The iO4 coaches you to a perfect clean. This is real-time personalized coaching. Having 4 brush modes (Daily Clean, Whiten, Sensitive, and Super Sensitive) Oral-B is on your team for your everyday brushing task. A round head and gentle micro-vibrations, the magnetic interaction delivers smooth, harmonious motion through a synchronized cleaning action (micro-vibrations synced with oscillations). A built-in-2-minute timer ensures an even easier experience, helping you get an optimal clean on all your teeth. The Oral-B's quadrant timer breaks the two minutes up into four 30-second intervals to clean each quadrant of your mouth. Delivering the perfect pressure is done by having a pressure sensor. The pressure sensor indicates optimal cleaning pressure and warns of over pressure.
