Abstract
A blower vacuum device of the kind having a motor (2) which is located in a housing (4) and which drives an impeller (12) located in a the volute (16). The volute (16) has an air inlet (18) and an air outlet (20). When the device is used as a blower a blower attachment (28), formed in a single piece from a blower duct (28) and a grill (22), is releasably attached to the volute so that the grill (22) is attached over the air inlet of the volute and the blower duct (28) is attached over the air outlet. When the device is used as a vacuum, a vacuum attachment (36) which is formed in one piece from a suction duct (30) and a collecting bag duct (34) is releasably attached to the volute so that the suction duct (30) is attached over the air inlet and the collecting bag duct (34) is attached over the air outlet. This means that it is easy to change the device between a blowing mode and a vacuum mode by detaching a single piece blowing attachment from the device and replacing it with a single piece vacuum attachment.
