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.

Air volume flow and pushing force control device

A vacuum cleaner comprising a housing containing a housing part for receiving components of electrical appliances, and a dust compartment which can be closed by a dust compartment cover that is mounted in such a way that it can pivot between a position wherein the dust compartment is closed and a position wherein the dust compartment is opened. Said cover is provided with a socket for the electrical supply of additional appliances, said socket being connected to an electrical line leading out of the housing part. The aim of the invention is to ensure the operating safety of the inventive vacuum cleaner over a very long period of time. To this end, the housing is provided with a compartment for automatically inserting a section of the electrical line during the pivoting of the dust compartment cover from the opening position to the closing position.
