Yep
blows my mind to but in a way I can sort of understand it. I think the demo's may not really touch much on the maintenance of the machine because they are trying to sell one. Even though they state in the manual to clean separator often, change water before getting too dirty....I think maybe most users think "fill with water, vacuum until done, dump the crud...done." In fact,when my grandma had her Rainbow from the 80s and we used it, that's what we did. Filled with water and I remember taking the basin out and dumping the dirt in the ditch and it was thick. I mean, we took care of it but didn't realize the water needed to be changed much more often than we were. God knows what the inside of that thing looked like. We were abusing it without realizing it. That's why I would be paranoid to buy a used one unless you KNOW it's been totally serviced inside and out. They can look so CLEAN outside but be filthy inside.
