A floor cleaning machine having a machine frame, having a chassis attached to the machine frame for moving the floor cleaning machine over a floor surface to be cleaned, having a cleaning head, which is mounted on the machine frame in a height-adjustable manner, such that the cleaning head can be lowered toward the floor surface and lifted away from it, having an adjusting element which is movably mounted on the machine frame between a first and a second end position and which is coupled to the cleaning head in such a way that on movement of the adjusting element to the first end position the cleaning head is lowered and is pressed toward the floor surface and that, on movement of the actuating element toward the second end position, the cleaning head is lifted from the floor surface, having an actuator which has a first and a second coupling end (59, 61), the actuator having a drive which is designed such that the spacing of the first and second coupling ends (59, 61) between a first actuator end position and a second actuator end position can be set, characterized in that the first coupling end of the actuator is coupled to the actuating element in such a way that on movement of the first coupling end toward the first actuator end position, the actuating element is subjected to a force which drives the actuating element toward the first end position, and wherein the second coupling end of the actuator is coupled to the actuating element in such a way that on movement of the second coupling end toward the second actuator end position, the actuating element is subjected to a force which drives the actuating element toward the second end position. having a machine frame, having a chassis attached to the machine frame for moving the floor cleaning machine over a floor surface to be cleaned, having a cleaning head, which is mounted on the machine frame in a height-adjustable manner, such that the cleaning head can be lowered toward the floor surface and lifted away from it, having an adjusting element which is movably mounted on the machine frame between a first and a second end position and which is coupled to the cleaning head in such a way that on movement of the adjusting element to the first end position the cleaning head is lowered and is pressed toward the floor surface and that, on movement of the actuating element toward the second end position, the cleaning head is lifted from the floor surface, having an actuator which has a first and a second coupling end (59, 61), the actuator having a drive which is designed such that the spacing of the first and second coupling ends (59, 61) between a first actuator end position and a second actuator end position can be set, characterized in that the first coupling end of the actuator is coupled to the actuating element in such a way that on movement of the first coupling end toward the first actuator end position, the actuating element is subjected to a force which drives the actuating element toward the first end position, and wherein the second coupling end of the actuator is coupled to the actuating element in such a way that on movement of the second coupling end toward the second actuator end position, the actuating element is subjected to a force which drives the actuating element toward the second end position.
