In order to adjust a degree of tight contact between a floor surface and a suction member of a vacuum cleaner, and to facilitate operation of the vacuum cleaner, an air flow adjusting valve is provided at a left end of an upper plate of the suction member. When a negative pressure in an inner chamber reaches to a certain valve, the air flow adjusting valve is opened and air is introduced through an air inlet. This facilitates movement of the suction member over the floor surface.
