I want to say Blue lustre, but it could be Rug Dr. they both have been around for a long time. I remeber reading an ad or thread here or somewhere not so long ago about using a shampooer then extracting with xxx machine(like a wet vac). I think what I had seen was a late from the 50's. Mabe im loosing it lol, but I do remember seeing something about extraction from the 50's
