Not Mine, but Worth Showcasing

I did some heavy duty Christmas cleaning for an old family friend yesterday and today, and this is her vacuum: the Aerus Lux Classic.

This is virtually identical to the previous flagship base models, namely the LE and Ambassador, save for the different, more powerful, and louder motor. I used the Classic for dusting, stairs, bare floors, and baseboards. For carpet (my friend has it almost wall-to-wall), I brought along my battleship grey Epic 3500 #2. 

Here is the only (external) difference I can see between the Classic and it's predecessors: this (permanent?) post-motor filter. I don't recall seeing one of these before.
