Of course, there have been revisions, updates, and color variations over the years but the general styles have been/are the same. I appreciate that continuity in Aerus's products. Instead of discarding time-honored designs just for the sake of change it improves upon its effective engineering which gives it an "air" of reliability and customer familiarity.
Incidentally, Aerus continues to offer its well-designed and efficiently-used floor/rug combo tool and dusting/upholstery combo tool which were first introduced with the Model E in 1954, and in fact sold with the last of the famous Model XXXs.
