I always do my own chimney sweeping. As we live out in the country, we use standard coal - not smokeless - so there is always a lot of soot when I do the annual chimney sweep. Most of the soot is shovelled into a bucket, but I need a really well filtered vacuum cleaner to clean up the residue. Soot particles are extremely fine, so I need something that will completely filter them out of the exhaust but will not clog. Is this the tool for me?
