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. When the filter access door is open, the lift arm assumes the extended position to receive the filter unit in the filter seat. Moving the filter access door from the open position into the closed position when the filter unit is disposed in the filter seat causes the lift arm to move to the retracted position.

Abstract: A wheel for an autonomous cleaning robot that maneuvers the robot on a floor surface includes a tire having first and second opposing outer edges and a middle portion having a tread pattern between the first and second outer edges, the tread pattern comprising a plurality of raised tread having trenches therebetween. Each of the plurality of raised tread includes a first raised tread portion extending from the first outer edge to the middle portion and substantially perpendicular to the first and second outer edges; a second raised tread portion extending at an angle away from the first raised tread portion; and a third raised tread portion extending from the second raised tread portion to the second outer edge and substantially perpendicular to the first and second outer edges, the third raised tread portion being laterally offset from the first raised tread portion.
