发明名称 Self-cleaning gutter guard
摘要 A device mountable to a gutter for removing debris therefrom includes an elongated shaft with proximal and distal end portions positionable within the gutter, a plurality of debris-removing members mounted about the shaft and between the proximal and distal end portions thereof, a plurality of brackets spaced along the gutter for receiving the shaft therethrough, and a mechanism for operating the device causing the debris-removing members to rotate in a select direction as desired by a user. The operating mechanism may rotate the debris-removing members in an oscillating path or unidirectional path and a sensor may also be included to selectively toggle the device between on and off modes, without direct user input.
