The last time i had a Factory Rebuild was in 2008,,,they sent the machine back in beautiful condition,(it is a Classic Omega),,they do nothing to the belt lifter for whatever reason, not even buff it, or replace the logo sticker ,so, if the belt lifter needs work, or replaced, point that out ahead of time when you send the machine.
Also, the bottom cover of the Sani Emptors are now all black,,no corresponding colors. All 500 machines will come back with tan colored parts, bag and trim,,and also all machines that are sent in with a hose will get a black replacement hose and coupler,,no corresponding colors.
The one piece long strait and curved wands are now discontinued, as well as the long flat floor nozzles and wall brushes,,,they will be replaced with black G series ones. Infact, any basic attachments that are sent in will be replaced with black G series attachments.
They did send a new dark brown cord back with the Classic Omega,,but a friend that sent in a Classic 3 after i sent mine in, said they sent him a black cord, and also did put a metal Classic Omega belt lifter (unpolished) with a red sticker over where the "Visabelt" window used to be on the front.
So, evidently they are using whatever parts are avalible,,and many older parts are just history.
