发明名称 Gutter and downspout cleaner
摘要 A gutter and/or downspout cleaner employs a water spray and a mechanical snake to break up and dislodge debris. The cleaner is sufficiently long so that an individual who is standing at ground level can arrange the water spray and snake above a gutter or downspout to be cleaned.
