Claim:
1. A debris-collecting apparatus, comprising: an input portion; a bagging portion having a hood, an air permeable bag removably positioned lowerly adjacent the hood, an electrically-charged dust skirt configured to wrap around the air permeable bag, and a bagging passage for directing air and debris to the hood from the input portion; the hood having a helical configuration extending from the bagging passage toward the air permeable bag; a draft inducer for drawing the air and debris through the input portion and to the bagging portion; a frame operatively coupled to the input portion, the bagging portion, and the draft inducer; the frame having at least one wheel to facilitate transportation; and a ramp for directing the air and debris away from the hood and into the air permeable bag; the air permeable bag having a smaller diameter than the helical configuration; the ramp bridging the helical configuration and the air permeable bag; wherein the helical configuration of the hood extends such that the air and debris from the bagging passage travel along the helical configuration to a point below where the air and debris enter the hood from the bagging passage and applies a dislodging force on the air permeable bag to dislodge debris collected at an inner face of the air permeable bag.
