A cleaner includes a cleaner main body, and a suction unit connected to the cleaner main body to suck air containing dust, and provided with a brush assembly brought into contact with a floor, wherein the brush assembly includes a rotating rod rotatable in one direction, a brush portion protruding from an outer circumferential surface of the rotating rod to rotate together with the rotating rod, and a blade erected at the rear of the brush portion in the one direction to be adjacent to the brush portion, and brought into contact with the brush portion during the rotation in the one direction, to prevent foreign substances from getting tangled in the brush portion. This configuration may prevent foreign substances such as hair and the like from being tangled in the brush portion during an operation of the cleaner.

Cleaner

A robot cleaner comprising: a cleaner body including a controller, the cleaner body having a dust container accommodation part formed therein; a wheel unit mounted in the cleaner body, the wheel unit of which driving is controlled by the controller; and a dust container detachably coupled to the dust container accommodation part, wherein a first opening and a second opening are disposed at the same height in an inner wall of the dust container accommodation part, wherein the dust container includes: an entrance and an exit, disposed side by side along the circumference of the dust container, the entrance and the exit, respectively communicating with the first opening and the second opening when the dust container is accommodated in the dust container accommodation part; and a flow separating part extending downwardly inclined along the inner circumference of the dust container.

Autonomous cleaner

A robot cleaner comprising: a cleaner body including a controller, the cleaner body having a dust container accommodation part formed therein; a wheel unit mounted in the cleaner body, the wheel unit of which driving is controlled by the controller; and a dust container detachably coupled to the dust container accommodation part, wherein a first opening and a second opening are disposed at the same height in an inner wall of the dust container accommodation part, wherein the dust container includes: an entrance and an exit, disposed side by side along the circumference of the dust container, the entrance and the exit, respectively communicating with the first opening and the second opening when the dust container is accommodated in the dust container accommodation part; and a flow separating part extending downwardly inclined along the inner circumference of the dust container, the flow separating part separating the flow of air introduced into the entrance from the flow of air discharged toward the exit to be respectively guided to lower and upper portions thereof.

An agitator and a robot cleaner including an agitator. The agitator includes a body configured to be rotated, a plurality of couplers formed at the body and arranged to be spaced apart from each other by a predetermined distance, and a first member and a second member coupled to any one of the couplers and configured to contact a surface to be cleaned during rotation of the body. The first member and the second member extend different lengths from the body in a radial direction.

Agitator and robot cleaner including the same

A robot cleaner (or autonomous cleaner) charging system includes a first light emitting device to output an optical signal for inducing a docking of the robot cleaner, a second light emitting device and a third light emitting device to output an optical signal for inducing a homing of the robot cleaner, and provided at left and right of the first light emitting device, respectively, and a light emitting device fixing member to set position and direction of the first, second and third light emitting devices.

Robot cleaner system having charging station

A robot cleaner comprises: a cleaner body including a controller, and driving wheels having their driving controlled by the controller; a bumper mounted to a bumper mounting portion formed on a front surface of the cleaner body, and configured to be inward moveable by an external force; and a cliff sensor mounted in an opening downward open at a bottom part of the cleaner body, and configured to sense a lower side terrain, wherein the bumper is provided to cover the cliff sensor in a state that the bumper has been inward moved by an external force.

Robot cleaner

A robot cleaner comprising: a cleaner body including a wheel unit for autonomous traveling and a suction unit sucking air containing dust; a sensing unit disposed at one side of the cleaner body; a dust container accommodated in a dust container accommodation part formed at the other side of the cleaner body, the dust container collecting dust filtered from sucked air; and a dust container cover disposed to cover a top surface of the dust container, wherein an upper end of the sensing unit is formed at a position protruding upward from a top surface of the cleaner body and a top surface of the dust container cover.

A robot cleaner comprising: a cleaner body including a wheel unit and a controller controlling driving of the wheel unit; a suction unit disposed to protrude from the cleaner body, the suction unit sucking air containing dust; and a sensing unit disposed at the front of the cleaner body in which the suction unit is disposed, wherein at least one portion of the sensing unit is disposed to overlap with the suction unit in the top-bottom direction of the cleaner body.

A robot cleaner comprising: a first housing including a controller and a driving wheel of which driving is controlled by the controller; a second housing provided at one side of the first housing, the second housing having a brush module or mop module mounted thereto; a front bumper provided at a front portion of the second housing, the front bumper configured to be movable to the inside of the second housing when the front bumper is in contact with an obstacle; at least one sensing means provided at the inside of the front bumper to sense a movement of the front bumper to the inside of the second housing; side bumpers respectively provided at left and right side portions of the second housing, the side bumpers each being configured to movable to the inside of the second housing when the side bumper is in contact with an obstacle; and a link member provided at the inside of the side bumper to allow the side bumper and the front bumper to interlock with each other such that, when the side bumper is moved to the inside of the second housing, at least one portion of the front bumper is moved together with the side bumper to the inside of the second housing.
