VACUUM CLEANER

PURPOSE: A vacuum cleaner is provided to maximize the capacity of dust stored inside of a dust collecting vessel. CONSTITUTION: Dust storages(214,216) are formed in a dust collecting vessel(210). A pressurizing member(270) is rotatably installed inside of the dust collecting vessel. Multiple contact parts are formed in the dust collecting vessel, and contacted with the pressurizing member when the pressurizing member is rotated. A rotation shaft(274) provides the rotation center of the pressurizing member, and is crossed with the inner surface of the dust collecting vessel. The curvature of an external wall of the dust collecting vessel which forms a first space, and the curvature of the external wall of the dust collecting vessel which forms a second space are different each other.
