A filtering device for an evacuation station includes a filter bag configured to collect debris evacuated from a cleaning robot by an evacuation station. The filtering device includes an interface assembly configured to interface with the evacuation station. The interface assembly includes (i) a base attached to the filter bag along an opening of the filter bag, (ii) an access door configured to provide or limit access to a space within the filter bag depending on whether the access door is in an open position or a closed position, and (iii) one or more hinges connecting the base to the access door. The access door is rotatable around the one or more hinges from the closed position to the open position.

Filtering devices for evacuation stations

Debris container

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.

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.
