Recently, for reasons I shall not mention on this hand tools blog, I retrieved my old Fein Turbo II (model 9-55-13) shop vac from storage, where it's been for the last 13 years.

You'll know it is if you get black foam bits coming out of the exhaust." Well guess what - he was exactly right.The Fein shop vacBits of black foam all over the floorHe said that happened to his Fein Turbo...
