Rainbow vacuum cleaners are so ridiculous. My parents let themselves be conned into buying one of those. I remember the sales person leaving the vacuum with us on a Friday to test out for the weekend. I was like, "Why are we going to test it out? It's $1300. We're not going to buy it. Even if it was wasn't an unbelievable rip off, we can't afford a $1300 vacuum." Then I remember coming home from school on Tuesday and asking why the vacuum was still there . . . I thought we only had it until Monday, and my Mom said she decided to buy it. I was only fifteen at the time and I remember actually feeling almost ashamed. I couldn't believe that my parents could have made such an astronomically stupid decision. You gotta understand how poor they were. I mean, we're talking about a single-income family (~$40k/year) with up to ten kids at the home at any given time. I could figure it out exactly, but when we got the vacuum it was probably around 8 or 9 kids. And my parents didn't take any government assistance. No food stamps. No Medicaid. I mean, we got things like free lunch at school, but none of the big ones. We struggled.
But aside from them being outrageously priced, they are a pain in the ass to use. You have to drag around this ridiculous rolling cylinder behind you that is filled with water. Then, after you vacuum, you have a cylinder filled with a disgusting water/dirt mixture. Shardian nailed it already. He's got this $1300 vacuum that "works great", which he deliberately avoids using. That sums up the Rainbow vacuuming experience. And whether you paid $20 for it or $1300 for it, either way it just sits in a closet unused because who can be bothered to use it as anything but a last resort?
