    Abstract: A mobile robot system includes a docking station and a mobile robot. The docking station includes a platform, first and second charging contacts on the platform, and first and second ramp features on the platform. The robot includes a housing, first and second drive wheels, first and second raised charging contacts on a bottom of the housing, and a cleaning module including at least one rotatable cleaning head that extends below the bottom of the housing. The robot is movable from an approach position with the robot spaced apart from a front of the platform to a docked position with the robot on the platform and the docking station charging contacts engaged with the robot charging contacts. As the robot moves from the approach position to the docked position, the robot engages the first and second ramp features and the cleaning mechanism is lifted over the docking station charging contacts.

    Abstract: An evacuation station for collecting debris from a cleaning robot includes a controller configured to execute instructions to perform one or more operations. The one or more operations includes initiating an evacuation operation such that an air mover draws air containing debris from the cleaning robot, through an intake of the evacuation station, and through a canister of the evacuation station and such that a receptacle received by the evacuation station receives at least a portion of the debris drawn from the cleaning robot. The one or more operations includes ceasing the evacuation operation in response to a pressure value being within a range. The pressure value is determined based at least in part on data indicative of an air pressure, and the range is set based at least in part on a number of evacuation operations initiated before the evacuation operation.

    Abstract: A bag-based filtering device for collecting debris from a cleaning robot via a debris evacuation station includes a filter bag configured to separate at least the portion of the evacuated debris from a flow of air generated by the evacuation station. The filtering device includes a conduit extending inward from an opening of the filter bag into the receptacle. The conduit is configured to pneumatically connect a receptacle of the filtering device with an inlet of the filtering device to direct the flow of air generated by the evacuation station through the filter bag to separate at least the portion of the evacuated debris from the flow of air.
