The present invention provides a blower-vacuum device with both a blowing mode of operation and a vacuuming mode of operation and having dirty fan operation in the vacuuming mode thereof, which comprises: a hand-holdable unit (10) comprising a motor having an output shaft extending outwardly of said hand-holdable unit; an impeller connected to said output shaft; a first attachment (22, 24, 26, 28) for removable engagement with the hand-holdable unit (10) in the vacuuming mode of operation and comprising both a first volute (22) for enclosing said impeller and a vacuum tube (26) in fluid communication with an inlet of said first volute; a second attachment (16, 18, 20) for removable engagement with the hand-holdable unit (10) in the blowing mode of operation and comprising both a second volute (16) for enclosing said impeller and a blower tube (20) in fluid communication with an outlet of said second volute; wherein the first attachment further comprises a handle (24) on or proximal to said first volute; and the blower tube (20) of the second attachment is coplanar with the second volute (16). Thus the impeller is always easily accessible for cleaning if it becomes clogged with garden waste, the blower-vacuum device may be operated with only one hand in blowing mode and two hands in vacuuming mode and air from the second volute (16) can pass freely down the blower tube (20) without encountering any sharp turns. <IMAGE> |
