I have a sooteater, but clean my flue from the top down, so no problem with debris getting into my drill. The instructions talk about putting a plastic bag with a hole in it for the rod to go through when you clean from the bottom up. I wondered how you would keep the bag from getting wrapped around the spinning rods, but maybe if you used a thicker bag that wouldn't be a problem. Others have mentioned cutting a hole in a large plastic jug to catch the soot falling down the flue. Either of those methods would likely eliminate or greatly minimize the problem of soot getting into drills. Also, if you have access to an air compressor you could always blow out the drill when you finish.
