  • the cleaning arm 10 or connecting arm 11 is automatically brought back into the starting position after passing over the elevation H, in particular without the direction of rotation R of the sweeping brush 8 being changed.
  • variants of the method are also possible in which, by changing the direction of rotation R of the sweeping brush 8, the cleaning arm 10 or connecting arm 11 moves from the starting position under the base body 9 and/or radially inwards by means of the joint 13 is bent or folded, in particular in such a way that the side or top 12A of the cleaning head 12 that was previously directed upwards or in the starting position is used to clean the cleaning surface F.
  • a change in the side of the cleaning head 12 to be used can be brought about by changing the direction of rotation R.
  • the cleaning arm 10 or connecting arm 11 Due to the joint 13, the risk of tilting or damage to the sweeping brush 8 is further reduced, since the cleaning arm 10 or connecting arm 11 is bent or bent radially inwards more quickly/uninhibitedly in the event of a collision with the elevation H.
  • the cleaning arm 10 or connecting arm 11 can be designed to be stiffer compared to the embodiments without the joint 13, whereby a higher cleaning performance is achieved.
  • the proposed solution therefore makes it possible for obstacles or elevations H to be driven over better by means of the cleaning device 1 despite high cleaning performance and reduced wear, with the risk of tilting and/or (unintentional) changes in the direction of travel being reduced.
  • the advantageous properties of flexible or flexible sweeping brushes 8 can be combined with stiffer sweeping brushes 8.
