Abstract: A floor cleaning machine that includes a disc broom that is rotatable about a rotation axis. The disc broom has a base body, bristles and a cover element. The base body has a circumferential outer edge. The bristles are attached at one end to the base body and extend away from the base body towards a sweeping plane that is perpendicular to the rotation axis. The cover element has a shell that is made of a flexible material. The shell extends away from the base body and towards the sweeping plane. The shell has an inner side, which faces an interior of the shell, and an outer side that faces an exterior of the shell. The shell envelopes the bristles perpendicularly to the rotation axis such that the bristles are disposed in the interior of the shell. A related disc broom and sweeping device are also provided.

Abstract: A floor cleaning machine having a base, a suction foot, a dirty water tank in fluid communication with the suction foot, a suction turbine, and a separation container. The suction turbine is attached to the base and generates a suction air flow from the suction foot into the dirty water tank. The suction turbine has a housing with an inlet opening and an outlet opening through which air flows. The separation container adjoins the suction turbine housing and has an interior, which that communicates with the inlet opening and a bottom wall section that faces the interior. The bottom wall section is disposed vertically lower than the inlet opening. A drainage opening leads out of the bottom wall section into the environment and is provided with a valve that is closed during operation of the suction turbine is in operation and open when the suction turbine is not operated.

Abstract: A method for operating a floor cleaning machine having a selectively activatable cleaning element that is configured to engage with a floor cleaning surface when the cleaning element is activated. The method includes determining a transport path and an additional transport path; determining a work area and an additional work area, which are connected to the transport path and the additional transport path; and operating the floor cleaning machine over a route that includes a plurality of transport movements, which occur along the transport path and the additional transport path, and a plurality of cleaning movements that occur over the work area and the additional work area. The cleaning element is deactivated during transport movements and is activated during cleaning movements.

Abstract: A floor cleaning machine having a movable adjustment element, a suction foot, a cleaning head and a drive. The adjustment element is coupled to the cleaning head, the suction foot and the drive. The drive is configured to move the adjustment element between a first position, in which the cleaning head and suction foot are raised, a second position, in which the cleaning head is raised and the suction foot is lowered, and a third position in which the cleaning head and suction foot are lowered.

Abstract: A floor-cleaning robot having a chassis for moving the floor-cleaning robot in a direction of travel over a surface to be cleaned, a cleaning implement, a control unit and first and second measuring devices for three-dimensional distance measurement. Each of the first and second measuring devices is configured to sense distance between the measuring device and a plurality of surface elements within a respective solid angle that is spanned from the measuring device. The first and second measuring devices are aligned in such a manner that the direction of travel runs through the first solid angle. The second solid angle is offset in relation to the first solid angle. The control unit is designed to generate and/or update a representation of the surface to be cleaned, on the basis of the distances from surface elements sensed by first and second measuring devices.

Abstract: A suction foot for a floor cleaning machine having an outer body, which has side pieces having an L-shaped longitudinal cross-section comprising a first horizontal side piece and a second vertical side piece, which extends perpendicular to the first side piece, having an inner body, which is releasably attached to the outer body. The inner body is coupled to the outer body with a sliding movement that is perpendicular to the first horizontal side piece and parallel to the second vertical side piece. A tension band is provided to press a sealing strip against the inner body. The ends of the tension band engage with the ends of the inner body.

Abstract: A vacuum sweeping machine having a chassis, which is configured for moving the vacuum sweeping machine over a surface to be cleaned, a sweeping roller, a suction extraction device, a side broom and a connecting line. The sweeping roller, which is driven in rotation, is mounted on the chassis and surrounded by the sweeping-roller housing. The sweeping roller extends along its rotational axis between a first and a second side wall of the sweeping-roller housing. The suction extraction device has a suction side that is connected to the sweeping-roller housing for the purpose of suction extraction of dust-laden air. The side broom, which is driven in rotation and mounted on the chassis, is surrounded by an enclosure. The connecting line is provided between the sweeping-roller housing and the enclosure. Coupling of the connecting line to the sweeping-roller housing is provided in one of the side walls.
