Abstract: A cleaning robot system including a robot and a robot maintenance station. The robot includes a robot body, a drive system, a cleaning assembly, and a cleaning bin carried by the robot body and configured to receive debris agitated by the cleaning assembly. The robot maintenance station includes a station housing configured to receive the robot for maintenance. The station housing has an evacuation passageway exposed to a top portion of the received robot. The robot maintenance station also includes an air mover in pneumatic communication with the evacuation passageway and a collection bin carried by the station housing and in pneumatic communication with the evacuation passageway. The station housing and the robot body fluidly connect the evacuation passageway to the cleaning bin of the received robot. The air mover evacuates debris held in the robot cleaning bin to the collection bin through the evacuation passageway.

Abstract: An autonomous mobile robot includes a body, a drive supporting the body above a floor surface, a light-propagating plate positioned on the body and having a periphery defining a continuous loop, light sources each being positioned to direct light through a portion of the plate to a portion of the continuous loop, and a controller to selectively operate the light sources to provide a visual indicator of a status or service condition of the autonomous mobile robot. The drive is configured to maneuver the mobile robot about the floor surface.

Abstract: This document describes a mobile cleaning robot including a chassis having a forward portion and an aft portion; a blower affixed to the chassis; a bin supported by the chassis and configured to receive airflow from the blower, the chassis enabling evacuation of the bin through a bottom of the robot. The bin includes a top, a bottom, a sidewall, and an internal barrier. The bin includes a first volume and a second volume separated by the internal barrier and a filter unit supported by the internal barrier and removably disposed in an airflow path between the first volume that includes an intake port in the bin and the second volume that includes an exhaust port in the bin.
