A first motor and fan unit is mounted in the vacuum cleaner for producing suction in the suction nozzle and is operatively connected to the brush roller for rotating it. An upright housing is connected to the cleaning head, the housing having a handle for moving the vacuum cleaner along the floor during floor cleaning use. Contained in the housing are a dirt storage container, a passageway leading from the suction nozzle in the cleaning head to the storage container and a second motor and fan unit operatively associated with the storage container for drawing dirt laden air from the cleaning head through the passageway and into the storage container simultaneously with operation of the first motor and fan unit.
