1. A personal care device comprising:
a main body;
a main functional unit supported by the main body;
an ancillary functional unit supported by the main body and comprising a treatment head; and
a coupling structure that permanently connects the ancillary functional unit to the main body,
wherein the coupling structure:
is configured to allow displacement of the ancillary functional unit relative to the main body from a non-operational position to an operational position; and
comprises a biasing arrangement configured to exert a biasing force on the ancillary functional unit to displace the ancillary functional unit from the non-operational position towards the operational position and to hold the ancillary functional unit in the operational position,
comprises a magnet arrangement configured to exert, in addition to the biasing force of the biasing arrangement, a magnetic holding force on the ancillary functional unit in the operational position of the ancillary functional unit, for retaining the ancillary functional unit in the operational position.
