Abstract: A power broom with a transverse auger and vacuum debris conveying system especially well-suited for removing gravel or other debris from a flat, built-up roof or the like, and for conveying the loosened debris from the roof. The power broom includes a horizontal, rotary brush for dislodging gravel, dirt, and other debris from the roof and for propelling the debris within an enclosure substantially surrounding the rotary brush toward the auger which in turn positively conveys the dense gravel particles and other debris toward a vacuum pick up point within the brush enclosure where high velocity air from a vacuum source readily picks up and conveys the dense gravel particles from the power broom to a collector via a vacuum hose. The power broom is further provided with a handle assembly which is selectively operable to simultaneously disengage the power drive propulsion system of the broom and to raise the rotary brush clear of the roof.
