Rainbow Storage
Austin,
One of the founders of the VCCC and long time friend, Clay Floyd, is a Rainbow distributor in Lenoir, NC, just up the road from me.
I leaned a LOT about Rainbows/Rexairs from him as he has been in the business over 30 years. Anyway, he told me that when Rainbows are demonstrated in the home, the salespeople tell you to store the water pan separate from the main unit as the pan tends to hold moisture and eventually the motor can rust from the inside out and the gaskets will rot as well. I never knew that because I never bought a Rainbow from a Rainbow salesperson.
He also said how they instruct you to cleaner the separator after every use. Sometimes it is referred to as the "spinner". I never have had to clean any of mine since my house was not that dirty and I was not picking up anything that would not go right into the pan.
Most Rainbows owners that I have talked with that are normal people, meaning not vacuum enthsiasts, like one thing the most about their vacuums and that is the instant gratification of seeing what comes out of their carpets and off their floors!
Clay did also tell me for maximum performance that as soon as you can no longer see through the water it is time to change it. The flaw with Rainbows is that as the water evaporates from the air flow, if it becomes too saturated with dirt, it can be blown back into the air so keeping it clean is imperative. Rainbows are not able to let certain kinds of fine dust, like talc, mix with the water in the pan, so talc would blow right out through the exhaust.
For most general cleaning, this would not be a problem. If you come to the convention in St. Louis, Clay is planning on being there and you can ask him all kinds of stuff about Rainbows as well as other vacuums. He is one of our the most knowledgeable members.
