A personal care device drive unit comprises a main body housing a motor and enabling releasable connection to any selected one of a set of different functional units. A controller of the personal care device drive unit generates an output signal associated with the selected one of the functional units connected to the main body in dependence on a sensed motor current and a sensed vibration occurring in the main body. The use of both vibration sensing and current sensing (which detects the electrical motor load resulting from driving the selected one of the functional units connected to the main body) enables multiple different functional units to be identified more reliably.

A shaving apparatus, shaving head and/or at least one cutting unit for shaving both short and long hairs. The shaving apparatus, shaving head and/or at least one cutting unit includes an external cutting member and an internal cutting member movably arranged with respect to the external cutting member. A driver may be provided for moving the internal cutting member. The external cutting member is provided with a shaving section having two mutually connected lateral borders forming hair entry apertures. The internal cutting member is provided with cutting elements having cutting edges for cooperation with cutting edges of the external cutting member. A number of the hair entry apertures are formed by two substantially flat lamellae of the external cutting member which have free ends positioned between the borders of the shaving section.
