My main vacuum cleaner is a Rainbow. It has a water filtration system in it and it traps all kinds of dust and dirt. I can smell the difference in the air after using it (I used it today). I also have an Oreck and a Shark that get regular use for just touchups. The Oreck lives upstars in the foyer by the office and guest bedroom. I only use the Rainbow about once a month, but even when the floors, baseboards, etc. don't look that dirty, that water comes out filthy. It's kind of fascinating and satisfying in an odd way.
