A cleaning device including a covering hood having a lower surface facing a surface to be cleaned and an inlet on an upper surface thereof, through which contaminants are sucked; an air knife provided on a circumference of the covering hood and having an outlet for spraying high pressure air to the surface to be cleaned; a sweeper installed inside the covering hood and rotated by a driving motor to guide foreign objects swept away from the surface to be cleaned and contaminants floated by the high pressure air injection of the air knife to the inlet; a rotary member including a shaft passing through a circumferential surface of the covering hood and the air knife, and a rotary knob coupled to one end of the shaft to rotate the air knife to adjust an air spray angle.

A cleaning roller is mountable to a cleaning robot. The cleaning roller includes a sheath comprising a shell, an outer diameter of the shell tapering from a first end portion of the sheath and a second end portion of the sheath toward a center of the roller. The cleaning roller further includes a core including a central portion interlocked with the sheath to rotationally couple the core to the sheath and inhibit relative translation of the sheath and the core along an axis of rotation. An inner surface of the sheath and an outer surface of the core define an air gap therebetween, the air gap extending from the central portion of the core longitudinally along the axis of rotation toward the first end portion or the second end portion.

A surface cleaning head includes dual rotating agitators (e.g., a leading roller and a brush roll) and a removable cover for covering a top of the agitators and allowing access to the agitators from a top of the surface cleaning head. The dual agitators may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The brush roll may be located in a brush roll chamber and at least partially in an opening to the suction conduit. The leading roller may be positioned adjacent to and in advance of the suction conduit opening such that the leading roller engages debris and moves the debris toward the brush roll and the opening. The leading roller may be removable from the housing and held in place by the removable cover. The cover may be coupled using isolated latching mechanisms.

A management device that controls an autonomous cleaner includes a processing circuitry that obtains an electronic floor plan of a predetermined space, the predetermined space being a cleaning range of the autonomous cleaner. The management device estimates a person-present position at which a person is present in the predetermined space, and divides the predetermined space into a plurality of cleaning target areas to be individually cleaned by the autonomous cleaner. The management device further identifies a cleaning target area including the person-present position where the person is estimated to be present, as a person-present cleaning target area. The management device further identifies a cleaning target area around the person-present cleaning target area as a surrounding cleaning target area. The management device determines, among the multiple cleaning target areas, cleaning target areas other than the person-present cleaning target area and the surrounding cleaning target area to be cleanable areas.

A jet cleaning structure of a cleaning robot mainly comprising at least one jet port and one roller brush, wherein the jet port is disposed at a perimeter of a suction port at the bottom of the cleaning robot and is provided for ejecting air towards the underside of the suction port; the roller brush includes a shaft and a plurality of hard brush rods, wherein two ends of the shaft are disposed in a roller groove at the bottom of the cleaning robot, the plurality of hard brush rods is arranged in a straight or helical manner in equal parts on the shaft, when the cleaning robot is moving, the cleaning robot drives the shaft to rotate with respect to the moving direction of the cleaning robot so that the cleaning robot can use the plurality of hard brush rods to push away the fluff of the carpet and use the jet port to eject air to blow away the dust and foreign substance accumulated at the bottom of the fluff, thereby allowing the suction port disposed at the bottom of the cleaning robot to suck in the dust and foreign substance accumulated at the bottom of the fluff to the dust box and to effectively clean the carpet.

The present invention discloses a reciprocating hair removal device for floor cleaning, comprising a roller brush, a first driving structure for rotating the a roller brush, a sliding rail parallel to the roller brush and a sliding block connected to the sliding rail; wherein the surface of the rolling brush is formed with two spiral grooves opposite to each other, the head ends of the two spiral grooves are connected, and the tail ends of them are connected to form a reciprocating spiral groove; wherein the sliding block is provided with a hair removal knife extending from one end to the reciprocating spiral groove; when the roller brush rotates, the hair removal knife reciprocates along the reciprocating spiral groove with respect to the roller brush. Therefore, the present invention can automatically remove foreign matter such as hair entangled on the roller brush during the brush cleaning operation.

A robot cleaner includes an environment information detecting unit configured to obtain environment information regarding at least a portion of a cleaning area, a first communication unit configured to transmit and receive data to and from a different device positioned within the cleaning area, and a control unit configured to generate a control command regarding the different device in order to adjust the obtained environment information.

A cleaner head for a vacuum cleaning appliance includes a main body, a front agitator and a rear agitator, each agitator being rotatable relative to the main body, a mechanism for rotating the front agitator and the rear agitator, and a surface agitating edge located between the front agitator and the rear agitator.

A mobile robot of the present disclosure emits a first patterned light downward and forward from a main body on a floor of an area to be cleaned and a second patterned light upward and forward from the main body, determines an obstacle based on an image of each emitted patterned light which is incident on the obstacle, and senses a tilt of the main body to compensate for the tilt. In this manner, an obstacle may be determined accurately, and after the tilt compensation, redetermination is made as to whether it is possible to pass through, so as to enable the mobile robot to pass through or bypass the obstacle. Accordingly, the mobile robot may reach a wider area to be cleaned, thereby extending the area that may be cleaned, and enabling fast determination and operation for effective traveling, such that the mobile robot may escape from an obstacle without being limited thereby.

An autonomous cleaner includes a side brush that is provided to a bottom face of a body and sweeps up dust on a floor surface and a napped cleaning fabric that is provided in a rotating region of the side brush and wipes off the dust attached to the side brush. The side brush includes a brush shaft disposed at a position that is a predetermined distance above the floor surface and a pair of bristle bundles having different lengths. A shorter bristle bundle in the pair has a length that is sufficient to bring at least a tip end portion of the shorter bristle bundle into contact with the napped cleaning fabric. In this way, the dust attached to the side brush is wiped off by the napped cleaning fabric, which prevents the dust from being swept outside the body due to a centrifugal force. In addition, by disposing the brush shaft at a predetermined distance from the floor surface, it is possible to suppress entanglement with a carpet and the like and avoid a collision with a step. As a result, it is possible to provide the autonomous cleaner having a longer life and requiring infrequent maintenance.
