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.

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.

An apparatus for cleaning a floor includes a housing, wheels by which the apparatus is adapted to move; a motive device for moving the apparatus, a steering mechanism, and a cleaning assembly including a cleaning unit and an offset mechanism adapted to move the cleaning unit to or from an offset position projecting beyond one lateral side of the apparatus. In another embodiment, an apparatus for cleaning a floor includes a housing, wheels by which the apparatus is adapted to move, a motive device for moving the apparatus, a steering mechanism, and a cleaning assembly including a cleaning unit and a swing mechanism indirectly linking the cleaning unit to the steering mechanism such that when the apparatus is in an operative mode, the cleaning unit reorients its position in synchronization with the path of travel of the apparatus. Optionally, a lifting device may raise and lower the cleaning assembly.

An auxiliary waste removal system for a surface maintenance machine, having a vacuum wand for removing waste from the floor surface, a reusable bagless waste collection container removably coupled to the vacuum wand, and a vacuum source fluidly coupled to the bagless waste collection container, the vacuum source generating a vacuum flow from an inlet of the vacuum wand to a vacuum outlet, the vacuum outlet being positioned downstream of the bagless waste collection container and the vacuum source such that the waste suctioned from the floor surface by the vacuum wand travels along the vacuum flow path and is directly received in the bagless waste collection container.

Embodiments include a surface maintenance machine, comprising a maintenance tool chamber comprising a first side, a second side, a third side and a fourth side. A rotary broom is housed in the maintenance tool chamber and substantially enclosed by the first, second, third and fourth sides thereof. The rotary broom sweeps particulate from the surface. A vacuum system generates vacuum for drawing particulate swept by the rotary broom. The vacuum system is positioned proximal to the first side. A skirt assembly extends substantially around the second, third and fourth sides of the maintenance tool chamber. The skirt assembly has a vacuum passage defined therein and in fluid communication with the vacuum system to direct air flow into the vacuum passage, thereby drawing particulate into the vacuum passage and preventing particulate accumulation at portions of the second, third and fourth sides that are distal to the vacuum system.
