Method and system for determining compliance with a guided cleaning session

A method (400) for determining a user's compliance with a guided cleaning session during use of an oral cleaning device (10) includes the steps of: (i) providing (410) an oral cleaning device including a sensor (28), a guidance generator (46), and a controller (30); (ii) providing (420), by the guidance generator, a guided cleaning session to the user; (iii) generating (430), at a first location during the guided cleaning session, sensor data from the sensor indicating a position or motion of the oral cleaning device; (iv) comparing (440) the generated sensor data to expected sensor data for the first location; and (v) generating (450), based on the comparison, an estimate of the user's compliance with the guided cleaning session.
