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 mobile robot configured to travel across a residential floor or other surface while cleaning the surface with a cleaning pad and cleaning solvent is disclosed. The robot includes a controller for managing the movement of the robot as well as the treatment of the surface with a cleaning solvent. The movement of the robot can be characterized by a class of trajectories that achieve effective cleaning. The trajectories include sequences of steps that are repeated, the sequences including forward and backward motion and optional left and right motion along arcuate paths.

Abstract: A piezoelectric debris sensor and associated signal processor responsive to debris strikes enable an autonomous or non-autonomous cleaning device to detect the presence of debris and in response, to select a behavioral mode, operational condition or pattern of movement, such as spot coverage or the like. Multiple sensor channels (e.g., left and right) can be used to enable the detection or generation of differential left/right debris signals and thereby enable an autonomous device to steer in the direction of debris.
