    a debris sensor in communication with the controller and proximate to the cleaning pathway, the debris sensor responsive to debris passing through the cleaning passageway to generate a signal indicative of such passing;

    wherein the processor directs the drive system to steer the cleaning apparatus in a localized pattern of movement substantially immediately in response to receiving a debris signal generated by the debris sensor; and

    wherein the debris bin is removable from the cleaning apparatus in response to the debris sensor for dispensing of collected debris.
