ABSTRACT:
The underside of an escalator or moving walkway handrail is continuously cleaned by an assembly which includes rotating brushes associated with a vacuum nozzle which removes loosened debris from the handrail. The brushes are preferably driven so as to rotate in opposite directions to sweep debris toward the vacuum nozzle. The vacuum nozzle empties into a container which can be periodically emptied during normal servicing of the escalator or walkway.
