I was wondering if anyone knows how a Dyson compares to a Rainbow? My mom & dad recently bought one (Rainbow) last year. They had an appointment set up for someone to come into their home to do a demonstration. When I went there after work, the girl was still there...and I could tell that my mom had purchased it. After the representative left, I asked her what make her buy it, since she had previously told me she wasn't going to buy one. She said, "I saw what it did". She said she had vacuumed the area rugs before the girl came, and the girl used the Rainbow and picked up ALOT more cat hair as well as dirt. The Rainbow cost them almost $2000!!!
