Abstract

A vacuum cleaner is disclosed. A vacuum cleaner of the present invention includes a body and a suction nozzle. The suction nozzle includes a housing and a rotating brush. The rotating brush includes a first rotating brush, a second rotating brush, and a coupler. The coupler combines the first rotating brush and the second rotating brush such that the rotating axes of the first rotating brush and the second rotating brush are on the same line.

Description

technical field [0001] The present invention relates to a vacuum cleaner, and more specifically, to a vacuum cleaner that can also cleanly clean dust on a smooth floor surface with a rotary brush. Background technique [0002] Vacuum cleaners have different cleaning capabilities depending on the type of brushes attached to them. [0003] On uneven carpets, hard plastic carpet brushes are beneficial in terms of cleaning efficiency. [0004] On the other hand, on a smooth floor such as a floor or floor leather, a floor brush made of a soft fleece material is advantageous in terms of cleaning efficiency. [0005] If you use a velvet floor brush, scratches on the floor caused by the brush will be prevented. In addition, if the brush made of fleece is rotated at a high speed, the fine dust adhering to the ground can be floated and sucked and removed. [0006] In connection with this, Korean Laid-Open Patent Publication No. 2019-0080855 (hereinafter, "Prior Document 1") disclos...
