         4 : The cleaning device of  claim 1 , wherein the sweeping and/or wiping movement at least partially comprises a pivoting movement of the at least one cleaning element, and
 wherein the at least one cleaning element has a pivot axle and the pivoting movement is realized around the pivot axle of the at least one cleaning element.   
     
     
         5 : The cleaning device of  claim 1 , wherein the actuating device forms a guided movement path for the at least one cleaning element for performing the cleaning movement. 
     
     
         6 : The cleaning device of  claim 1 , wherein the actuating device has at least one actuating-force-transmission element by which at least one actuating element is drivable, and
 wherein the at least one cleaning element, for performing the cleaning movement, is operatively connected to the at least one actuating element.   
     
     
         7 : The cleaning device of  claim 6 , wherein the at least one actuating-force-transmission element comprises an internally toothed gear and the at least one actuating element comprises an externally toothed gear. 
     
     
         8 : The cleaning device of  claim 7 , wherein the guided movement path is formed by the at least one actuating-force-transmission element, and
 wherein the at least one actuating element operatively connected to the cleaning element is guided along the movement path.   
     
     
         9 : The cleaning device of  claim 6 , wherein the at least one actuating-force-transmission element has a positionally fixed rotation axle, and
 wherein the movement path is provided radially around the positionally fixed rotation axle such that the at least one actuating element is guided along the movement path around the rotation axle of the actuating-force-transmission element.   
     
     
         10 : The cleaning device of  claim 4 , wherein the at least one actuating element and the at least one cleaning element are connected to one another by the pivot axle. 
     
     
         11 : The cleaning device of  claim 1 , further comprising:
 between the actuating device and the drive motor, drive-transmission device configure to transmit a drive force of the drive motor,   wherein the drive-transmission device has at least one drive-transmission means by which the at least one cleaning element undergoes acceleration during a performance of the sweeping and/or wiping movement.   
     
     
         12 : The cleaning device of  claim 11 , wherein the at least one drive-transmission means has a non-uniform transmission ratio. 
     
     
         13 : The cleaning device of  claim 12 , wherein the non-uniform transmission ratio is formed by at least one non-circular drive input element and/or at least one non-circular drive output element, so that, at least over a rotational-angle range of the at least one non-circular drive input element and/or at least one non-circular drive output element, a varying transmission ratio is formed. 
     
     
         14 : The cleaning device of  claim 11 , wherein the drive-transmission device has multiple drive-transmission means, and
 wherein each drive-transmission means has a non-uniform transmission ratio.   
     
     
         15 : The cleaning device of  claim 14 , wherein the non-uniform transmission ratios of the respective drive-transmission means are phase-offset with respect to one another such that, during performance of the sweeping and/or wiping movement, the at least one cleaning element is actuatable in a phase-offset manner by way of a decreasing transmission ratio such that the at least one cleaning element undergoes further acceleration by each of the drive-transmission means. 
     
     
         16 : The cleaning device of  claim 1 , wherein the at least one cleaning element has a longitudinally extending main body with a cleaning section, and
 wherein at least the cleaning section comprises a cleaning brush, a cleaning broom, a cleaning wiper, or a cleaning lip, or wherein a cleaning brush, a cleaning broom, a cleaning wiper, or a cleaning lip is arrangeable on the cleaning section.   
     
     
         17 : A cleaning robot for performing a cleaning operation on a floor, comprising:
 a housing;   a drive unit for travel movement of the cleaning robot on the floor, the drive unit comprising multiple wheels which are arranged on a bottom side of the housing; and   a control unit by way of which the cleaning operation for cleaning the floor is controllable,   wherein the cleaning robot is assigned at least one cleaning device of  claim 1 , by way of which the cleaning movement for cleaning the floor is performable.   
     
     
         18 : The cleaning robot of  claim 17 , further comprising:
 a collecting container configured to pick up foreign matter, which, with a pick-up section, is assigned to the cleaning device,   wherein at least the pick-up section of the collecting container is lowerable onto the floor by an actuating mechanism and a lowering movement of the collecting container and the sweeping and/or wiping movement of the cleaning element are matched to one another.   
     
     
         19 : The cleaning device of  claim 8 , wherein the guided movement path is formed by the inner side of the internally toothed gear. 
     
     
         20 : The cleaning device of  claim 10 , wherein the pivot axle is arranged centrally with respect to the at least one actuating element.
