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 debris removal effectiveness by optimizing airflow volume and velocity parameters.

An electrostatic precipitator is disclosed which is provided with a plurality of gas jets which upon activation repulses the normal gas flow through the electrostatic precipitator during cleaning to create a quiescent condition to reduce further dispersion of the loosened particulate layer into the outlet stream. A control system for operating the jets and the discharge and collector plate rappers is shown.
