Claim:
1. A floor care appliance in the form of a brush vacuum cleaner having a brush set facing the floor for receiving a driven brush roller with an overload protection, comprising: a pivotable connecting element in the form of a connecting piece connecting the brush set to a filter housing which is attached to a handle in the form of a hand grip via corresponding connections; the brush set having at least one electric motor for a suction fan and for a drive of the brush roller, a torque detecting unit for detecting a torque of the brush roller; a switch arrangement configured to generate a safety shutdown above a predetermined torque threshold, due to overload, a driven element of the torque detecting unit being disposed in a drive train of the brush roller which, above the torque threshold, is configured to be coupled by means of a switchable coupling element to an associated body of rotation in the form of an eddy current disk made of electrically conductive material, the eddy current disk containing at least one magnet which is pivotably positioned on a fixedly mounted movable support, an adjustment of the support is made by a magnetic field of the coupled eddy current disk formed by the generated eddy current, and the support being configured to control the switch arrangement as the safety shutdown.
