#48 "It's an amazing machine. So quiet, yet so much suction. Light weight, with large capacity HEPA bags. Love the extra long hose, and very tall extension wand. It will be packaged without the power nozzle, so the consumer can choose which one they want (there are three: compact power head, full size with twin row steel brush roller, full size with triple row brush roller and dirt sensor). Or you can buy the straight suction model with the WOW bare floor tool. Everyone who sees this machine in person, loves it."
You should contact Tom Gasko to ask about the status of the Prima/Wonder. I believe he told me that you can purchase them at the museum. so I would assume that they are shipping them to dealers.
