Abstract
Abstract A cleaning device for removing leaves and other debris from elevated structures such as gutters. An elongated support handle is provided with a quick-release coupling at an upper end thereof. A curved support member is removably secured to the elongated support member and has a power means, such as an electric motor provided at an opposite end thereof. A shaft extending from the electric motor is provided with a plurality of elongated, flexible elements to engage, dislodge, or comminute leaves and other debris in gutters or other elevated structures during operation of same. Universal joints along the curved upper support member permit the placement of the power means in such fashion to move under nails or the like that are used to support the gutters and secure same to a housing structure. Normal operation of the power means disposes the shaft vertically with the elongated, flexible members rotating in a horizontal plane. The support elements may be tubular in construction, and a further attachment provided for the elongated support to seal an end of a downspout from a gutter, whereby water may be forced through the elongated support member and into the downspout to clear same of debris, if necessary.
