What a nifty little tool. Easy to snap together. Slides right up the chimney. Turn on the drill, slowly retract the sweeper down the pipe, removing a leg of the total length one at a time as you go along. Soon you are at the bottom. Collect and remove any buildup that fell down. Repeat often. Why not? So easy. Enjoy the satisfaction of accomplishing the job, preventing pipe fires, and saving a good share of money. Cool tool.
