ABSTRACT:
A dust container of an upright type vacuum cleaner includes a circular cover having a suction port and an exhaust port, a guide member attached to a lower surface of the cover to guide an air flow, a filter attached to a lower surface of the guide member, and a cylindrical container body provided to the lower surface of the cover to receive the guide member and the filter. The guide member guides air induced into the dust container through a suction port to spirally rotate within the container body. A supporting member positioned within the container body supports the filter such that the filter supports the cover.
