A brush type vacuum cleaner having a filter housing and a suction, or brush-suction, head. The filter housing is pivotally connected to the brush-suction head by a rigid guide element or rigid connector that includes two air channels for channelling air between the filter housing and the brush-suction head. The air channels include openings for connection to the suction blower of the vacuum cleaner and the vacuum mouthpiece of the brush-suction head.
