"It amazes me that they went back to a concept (pardon the pun) that they abandoned in the 1920s - namely the pan converter"
That is a beautiful Concept 1, but I must say myself I prefer the Dial-A-Matic. While they do groom the carpet very well, Hoover definitely took "two steps backward" when they sold the design for the DAM to Panasonic and went back to a "dirty air" design. They are definitely noisier than their predecessor. Funny how the U.K. plug sticks out from the housing even when fully retracted. I would have loved to see a Dial-A-Matic II!
