"Have you ever seen a grown man spit in the street?”

That is one of the sales pitch used by Rexair to push Rainbow E2 series vacuum cleaners into our homes. The company which has been in business for the past 70 years lets us imagine all the germs that we can inhale from our dirty floor, and they promise that Rainbow E2 will suck it all.

The Rainbow E2 or the Rainbow Cleaning system may not be a familiar household name. It is not sold in most retail stores but is sold the traditional way of going house to house to demonstrate how the product works.
