Abstract: An attachment for a vacuum system which is utilized for cleaning the eave troughs of a building from ground level. The attachment is an arcuately-shaped at least semi-rigid tubular member which connects to an elongated at least semi-rigid extension tube of a vacuum system. The curvature and dimensions of the arcuate attachment allows the operator of the vacuum system to raise the arcuate attachment up to the eave trough and insert the free end thereof into the trough for purposes of cleaning the same. A mirror is mounted on the intrados surface of the arcuate attachment, which allows the operator standing on the ground to view the inner bottom surface of the trough which is being cleaned. The operator of the cleaning system can move the attachment through the length of the eave trough and suck all of the debris therefrom, while watching to ensure that no debris is left behind. The free end of the attachment tapers to a smaller diameter to facilitate mounting of other attachments thereto.
