Hey Derreck~
Try running the tools through the dishwasher... I hear that works wonders!
The switch on that looks to be original. There was a batch of them that had a rocker switch instead of the regular, trademark Hoover flippy toggle switch. My guess is because of the increased amperage these cleaners pulled, a different, beefier switch was necessary.
In fact, that cleaner is the same one that we have under one of our workbenches at the store. Under my workbench is a minty green and chrome Celebrity QS. Both clebrities have seen waaaay better days, and have been rebuilt mutliple times. But, if you think about it, they probably get used (on and off, on and off) for about 20-30 minutes or so a day, 5-6 days per week Those Celebrities were great cleaners, and although eventually the suction power will decrease some, those held it pretty well as the bag filled up--I heard an old-time Hoover rep saying once that when the Celebrity first came out, one of the demonstrations they woud do was to take a bag of flour, and vacuum it up... then let customers feel how the suction didn't decrease a whole lot.
As far as Celebrities go, that style of them is not at the top of my list... I mean, they're awesome machines, but looks-wise, they don't send me. I love the chrome QS series, and the plain, flat, floaty ones.
And my only issue with that particular style of model is the three wimpy wheels that are on the underside of the cleaner. Not the easiest to maneuver.
I'll try to post some pictures of the Celebrities I have in my collection.
