Our main recommendation
Our pick for the best overall water flosser is the Waterpik Aquarius.
In the sections below we explain how we came to this decision and offer some alternative choices for specific situations.
Our in-house dentist Dr. Gemma Wheeler explains the evidence for using an electric flosser, and our buyer’s guide includes further advice to help you decide.
It’s worth noting there are various other ways to refer to a water flosser, but they are one and the same: electric flosser, oral irrigator, water toothpick and water jet flosser are other common terms. Often they are referred to as a ‘Waterpik’ as this is the best-known brand in the market.
What to look for in a water flosser
In this post we offer recommendations for both corded (countertop) and cordless water flossers.
If you have space (approx 6 x 6 inches) for one in your bathroom, we recommend going for countertop over cordless
Both types of flosser come with similar features. Not all of them are necessary.
From our testing, the most essential features of a water flosser are:
45 seconds or more flossing time
Flossers with a water tank of around 200ml will achieve this. 45 seconds is enough time to get a thorough clean without having to refill. It can make the flosser slightly heavier but it is a worthwhile trade off.
2 or more pressure modes
If you have sensitive gums it is useful to be able to adjust the pressure.
Rotating nozzle (or handle if it’s a countertop flosser)
Having a 360 degree rotating nozzle makes it easier to reach all parts of the mouth.
Comfortable grip (cordless)
From our testing, a large area for the palm and fingers to grip onto is better than a slim handle. It’s also helpful if the grip is made from materials that prevent slippage, particularly when wet.
Water control button on the handle (countertop)
A button or switch on the flosser handle allows for much greater control of the water flow. This makes it easy to stop, start and pause the jet of water. No need to use the on/off switch on the countertop unit itself.
Hose storage (countertop)
Having a convenient place to tuck away the hose when not in use avoids trailing cables around the bathroom.

Best Countertop
Waterpik Aquarius WP-660
Why we chose it:
The Waterpik Aquarius has all of the essential features we look for in a water flosser.
It is fairly compact with hose storage to keep things neat, although there is no place to store any excess power cable.
In our testing, we found it easy to control the water flow from the handle, and the water pressure was easy to adjust with the rotating dial.
Twisting the top of the handle moves the nozzle and helps reach all areas of the mouth. A very thorough clean is achieved each time.
80 seconds is the minimum cleaning time available, even when set to the highest of the 10 pressure settings.

It has all the features we recommend and has been approved by the Oral Health Foundation and American Dental Association. This means that the flosser has been assessed by an independent panel of experts, and that it is safe and that it has the benefits it says it does.
