Setup, Compatibility & Care
To begin, charge the unit fully until the light indicator signals a full battery. Align the chosen brush head with the handle and snap it into place. To maintain optimal hygiene, rinse the brush head thoroughly under water after every use and wipe the handle with a damp cloth. Store the handle in an upright, dry position. Note that the iO3 is exclusively compatible with Oral-B iO replacement brush heads; standard Oral-B brush heads will not fit this handle. Replace your brush head every three months, or sooner if the bristles appear frayed.
