ABSTRACT:
The present invention involves a high power vacuum attachment apparatus with infinite adjustability and includes a housing with side walls, a top and a back, and with an open front and an open bottom. A gate located within the housing divides it into two compartments and is slidably mounted so as to be moved up and down within the housing. The top of the housing has an orifice through which an adjustment mechanism passes and is connected to the gate. Preferably, the side walls have a greater width at the open front than at the rear wall so as to taper rearwardly. Also, this attachment may include a vacuum pipe connected to the housing which functions as a handle, a vacuum line and may include an adjustable air valve. In preferred embodiments, squeegees are included along the bottoms of the housing walls.
