The roof gutter cleaning brush has a head which is supported by a tubular frame, whose length is matched to the distance between the gutter and the ground level. From ground level, an operator can carry out cleaning work with a draw line coupled to the effective link system of the brush head. The draw line imparts a swinging movement to the brush head so that the head point follows the gutter bottom surface, thereby removing collected contaminants. When the operator has taken up the position for cleaning, the brush rests partly with its support arches against the outer edge of the gutter and partly with its frame in a body support against the middle of the operator. |
