ABSTRACT:
The invention relates to a floor-care appliance with automatically adjusting vertical position of the brush-body rotary shaft. The shaft is placed in rotation via a drive belt from a motor, which shaft is borne by a rocker which is swingable as a function of the load on the brushes and is acted on in brush application position, and, in order to obtain a simplified construction with optimally constant work output, the rocker is swingable by the tension of the drive belt and has a deflection point which, from below, deflects the bottom-side pulling course of the drive belt.
