Abstract (en)
[origin: WO2020207603A1] The invention relates to a surface cleaning machine which comprises a cleaning head (12), at least one cleaning roller unit (16, 18) that is arranged so as to rotate on the cleaning head (12), and at least one drive motor (32, 34) for rotationally driving the at least one cleaning roller unit (16, 18), wherein a rotational speed of the at least one cleaning roller unit (16, 18) can be varied, and a rotational speed adjustment device (206) is provided for the at least one cleaning roller unit (16, 18), and a boost mode is provided in which a rotational speed of the at least one cleaning roller unit (16, 18) is increased with respect to a standard rotational speed of the at least one cleaning roller unit (16, 18), and/or a sweeping mode is provided in which the rotational speed of the at least one cleaning roller unit (16, 18) is reduced with respect to the standard rotational speed of the at least one cleaning roller unit (16, 18).
