A robot cleaner comprising: a cleaner body including a wheel unit and a controller controlling driving of the wheel unit a suction unit disposed in 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 the sensing unit includes a first sensing part disposed respectively inclined with respect to side and top surfaces at an upper corner portion of the cleaner body to simultaneously photograph front and upper parts of the cleaner body.

A robot cleaner comprising: a cleaner body including a dust container accommodation part formed to be recessed toward the front from the rear thereof; a suction unit mounted in the cleaner body to suck air containing dust; a dust container accommodated in the dust container accommodation part, the dust container collecting dust filtered from sucked air; and an exhaust port formed at an end portion of one rear side of the cleaner body, which surrounds the dust container accommodation part, to discharge filtered air to the outside, the exhaust port disposed along the height direction of the cleaner body.

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; a suction unit mounted in the cleaner body to suck air containing dust; a dust container detachably coupled to the dust container accommodation part, the dust container filtering and collecting dust from sucked air; and a dust container cover including a hinge part rotatably coupled to the cleaner body, the dust container cover detachably coupled to the dust container to cover a top surface of the dust container.

A autonomous cleaner includes: a cleaner body including a wheel unit for autonomous traveling; a suction unit provided to protrude from one side of the cleaner body, the suction unit sucking air containing dust; a sensing unit provided at the 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 hinge-coupled to the cleaner body to be rotatable, the dust container cover being provided to cover a top surface of the dust container when the dust container cover is coupled to the dust container.

A robot cleaner includes a main body, a moving unit for moving the main body, a cleaning module capable of being brought into contact with a floor surface at at least part of a lower surface thereof, and a module drive unit for controlling an angle of inclination of the lower surface of the cleaning module with respect to the floor surface.

A surface cleanup machine that can clean up grout off a surface or a floor is described.

The present disclosure relates to a plurality of autonomous mobile robots. A plurality of autonomous mobile robots comprise a first mobile robot including an antenna configured to transmit and receive signals, and a second mobile robot including a first antenna and a second antenna disposed on a front area of a main body thereof to transmit and receive signals to and from the antenna of the first mobile robot. The second mobile robot comprises a control unit configured to determine a relative position of the first mobile robot using the signal received by the first antenna and the second antenna.

An autonomous floor cleaner includes a base that is movable over a surface to be cleaned, a collection chamber associated with the base, and a rotating top mounted coupled with the base for rotation relative to the base, where the top carries at least one sweeping element for sweeping dirt on the surface to be cleaned toward the collection chamber.

A dirt removing device including: a cassette mechanism having a head formed with a beating face, a liquid accommodating portion for accommodating liquid, and a water supplying passage which is started from the liquid accommodating portion and penetrates into the entire head; and a device body having a vibration unit. The cassette mechanism is detachably received in the vibration unit, and the vibration unit, when being powered, causes the cassette mechanism to vibrate in a direction substantially orthogonal with the beating face of the head. The liquid is supplied from the liquid accommodating portion to the beating face of the head through the water supplying passage, along with the vibration of the cassette mechanism caused by the vibration unit.

The present invention relates to a floor surfacing machine (1) comprising a frame (2) that is carried by a first wheel (3) and a second wheel (4). The floor surfacing machine (1) further comprises a first motor (6), a handle arrangement (7), at least one planetary head (15) that is rotatably mounted to the frame (2) and at least one satellite surfacing head (19, 20, 21) that is rotatably mounted to the planetary head (15), where the first motor (6) is arranged to propel the planetary head (15). The floor surfacing machine (1) comprises a first control unit (10), and a remote control panel (11) which in turn comprises a second control unit (12) that is arranged to communicate with the first control unit (10). The floor surfacing machine (1) also comprises a second motor (22) that is arranged to propel the satellite surfacing heads (19, 20, 21) such that the planetary head (15) and the satellite surfacing heads (19, 20, 21) are independently operable.
