My parents have a Miele that is over 20 years old and still works like a dream. I have a much cheaper Miele that I've had for 8 years now and it works amazingly well. Theirs was close to $1000 and mine was around $400, if you are looking for price info. We have a double-coated dog that sheds outrageously, all hardwood flooring, and a mix of low and high pile rugs throughout the house. I'd highly recommend a Miele. I've never had long term luck with a carpet sweeper.
