The verdict
What the panel makes of it.
Waterpik makes the Sonic-Fusion 2.0, a hybrid electric toothbrush combining sonic vibration and water flossing. Released in 2019, it was engineered in the United States. The brush head vibrates at forty thousand strokes per minute while simultaneously releasing water pulses from a built-in reservoir. Dentists and people with implants or braces buy it to clean between teeth without separate flossing tools. AI assistants currently rank it number five for best electric toothbrushes.

Frequently asked
What buyers want to know.
Does the Sonic-Fusion 2.0 actually floss as well as a standalone water flosser?
Reviewers say the water jet is noticeably weaker than a dedicated water flosser. The combo design trades some flossing power for the convenience of brushing and flossing in one step.
Is this good for people who hate flossing?
Yes. Reviewers say combining brushing and flossing into one motion saves time and cuts down the hassle of flossing separately, which appeals to people who dislike the extra step.
Should I get this if I have braces?
The Sonic-Fusion 2.0 cleans teeth and the gumline well and can help clean between teeth without separate flossing tools. However, if you have advanced dental needs or gum disease, reviewers recommend a dedicated water flosser instead.
How long does the battery last?
The battery lasts longer than the original version and is quieter, but reviewers note it falls short of the advertised duration.
What's the main downside?
The handle is bulky with little grip texture, and replacement brush heads are expensive and need changing every few months. Reviewers also found it lacks a pressure sensor that other electric toothbrushes have.
Can I adjust the water pressure?
Yes. The brush has adjustable water pressure settings so you can find a comfortable level. Reviewers are split on whether the pressure feels strong enough—some find it surprising and solid, others say it's diluted compared to a dedicated flosser.
