The Oral-B iO 6 electric toothbrushes have 5 brushing modes. You can choose from a massage setting for your gums or an intense setting, for example. The iO 6 models have an interactive black and white display. On the display, you can see the brush setting and if you brush well, for example. You also get feedback on your brushing behavior in the app. The pressure sensor with light signal and the slowing down of the toothbrush prevents you brushing too hard.
