ABSTRACT:
Dust collection apparatus is disclosed adapted for both vacuuming and blowing/sweeping functions. The apparatus consists of a single, self-contained unit comprising a blower, a cleaning hose, an engine, a collecting area, inlet and outlet passages, and a switching valve which can switch the internal airflow so as to convert the cleaning hose from a vacuuming function to a blowing/sweeping function.
