This works on the same principle as fractional distillation. Material sucked in is blown through a vertical column with a series of side vents: lightweight dust is drawn off at the top, food and coins fall to the bottom and everything in between goes into a separate lint bag. After a while you get the stuff back in little bales, or pressed into a sheet of felt, to be used for clothing, fuel, or building materials, or woven into a new carpet.

       This would be spectacularly useful, especially for police forensics.   

       What if there was a dial on the side that could be set to filter off certain strata; drugs, hair, skin flakes etc?

       This is good. The only problem I can see is that 'vacuum cleaners' violate the laws of physics. Crack that, though, and I think you'll have a winner.

       Nice idea--there was an idea for harvesting dryer lint a while back, and this dovetails nicely. I want one fitted to my reduced-pressure-atmospheric-reverse-blowing cleaner right away.   

       [Addendum: I'm damned if I can find an idea for dryer-lint harvesting. I thought...I mean I was almost sure...time for one of the blue pills, I think.]

       even better, use the fibers to make-- fake sleeping cats!

       That would work. Most of the debris removed from my carpets seems to be cat fur. (And there always seems to be more fur than I have cats...)
