I grew up with a Rainbow in our home. My parents didn't have a lot of money so they bought the model that the guy used for demos. My mother still has it.

This always impressed me; despite the fact that as a kid I hated the vacuum because I was the one that got the impressive job of emptying out the water bin. As an adult I have asked to use her Rainbow many times.....particularly when the $200 vacuum we bought a few months prior just quit sucking.

So when a friend asked me if I was interested in sitting through a Rainbow demo, I jumped at the chance! Of course, I had an idea of how much...
