Abstract

The invention relates to a mobile floor-cleaning machine having a rotationally drivable, disk-like cleaning tool which is detachably held on a tool holder, the tool holder being connected to a drive shaft in a rotationally fixed manner. In order to develop the floor-cleaning machine in such a way that the cleaning tool can be easily replaced, the invention proposes that said cleaning tool is adapted to be detachably latched to the tool holder and to be disconnected from the tool holder in the axial direction by means of an unlatching mechanism which is adapted to be operated by the user.
