All Waterpik® water flosser models deliver clinically proven benefits. But which model is best for you, and how do you choose between countertop models and cordless styles?

Choosing the best Waterpik® water flosser depends on your needs and priorities.

To help you decide, let’s take a closer look at 3 key features:

  1. Water pressure
  2. Reservoir capacity
  3. Size and portability

#1 Water Pressure

Water pressure settings let you control the force of the water spray produced by the water flosser. Our countertop models offer a much greater range of water pressure — from extra gentle to maximum cleaning.

Experienced Waterpik® water flosser users tend to like the higher pressure settings. If you have sensitive areas, you may also prefer the lower pressure settings offered by a countertop model.


#2 Reservoir Capacity

Countertop water flossers hold more water than cordless models:

Depending on the pressure setting in use, you can floss for 60–90 seconds with a countertop model, compared to 30–45 seconds for a cordless model.

This means that you may need to refill a cordless model in order to complete water flossing.


#3 Size and Portability

The trade offs of a lower pressure range and smaller reservoir of a cordless water flosser may be the right choice if size and portability are more important to you.

For example, a cordless water flosser is helpful for:

  • Bathrooms with a small countertop or limited storage space
  • Travel (especially AA-battery operated and global voltage cordless models)
  • Use in the shower (waterproof cordless models)
  • As an alternative to your countertop model when you are away from home
