The invention relates to a floor vacuum cleaner comprising a dust collector arrangement mounted on rollers and/or runners, a suction hose, a suction tube and a floor nozzle, wherein the floor nozzle is fluidically connected to the dust collector arrangement via the suction tube and the suction hose, also comprising a motorized fan unit for suctioning an air stream through the floor nozzle, wherein the motorized fan unit is arranged between the floor nozzle and the suction tube such that an air stream suctioned in through the floor nozzle flows through the motorized fan unit and into the suction tube.

A surface cleaning head for a surface cleaning apparatus includes a dirty air inlet, a dirty air outlet, and a dirty airflow path extending between the dirty air inlet and the dirty air outlet. The surface cleaning head also includes an automated valve assembly operable to open and place the dirty airflow path in fluid communication with ambient pressure. The automated valve assembly is adjustably opened based upon a suction level within the dirty airflow path. The automated valve assembly includes an adjustable valve, a sensor operable to measure the suction within the dirty airflow path, and a controller operable to control the adjustable valve based on the sensor measurement.

A surface cleaning head 100 for a surface cleaning apparatus includes a dirty air inlet 108, a dirty air outlet 112, and a dirty airflow path extending between the dirty air inlet 108 and the dirty air outlet 112. The surface cleaning head 100 also includes an automated valve assembly 116 operable to open and place the dirty airflow path in fluid communication with ambient pressure. The automated valve assembly 116 is adjustably opened based upon a suction level within the dirty airflow path.
