I have a Rainbow two speed bought brand new in 2006. I've used it quite a bit the first couple of years. I still use it SOME. The entire machine and the hepa filter still look brand new. Based on some folks saying that the dust just skips over the water and that they don't filter well always confused me......If that were the case, I would think as many times as I've used it the filter would be nasty, but it still white and even smells new.
I always wondered about the other water filter vacuums. Did they copy Rainbow?
I saw a Thermax once in a thrift store. It was HUGE.
