water flossers make while in use. Waterpik has improved their design to address the noise issue; it is now smaller and quieter than previous models. Another advancement worth noting is the ergonomic handle with a pause button for added convenience.

Let's move on to the tips that are included with this model. In total there are 6 color-coded tips:

  • 2 Classic jet tips
  • 1 Pik Pocket tip
  • 1 Plaque Seeker tip
  • 1 Orthodontic tip
  • 1 Toothbrush tip

As for reservoir capacity, you are looking at 90+ seconds of usage that you can get out of the 650 mL tank. As it usually takes about a minute to complete the job, this is plenty of time and you shouldn't have to refill the tank until the next time you floss.

It is essential to weigh out the pros and cons of each model so that you can purchase a water flosser that is right for you.


  • More advanced model gives the user a quieter experience and a more ergonomic design.
