I have one. I think it came out in the late 80s or early 90s and was sold in vacuum stores. It has a one speed motor. I guess it was Filter Queen's attempt at filling a niche with those who prefer a bagged vacuum cleaner. The motor unit sits in a tub like all Filter Queens. But instead of a cone that filters fit onto, there is a cage that protects the motor unit. A conventional dust bag is then fitted onto a redesigned hose inlet. I thought it was a poorly conceived design on Filter Queen's part (which may explain why they were short lived). So I converted mine over to a conventional Filter Queen setup (which was easy to do with the right parts). I use it out in my garage to vacuum debris when I polish aluminum castings.
