Abstract: This document describes a mobile cleaning robot that includes a chassis that supports a drive system, a debris collection volume; and a cleaning head formed to complete a bottom of the robot. The cleaning head includes a frame for affixing the cleaning head to the chassis, a monolithic housing having an interior cavity, a suspension linkage movably suspending the monolithic housing from the frame, the suspension linkage being configured to lift the monolithic housing, a diaphragm formed of a flexible material and mated to the monolithic housing, a rigid duct mated the frame to form a pneumatic path between the monolithic housing and the rigid duct through the diaphragm, and cleaning extractors disposed in the interior cavity of the monolithic housing.

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.
