I bought the Miele S4 Special Edition 2 months ago. I'm very happy with the purchase. The vacuum is very light, quiet, easy to maneuver and has great suction. The turbo head works very well on my carpet, I can feel the cleanliness of the carpet after vacuuming so there is no need for a power head. The swivel floor brush is wonderful for hardwood floor and the stairs.
