Rainbow vacuum cleaner (the e series) is the one i bought, this thing is a expensive piece of junk. The cord is so cheap it gets very warm during use, it does not pick up things off my carpet near as good as my much much cheaper sears vacuum, so many times i have to loosen things on the rug before the rainbow will pick it up, so i get out my 200 dollar sears and get the job done.
I learned a very costly lesson and am letting everyone i can what a waste of money a rainbow vac is!
