Oh good lord, well il be sure to keep the one I have with it, well , with it. If thats the original then its my idea of hell. I hate articulated floor heads, god knows why you see them so much, I find them quite awkward to use.
Interesting way of installing the paper bag though, I would of either opened it our fully and inserted the ring into its seatings in the cloth bag ring thus trapping it in tightly or fed it thru the hole as he does and still trapping it between the ring and cloth bag. seems odd to just push it and and shut the lid.
