Abstract: A surface cleaning machine is provided, including a chassis, at least one sweeping roller which is held on the chassis via a swing arm device, an adjusting device for adjusting a position of the at least one sweeping roller relative to a floor/ground, a sensor device which determines one or more quantities characterizing the relative position of the at least one sweeping roller to the floor/ground, and a control device which controls the relative position of the at least one sweeping roller to the floor/ground, wherein the adjusting device acts on the swing arm device, wherein a position of the at least one sweeping roller relative to the floor/ground is adjusted via a pivotal position of or at the swing arm device, and wherein the sensor device is associated with the swing arm device and detects floor/ground contact of the at least one sweeping roller via the swing arm device.

Abstract: A sweeping vehicle is provided including a disc brush and a holding device for the disc brush, the holding device having a holding part and a holding arm pivotably connected to the holding part, the holding device held on the vehicle by the holding part, and the disc brush held on the holding arm. The vehicle includes an adjusting device having an adjustment member of variable length engaging the holding arm, the holding arm being pivotable relative to the holding part upon change in length of the adjustment member. The holding device includes a brush carrier pivotably mounted on the holding arm and a coupling device coupling the brush carrier to the adjusting device, the brush carrier being pivotable relative to the holding arm upon change in length of the adjustment member for pivoting the disc brush about a pivot axis aligned at a slant to the axis of rotation.
