         5 . The floor-cleaning machine according to  claim 1 , wherein a drive apparatus for moving the dirt-holding container between the dirt-holding position and the dirt-discharging position is associated with the retaining apparatus. 
     
     
         6 . The floor-cleaning machine according to  claim 5 , wherein the drive apparatus comprises an electric motor. 
     
     
         7 . The floor-cleaning machine according to  claim 5 , wherein the drive apparatus drives a pivoting movement of a link of the retaining apparatus. 
     
     
         8 . The floor-cleaning machine according to  claim 7 , wherein the drive apparatus comprises a chain, which transfers a torque of the drive apparatus to the link. 
     
     
         9 . The floor-cleaning machine according to  claim 1 , wherein the tipping drive comprises an electric motor. 
     
     
         10 . The floor-cleaning machine according to  claim 1 , wherein a tipping axis of the dirt-holding container is parallel to a pivot axis of the dirt-holding container for the movement by the retaining apparatus. 
     
     
         11 . The floor-cleaning machine according to  claim 1 , wherein the tipping drive acts effectively with torque on a tipping element of the dirt-holding container, which tipping element is connected to the tipping drive for conjoint rotation. 
     
     
         12 . The floor-cleaning machine according to  claim 1 , wherein in the dirt-holding position, the suction bar apparatus is covered at least in part by the dirt-holding container in relation to a height direction transverse to the chassis longitudinal axis. 
     
     
         13 . The floor-cleaning machine according to  claim 1 , wherein at least one of a space and a usable space is formed between a floor, on which the floor-cleaning machine is stood, the suction bar apparatus, and the dirt-holding container in its dirt-holding position. 
     
     
         14 . The floor-cleaning machine according to  claim 1 , wherein a brush apparatus having at least one brush is arranged on the chassis, by means of which brush apparatus dirt is feedable at least one of directly and indirectly to the dirt-holding container.
