The Lux Guardian shown is like the one I used to have-hated the external filter-it would pop off when the vacuum bumpted into something and wasn't quiet like other 'Lux canisters were.The one I found in the vac shops trade in pile was like yours shown-but yours is in so much better shape!The vac shop one was beat up,dirty,and the filter duct taped onto the machine.And it smelled when you ran it-even with a clean bag.If I can find a clean 'lux like yours maybe I will reconsider it.The vacuum does work well,though.The Guardians have a larger bag so they don't fill quickly with the powernozzle as the other 'Lux machiens using the smaller C bag.
