A road sweeper is provided with a rotatingly drivable sweeping brush, a sweepings container, a suction blower in flow communication with the sweeping brush for taking in dust-containing air, and at least one filter for separating dust from the air drawn in, wherein the filter can be acted upon on the clean side with external air stored in a pressure container and subject to pressure, via at least one external air valve for cleaning. In order for the filter to be cleaned off with as small an amount of external air as possible, the pressure container can have a pressure container wall located opposite the clean side of the at least one filter, the at least one external air valve being arranged on the wall, wherein a section of a suction conduit extends between the pressure container wall and the clean side of the filter.

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.
