Rainbow home cleaning system?

I need a really good air purifier and I have heard a few people tell me about a Rainbow Air Purifier. I already have a Kirby and I hate the thing. Does anyone have a Rainbow? Does it really do everything? Vacuum, deodarize, purify, humidify, sweep, dusting, mop, and carpet cleaning? someone said it even gets inside of dryers and can clean the lint out and under the fridge so you dont have to pull it out. sounds to good to be true...
