The super toothbrush can do that for 320 euros

We've become lenient when it comes to claims that artificial intelligence (AI) is involved. And so with the new toothbrush iO10 from Oral-B in our test not much of the alleged AI can be seen. But she is always smart. And networked too. However, users still have to clean properly.

Connect the charging station to the socket and start cleaning straight away, of course this is also possible with the iO10. But that is not the sole meaning of the matter. If you want to use all the functions, you first have to connect the charging station in the form of a small ice hockey puck called iOsense to your home WiFi network, which can be done using a free smartphone app. All you have to do is select the correct network and enter the associated password.

The brush itself has two buttons to turn it on and select one of seven brushing modes. There is also a small color display that, depending on the situation, shows the charging status, the respective cleaning mode with different intensity or a smiley for proper cleaning. When the toothbrush is not in use, it stands on the iOsense and is held in place with a magnet. If the battery is completely discharged, it can be recharged here within three hours. That's lightning speed compared to other electric toothbrushes.

The low volume of the toothbrush is noticeable when brushing your teeth. Anyone who listens to music or the news appreciates that. Oral-B relies on quiet magnetic motor technology. In addition, all sorts of sensors ensure that cleaning is done correctly. On the one hand, the pressure control protects against an incorrect cleaning technique. Anyone who presses on too hard and runs the risk of damaging their gums is warned directly on the toothbrush with a red light ring that lights up. If the pressure is correct, the ring lights up green.

On top of that, the iO10 recognizes which part of the mouth is being cleaned. For this purpose, the bit is divided into six zones, which must be worked through one after the other. The zones are also displayed on the charging station via blue LED light strips. Only when a zone flashes white has it been sufficiently cleaned. This works well as long as the head is held reasonably straight. Apparently, the 3D tooth tracking works via tilt sensors. In the test, we always needed a good two and a half to three minutes to process all zones. A smiley then praises the correct technique on the small color display.

There is even more detailed information and instructions in the smartphone app, which connects to the toothbrush via Bluetooth. In addition to the statistics of when cleaning was done and for how long, you can also see which zone is neglected most often. A point system from 1 to 100 indicates how well the cleaning was done. Medals mark success for all those who are motivated by it.

Conclusion: The best feature of the iO10 is its low volume, which makes brushing your teeth much more pleasant. In addition, the toothbrush gives its users a lot of control options. So if you have the impression that you are too careless when cleaning, this is made clear once again - especially in the smartphone app. That is the first possible step towards improvement. Despite the numerous functions, the iO10 is a bit expensive at a price of 320 euros. Incidentally, this also applies to the brush heads, which are twice as expensive compared to other Oral-B brushes.

The iO10 comes with a travel case, which only has space for a brush head. However, the toothbrush is more for individualists anyway, because it doesn't support multiple profiles in connection with the app, which doesn't really make it suitable for families. Oral-B should definitely improve here, which would be possible with an app update.

Because at this price it is hardly conceivable that every family member would buy their own toothbrush. This is not even necessary because everyone can use their own brush attachment. But then the statistics in the app get mixed up. The toothbrush can also be charged in the supplied travel case. The battery lasted about ten days in the test.
