I'm interested in getting a Soot-Eater to clean my own chimneys, but I don't know how hard it would be to clean the Morso 5660 from below. I thought I would be able to find a video showing how to take off the baffles, but haven't found anything so far. We will be getting a metal roof soon, and I don't know how dangerous it would be to tackle this from above. Any instructions or suggestions here? I've gone from "no way would I do it, I'm hiring a professional" to thinking maybe I could DIY.
