  • Debris bins and mobile cleaning robots including same
    Patent number: 11641990
    Abstract: A mobile cleaning robot includes a removable filter unit configured to receive a supply airflow generated by a blower and to filter debris from the supply airflow, a filter seat, a filter access opening, a filter access door, and a filter presence system. The filter access door is pivotable between a closed position, wherein the filter access door covers the filter access opening, and an open position, wherein the filter access door is displaced from the filter access opening to permit access to the filter seat. The filter presence system is configured to: permit the filter access door to move from the open position into the closed position when the filter unit is disposed in the filter seat; and prevent the filter access door from being moved into the closed position when the filter unit is not disposed in the filter seat. The filter presence system includes a lift arm movable between an extended position and a retracted position.
