A vacuum cleaner includes a suction nozzle including a housing that defines an inlet, a first shaft disposed at a side of the housing, a driver configured to rotate the first shaft, a rotating brush that extends along an axis and is configured to, based on rotation of the first shaft, rotate about the axis to thereby move dust on a surface to toward the inlet, a detachable cover configured to rotatably support a first end of the rotating brush, and a second shaft disposed at a second end of the rotating brush and configured to engage with the first shaft to rotate the rotating brush. The first shaft and the second shaft are configured to contact each other and to define first contact surfaces that have a spiral shape about the axis and that are configured to transfer rotational force from the first shaft to the second shaft.

Provided is a robot cleaner including a main body including a suction portion disposed thereon, main wheels for moving the main body, a side brush assembly disposed on the main body and rotating with a rotation shaft perpendicular to a rotation shaft of the main wheels, wherein the side brush assembly includes a housing for forming an exterior of the side brush assembly, a first force transmitter disposed in the housing and rotating by receiving a driving force, a second force transmitter in contact with the first force transmitter to rotate together when the first force transmitter is rotated, and a side brush coupled to the second force transmitter to rotate at the same rotation angle as the second force transmitter.

A rotary brush is easily attachable to and detachable from a body with less separation from the body during cleaning. A rotary brush attachable to a driving shaft rotatable about a rotation axis and including a protrusion includes a brush, a base to which the brush is attached, and a locking member that comes in contact with the base and the driving shaft to lock the base to the driving shaft.

A vacuum cleaner of the present disclosure includes a cleaner body having a suction motor provided inside thereof and a handle provided outside thereof, and a suction nozzle connected to the cleaner body, wherein the suction nozzle includes a housing having at least part of a front portion opened, and a rotary cleaning unit disposed inside the housing, having at least part thereof exposed through the opening of the housing, and configured to clean a floor by a rotating operation, wherein the rotary cleaning unit includes a cylindrical nozzle body rotatably installed inside the housing, and fiber filaments and metal filaments disposed on an outer circumferential surface of the nozzle body.

A side brush for a robotic cleaner. The side brush is rotatable about a rotation axis in a rotational direction and has a brush body and numerous linear bristles including a first bristle having a base end at the brush body and an opposite distal end. An imaginary line extends perpendicularly to the rotation axis. The first bristle extends in a bristle direction outwardly from the brush body. Seen in a top view, the bristle direction extends at a first angle to the imaginary line with the distal end pointing rearwardly in relation to the rotational direction. Seen in a side view, the bristle direction extends at a second acute angle to the rotation axis pointing away from the brush body. A robotic cleaner having such a side brush is also disclosed herein.

A vacuum cleaner of the present disclosure includes a cleaner body having a suction motor provided inside thereof and a handle provided outside thereof, and a suction nozzle connected to the cleaner body, wherein the suction nozzle includes a housing having at least part of a front portion opened, and a rotary cleaning unit disposed inside the housing, having at least part thereof exposed through the opening of the housing, and configured to clean a floor by a rotating operation, wherein the rotary cleaning unit includes a cylindrical nozzle body rotatably installed inside the housing, and fiber filaments and metal filaments disposed on an outer circumferential surface of the nozzle body.

A cleaner includes a case having an opening formed in a lower side. The cleaner also includes a brush assembly disposed inside the case. The brush assembly includes a horizontally disposed brush bar and a brush coupled to the brush bar. The cleaner includes a suction port for suctioning dust collected by the brush assembly. The cleaner also includes a motor that provides power to the brush assembly. Further, the cleaner includes an operation assembly, connecting the motor and the brush assembly, and converting a rotational movement of the motor into a translational motion of the brush assembly. The operation assembly includes a rotating member coupled to a shaft of the motor, a link connected to the rotating member, a connecting member connecting the brush bar and the link, and a guide rail for guiding the connecting member in a longitudinal direction.
