Abstract
A blower/vacuum having an air inlet cover and a blower tube, both of which attach to a blower housing for operation in a blower mode. The air inlet cover is preferably able to removably attach to the blower housing and the blower tube. Blower/vacuums of the present invention may generally prohibit operation unless both the blower tube and the air inlet cover are first installed. The blower/vacuum is further adapted to operate in a vacuum mode by removing the air inlet cover and blower tube and replacing the same with a vacuum tube assembly and a vacuum collection container, respectively.
