Abstract: The Gutter Leaf-Blower is an apparatus conceived to clean rain gutters. The objective is to provide the operator with a ‘user friendly’ means of blowing leaves out of gutters while operating from ground level. The objective was accomplished by mounting an air nozzle on one end of a small lightweight, 6-8 foot rigid tube assembly and, in turn, connecting the input of the air nozzle to the output of an air blower with a flexible air hose.
