Abstract
A portable rechargeable battery-operated slender tubular blower for removing relatively light debris from hard surfaces such as sidewalks, driveways, decks or workbench surfaces. The blower uses an axial flow blower fan arranged for noise minimization and energy efficient operation. Blower tube inlet and outlet portions are arranged for debris removal effectiveness by optimizing airflow volume and velocity parameters.
