Abstract
A sewer-cleaning tool includes a sleeve is sized to have an inside diameter incrementally greater than the outside diameter of the pipe. A sleeve is sized to have an inside diameter incrementally greater than the outside diameter of the pipe. A scoop, having a spoon shaped main body, is carried by a lower portion of the sleeve. A fence assembly includes left and right fence segments attached along their lower edges to the scoop and at an upper rear location to the sleeve. A reinforcement assembly includes left and right rods connected to an upper and forward location on the left and right fence segments, respectively, and to the sleeve. In operation, a water hose delivers water upstream of the cleaning tool, causing debris to be washed to the tool and evacuated, while the water moves through the fence assembly, increasing the ratio of debris to water collected.
