In accordance with the present disclosure, a personal care device has a personal care head, a force sensor structured and/or arranged for acquiring force sensor data indicative of a force value with which the personal care head is pushed against a treatment surface along at least a first force direction, a processor structured and/or arranged for determining the force value from the force sensor data, a drive unit structured and/or arranged for driving the personal care head into a motion that is characterized by at least one motion parameter being one from the list comprising a speed, an amplitude and a frequency, the motion preferably being an oscillatory rotational motion, and a control unit structured and/or arranged for controlling the motion parameter of the personal care head in dependence on the determined force value such that in a first force value range extending from a first lower force value to a first upper force value the motion parameter is gradually increased from a first motion parameter start value to a first motion parameter end value when the force value increases from the first lower force value to the first upper force value.
