Waterpik Aquarius WP-660 vs Ultra WP-100: Key Differences

Main difference:  When comparing the Aquarius and the Ultra the main difference is the design. The Ultra has an outdated, large design that takes up a lot of space on your bathroom table.

With better on/off functions and smaller compact features, the Aquarius looks better is quieter and has a modern LED function indicator.

What we don’t like:

  1. Timer does not automaticaly turn itself off. Just a reminder. 
  2. Not much storage space for your tips. 

How the Waterpik Ultra WP-100 Shines:

  1. Has more storage areas for tips. 4 instead of the Aquarius 2.
  2. Ultra is cheaper. $59.99 compared to $79.99.

What we don’t like:

  1. Old, outdated design
  2. Waterpik unlikely to continue this model in the future.

Why Water Flossers Are Great For Oral Care

Oral hygiene is something no one should neglect as it can not only lead to dental problems, but it can also have a negative impact on your overall health.

The good news is you can take better care of your teeth yourself with the various products out there. If you want to reduce plaque, gingivitis and gum disease then water flossers are pretty much the standard items on the market these days.

If you have braces, implants, crowns, bridges or veneers, then again there is no going wrong with a decent water flosser.

Water flossers use a pulsating jet of water that pressure sprays between your teeth and below the gum line to remove plaque and food debris.

There is no longer a reason to use traditional string floss when you have the safer option of using a water flosser. Here’s our top 2 countertop water flossers reviewed.
