The drive system inside the new Oral-B iO electric toothbrush has been transformed, from a typical mechanical motor with gears, to a new frictionless magnetic drive.
This new linear magnetic drive distributes energy evenly to the tips of the bristles, without any energy loss or sound. This results in a smooth and super quiet experience.
