ABSTRACT:
A portable hand-held blower vacuum apparatus (10) having a hinged inlet cover (24) with a handle (26) disposed at one end of the cover (24). The cover (24) is moveable between a closed position where the cover spans an air inlet opening (20) and an open position to allow insertion of a vacuum tube (50) in to the inlet opening (20). The handle (26) is used to move the cover between the open and closed positions. Air flows into the inlet opening (20) through a screen (38) in the cover (24), through arcuate slots (42) in a tubular extension (44) of the inlet opening (20) and over a circumferentially extending rib (46) formed on the cover (24). In an alternative embodiment, a dedicated blower is provided in which a solid, stationary cover (54) spans the inlet opening (20).
