Years ago when I was doing Rainbow and Thermax vacuum cleaner demonstrations I never ceased being amazed at how much dirt and dust I saw in most folks homes. Invariably I was able to turn the water muddy in the 2 quart water basin that the Rainbow uses instead of a bag.

Actually, the water always looked like it had been taken from the Mississippi river or a local muddy creek. A major health concern of homeowners today is dust mites. Most people don't realize that dust mites are a problem in the average home.

Dust mites have found a good place to live in the average persons home simply because it's comfortable there for them. Do you know what the dust mites favorite dish is? Human skin, ouch!

Once, I did a demo way out in the country in a real nice upper middle class sub-division. The house was pretty new and had all the earmarks of being clean and nice inside. They had two little pets which also made their home inside the house.

I vacuumed a portion of their carpet like I usually did, turned the water to chocolate brown, then showed them what I had vacuumed up. To say they were disgusted would be an understatement. They were horrified when they looked in the water and saw bunches and bunches of drowned fleas! They saw the need and bought a water based vacuum that night.

Yes, the Rainbow vacuum and the Thermax vacuum does suck up dust mites, fleas, and lots of other nasty things and puts them where they belong... in the water.
