摘要： The invention relates to an air volume flow and pushing force control device for a vacuum cleaner that has at least a motor, a dust receptacle and a suction nozzle, comprising a controller for controlling the motor power, a first sensor for detecting the air volume flow, which in conjunction with the controller forms a first control loop in order to maintain the air volume flow at a prescribed air volume flow value on the basis of the signal of the first sensor. The control device further comprises a second sensor for detecting a pushing force that is required for pushing the suction nozzle, and in conjunction with the controller, forms a second control loop in order to maintain the pushing force below a prescribed value on the basis of the signal of the second sensor, and a control loop selection device that activates one of the two control loops as a function of the signals of the two sensors.
