I haven't posted much but have received a lot of good information from you guys! Anywho, we live in an old 2 1/2 story farm house with a steep roof. I went up and cleaned the chimney this fall when it was nice out but it was a bear. Does anyone have any recomendations of a unit that would work from the inside of the house. I'd feel better if I could hit it every once in awhile. I'm using a wood burner that enters a square chimney through a 6" pipe and there is a larger, probably 8" cleanout door at the bottom. Not sure if there is a fiberglass rod that I could shove in there or not.
