ABSTRACT:
A method and apparatus for sweeping seating areas is provided which enables the operator to stand substantially upright while directing a stream of air substantially horizontally along the floor supporting the seats. The apparatus includes a handle adapted for connection to a source of compressed air, a substantially elongated wand connected to the handle, and a nozzle which directs a stream of air along the floor substantially perpendicular to the wand. The nozzle is configured to intake additional air besides the compressed air supplied through the handle to provide increased air volume at pressures reduced from that supplied by the compressed air source. The method includes positioning the apparatus behind seats, particularly in stair-stepped stadium seating areas to provide a substantially horizontal air flow reaching into corners between the riser wall and landing of the seating area and around the bottoms of the seats.
