Abstract

A vacuum cleaner is disclosed. A vacuum cleaner of the present invention includes a body and a suction nozzle. The suction nozzle comprises a body shell and a driving part. The driving part comprises a motor and a transmission device. The motor is located behind the rotating brush. The transmission transmits rotational motion of the motor to the rotating brush.

Description

technical field [0001] The present invention relates to a vacuum cleaner, and more specifically, to a vacuum cleaner capable of cleaning 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 attached to the ground can be floated, and then sucked in and removed. [0006] In connection with this, Korean Laid-Open Patent Publication No. 2019-0080855 (hereinafter, "Existing Document 1") dis...
