1. A robotic cleaner maintenance station, comprising:

  • a station housing and a platform configured to support a robotic cleaner during servicing, the station housing defining an evacuation passageway exposed to the robotic cleaner, for evacuating debris from the robotic cleaner during servicing;

    a collection bin removably attached to the station housing, the collection bin being in pneumatic communication with the evacuation passageway and configured to be disengaged from the station housing in a vertical direction relative to the station housing;

    a filter arranged to filter air passing from the collection bin to outside the maintenance station; and

    an air mover configured to draw air from the evacuation passageway and into the collection bin to evacuate a robotic cleaner supported on the platform, wherein the air mover comprises a bagless cyclonic vacuum configured to divert debris from an incoming flow using centripetal acceleration of the debris.
