An oral cleaning device (10) minimizes drivetrain interference of a sensor and includes: a body portion (12)； a brush head member (14) extending from the body portion, the head having a bristle face (18), where the bristle face is configured to move relative to the body portion； a clock (32)； a sensor (28) in communication with the clock and configured to sample sensor data at a sensor sampling frequency (42) which is based on input from the clock； and a drivetrain (22) in communication with the same clock as the sensor, the drivetrain configured to generate movement of the bristle face at a first drivetrain frequency (40) which is based on input from the clock, where the sampling frequency and the first drivetrain frequency are coordinated to minimize drivetrain interference of the sensor.
