A vacuum cleaner having a hollow housing in which air flows from the suction inlet adjacent to a brush-type agitator that contacts the surface to be cleaned to an outlet in the housing. The air path passes through a dust collecting bag and thereafter cools a motor-fan unit and finally exits through the outlet in the housing. The structure includes a biasing assembly for the agitator which is yieldable; and is further provided with an adjustment that selectively changes the vertical distance between the brush and the surface to be cleaned. The structural arrangement further comprises a parking device which lifts the rotary agitator from contact with the floor when the vacuum cleaner is not being used, and an adjustment means for resetting the position of the rotary agitator when the brushes are worn. |
