ABSTRACT:
A debris collecting apparatus includes a debris conduit (2) one end of which is an operating end (4) and the other end of which is a collecting end with a collecting bag (6) attached thereto. An impeller (8) discharges air into a straight part of the conduit. A switch arrangement is provided to switch the air flow between first "vacuum" flow in which air discharged from the impeller induces an air flow in the debris conduit (2) from the operating end (4) to the collecting end and a second "blowing" flow in which air is discharged from the impeller through the operating end.
