Description

With the Oral-B iO 9N Black with Extra Brush Attachment, you can see exactly how well you’re brushing thanks to a detailed mouth map in the app. This electric toothbrush uses 3D tracking with AI, so you can check the front, top, and back of every tooth. You can choose from 7 brushing modes, like a sensitive mode, a massage mode, or a tongue cleaning mode. This way, there’s always a mode that fits your needs. The interactive display gives you helpful feedback, like which brushing mode you’re using and whether you’ve brushed well. The multicolor pressure sensor warns you with red, white, or green light if you’re brushing too hard, too softly, or just right. This helps you always brush with the right amount of pressure.

Good brush, battery broke too quickly

Very good cleaning results
After six months: Gives up after 10 seconds, suddenly from full battery to completely empty

Doesn't last long enough.

Ease of use
Polishing quality
Lifespan

Unfortunately just after the 2 year warranty it now only lasts 1 minute with a full battery. I see this in other reviews too, for such an expensive product you would expect a better lifespan

Cleans super

You brush much better
Clear app
More drooling

Great brushing, and the app lets you easily track where you're brushing. The dental hygienist noticed. It was strange, though, that it broke after two years. And my husband's broke two weeks later. It was as if it had a timer for when it would break.
