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.

Disk broom, sweeping device and floor cleaning machine

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.

Floor cleaning machine

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.

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.
