Quick question. I normally clean from the top to bottom on my chimney. It is about a 30 ft straight run right into the stove. Can I do a bottom up cleaning using the traditional flexible rods using a drill? I would attach the brush head, and each rod, then attach it to the drill and use it like a soot eater on a low drill setting. I would then take apart each flexible rod as I get towards the bottom. Thoughts?
