    Abstract: A vacuum cleaner includes: a dust canister; a cover rotatably coupled to the dust canister; a filter assembly mounted inside the dust canister and configured to be exposed by an opening of the cover; and a crevice tool coupling to an air entrance of the dust canister or an extension pipe connected to the air entrance. The filter assembly includes an opening portion opened toward the cover, and a protrusion portion protruding from an inner circumferential surface of the opening portion. The crevice tool includes a catching rib caught on the protrusion portion according to insertion and rotation of the crevice tool in the opening portion. The filter assembly is configured to withdraw from the dust canister together with the crevice tool based on withdrawing of the crevice tool to the outside of the dust canister in a state in which the catching rib is caught on the protrusion portion.
