I have some of the bags for these however I want to preserve them for display so I took the regular Oreck bags and cut the cardboard collar to fit these 4000s.
My orange one does have a broken clip but that's ok.
I do have a whirlpool cvr (I forget if it's 1,000, 2,000, or 3,000) It's black.
Stay tuned for a service project post of the cvr Whirlpool eventually
The blue one with plaid bag has a new old stock brush roll in it. What belts do you use? I actually found that the Bissell steam cleaner pump belt worked pretty well.
