The present disclosure provides a Foreign Object Debris (FOD) Collection Device that comprises a carriage, a hitch, a holding chamber, a powered sweeper, and a funneling component. The carriage moves along a surface. The hitch couples the carriage to an Automated Mobile Robot (AMR) such that the automated robot drives movement of the carriage along the surface. The holding chamber is supported on the carriage and comprises an opening through which debris are passable into the holding chamber. The powered sweeper comprises a movable brush supported on the carriage and is operatively connected to a power supply of the Automated Mobile Robot. The funneling component is located between the movable brush and the holding chamber and is moved by the powered sweeper along surface S such that the debris swept by the movable brush are guided by the funneling component into the opening of the holding chamber.

An autonomous coverage robot includes a cleaning assembly having forward roller and rearward rollers counter-rotating with respect to each other. The rollers are arranged to substantially maintain a cross sectional area between the two rollers yet permitting collapsing therebetween as large debris is passed. Each roller includes a resilient elastomer outer tube and a partially air-occupied inner resilient core configured to bias the outer tube to rebound. The core includes a hub and resilient spokes extending between the inner surface of the outer tube and the hub. The spokes suspend the outer tube to float about the hub and transfer torque from the hub to the outer tube while allowing the outer tube to momentarily deform or move offset from the hub during impact with debris larger than the cross sectional area between the two rollers.

A vacuum cleaning utensil has a brush arranged for rotating about a substantially vertical axis. Further, the vacuum cleaning utensil has a guide for pushing the brush towards a surface to be cleaned during only a part of the rotation of the brush. During another part of the rotation, the brush is released from the surface to be cleaned.

Disclosed is a cleaner capable of autonomously traveling while performing a mopping task, the cleaner including: a body which defines an exterior appearance of the cleaner; at least one mop module which has at least one mop provided in contact with a floor, and which supports the body against the floor; and a tilt information acquisition unit configured to acquire tilt information of the body in relation to the floor. At least one specific part may comprise the at least one mop, may be a whole or part of the at least one mop module, and may be defined such that the at least one specific part is provided detachable from other parts of the cleaner except for the at least one specific part and that the body tilts in relation to the floor due to gravity while the at least one specific part is separated from the other parts. The cleaner may further comprises a controller which is configured to: based on at least the tilt information, determine satisfaction or unsatisfaction of a predetermined separated condition that is preset to be satisfied when the specific part is separated from the other parts; and, when the detachments condition is satisfied, control a predetermined mop separation error response operation.

A method of controlling a moving robot is provided. The method of controlling a moving robot includes the steps of: (a) performing a basic motion of the moving robot which moves on a rotating mop; (b) measuring the slip rate of the moving robot; and (c) controlling the travel of the moving robot.

A turntable structure includes a cleaning turntable having one side connected with a cleaning piece; an adjusting component slidably connected with the cleaning turntable along a target direction, and located on another side of the cleaning turntable opposite to the cleaning piece, the adjusting component having a side far away from the cleaning turntable and connected with a driving mechanism of a robot to rotate the cleaning turntable, the target direction being parallel to a rotating shaft of the cleaning turntable; a pressure unit provided between the cleaning turntable and the adjusting component and for pressing against the cleaning turntable; and a first limiting structure configured to limit a sliding distance of the cleaning turntable relative to the adjusting component along the target direction.

A cleaning pad for an autonomous cleaning robot evenly wets and collects debris for cleaning operations. The pad includes a core of absorbent layers for absorbing liquid through capillary action and for distributing the liquid within the cleaning pad. The pad includes a wrap layer around the core, the wrap layer comprising a fibrous layer that is flexible and absorbent, the fibrous layer configured to absorb liquid through capillary action and transfer the liquid to the core. The pad includes one or more transition regions spanning a cleaning width of the cleaning pad, the one or more transition regions dividing the cleaning pad into at least two segments. The forward positioned segment of the pad, of the at least two segments of the pad, has a lesser thickness compared to a thickness of an aft positioned segment of the at least two segments.

The present application provides a debris bin assembly including: a debris bin housing and a debris discharge valve; the debris bin housing includes an inner cavity, and an air inlet, a debris outlet, and at least one air guide portion that are disposed in communication with the inner cavity, and the air inlet is in communication with a debris inlet channel of the cleaning robot; the debris discharge valve is disposed at the debris outlet and configured to open the debris outlet to evacuate debris from the inner cavity in response to a vacuum negative pressure, and to close the debris outlet after the vacuum negative pressure is withdrawn; the at least one air guide portion is configured for being in communication with an external air and configured to guide a debris discharging airflow into the inner cavity in response to the vacuum negative pressure in the debris outlet.

The disclosure provides a debris bin assembly, a cleaning robot and a cleaning robot system, the debris bin assembly includes a debris bin housing, a filter assembly, and a flow guide plate, the debris bin housing includes a top portion and a bottom portion disposed opposite to the top portion, and a side housing surrounding the top portion and the bottom portion, the top portion, the bottom portion and the side housing are enclosed to form an inner cavity, the top portion of the debris bin housing is provided with an air exhaust channel communicating with the inner cavity and an air outlet communicating with the air exhaust channel, the side housing is provided with an air inlet communicating with the inner cavity, the air inlet inclines towards a side where the top portion is located, the filter assembly is disposed in the air exhaust channel of the top portion, the flow guide plate is located in the inner cavity and is disposed opposite to the air inlet, the flow guide plate extends from the top portion to the bottom portion and is configured for intercepting, decelerating and laterally guiding air flow entering from the air inlet, so as to decelerate and laterally guide air flow carrying debris, which avoids debris directly impacting a filter screen at a high speed and attaching to it, and consequently, a problem that the filter screen is easily blocked is solved.

A mobile cleaning robot can include a body, a drive wheel, and a plurality of skids. The drive wheel can be connected to the body and can be engageable with a floor surface of an environment. The drive wheel can be operable to move the mobile cleaning robot about an environment. The skids can be separate skids that can be connected to the body and can be engageable with the floor surface to support, together with the drive wheel, the mobile cleaning robot with respect to the floor surface.
