Does anyone remember what Royal's first heavy duty commercial upright cleaner was? I want to think it was the model 606, introduced in 1965.
However, the straight-suction model 130 (which evolved into the 311 in 1965) might be the very first of these, and it dates from before or during WWII. However, I still consider the 606 (and the 606A with the flip-top headlight) to be Royal's first revolving brush commercial upright cleaner.
