Safest vacuum for soot
"This is the Cadillac of vacuums for heating appliances, chimneys, and more. Double filtration means no nuisance dust. The Sootmaster is tough — no thin metal here. Just about every part is metal. If you have ever had the unfortunate experience of an ember catching the paper vacuum filter on fire, then you can relate to why it is the safest vacuum because it is made of steel, not plastic. A well built vacuum that you will have for years."
