A vacuum attachment is provided to improve an adsorption force by occasionally applying a vacuum force to the vacuum attachment through a discharging member for discharging air between the vacuum attachment and a fixed surface. A vacuum attachment comprises a suction plate(10), a pressing plate(20), a cover(30) and a discharging member. The suction plate has a circumference adhered to a fixed surface and a space(A) which is open at a center part. The pressing plate is coupled to an upper part of the suction plate and has a discharging hole(27) for discharging the air in the space. The cover is separately coupled to an upper side of the pressing plate. The discharging member is provided between the pressing plate and the cover to guide the air from the space to the outside.
