1. An autonomous cleaning apparatus comprising:

  • a chassis;

    a drive system disposed on the chassis and operable to enable movement of the cleaning apparatus;

    a controller in communication with the drive system, the controller including a processor operable to control the drive system to steer movement of the cleaning apparatus;

    a cleaning head system disposed on the chassis having a cleaning pathway providing pneumatic communication with a debris bin, the cleaning head system comprising an agitating brush configured to throw debris into the debris bin;

    an indicator light; and

    a debris sensor in communication with the controller, the debris sensor responsive to the debris to generate a signal indicative of passing of the debris;

    wherein the controller is configured tochange an operational condition of the cleaning apparatus in response to receiving the signal generated by the debris sensor, the operational condition selected from the group consisting of a speed of the movement of the cleaning apparatus and an amount of power drawn by the cleaning apparatus, and toilluminate the indicator light in response to the signal generated by the debris sensor.
