I don't have one, but if I did, it would be a disaster by most accounts. I keep stuff out, and scattered in various piles that are only intelligible to me. If I were in charge of vacuuming my box, it wouldn't be done as much as it would if cleaning people regularly did it, but I'd eat something off the floor as long as it wasn't ice cream; but then I'm not a germophobe either :^D
