FWIW Jet has a normal looking DC with pleated filter that has some kind of "Vortex" panel between the dust bag and the pleated filter. I think it keeps the pleated filter cleaner longer but all of the dust still ends up having to be emptied at some point.
The Jet with Vortex might eliminate the fine dust getting into the canister however. AND all dust goes into a single bag. You don't need extra space and or an extra dust container.
Leon, Aaron - I just bought the Jet.
