Abstract

The present invention relates to a suction cleaner which comprises a suction cleaner body and a dust cylinder, wherein the dust cylinder is provided with an air inlet and an air outlet; the suction cleaner body is provided with a base and a top cover; the dust cylinder is positioned between the base and the top cover; the suction cleaner body is connected with a rotary arm which rotates between two working positions corresponding to the suction cleaner body. When the rotary arm rotates in the primary working position, the rotary arm turns over until tightly enclasps the dust cylinder. When the rotary arm rotates in the secondary working position, the rotary arm turns over until releases the dust cylinder. The dust cylinder can be firmly positioned between the base and the top through tightly enclasping the dust cylinder by the rotary arm. Thus, the present invention can prevent the dust cylinder from displacing or falling off, and guarantee accurate contraposition of the suction cleaner when used. Thereby, the dust suction effect of the suction cleaner can be guaranteed.
