This is an old trick.  Chances are that ANY vacuum cleaner will pick up SOME 
dust after any other vacuum cleaner.  This might be hard to demonstrate with 
your Sears, because the dust goes into a bag, where it is hard to find.  But 
I'll bet the demo machine would pick up more dust after itself.

I used to see this method used to sell press wash to printers.  Wash up the 
press with what you're using now.  Then we'll wash it up with this 
"super-duper" press wash, and you'll see that we got off some ink that your 
stuff wouldn't touch.
