Abstract
A blower/vacuum having an air inlet cover and a blower tube, both of which attach to a blower housing for operation of the blower/vacuum in a blower mode. The air inlet cover may removably attach to both the blower housing and to the blower tube. In some embodiments, operation of the blower/vacuum may generally be restricted unless both the blower tube and the air inlet cover are first installed. The blower/vacuum may further be 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.
