Does anyone have a complete timeline of Electrolux/Aerus commercial UPRIGHTS? Thanks, John, for informing us that both the commercial Model CB2000 canisters and the uprights were sold concurrently (reply #42) through 1999. I've noticed that many of the uprights were color-coordinated with the tanks and triple brush machines but there are some, such as the Prolux machines, Electrolux Commercial, and Lux Commercial that were charcoal and red (which would only have partly matched the machines of the Renaissance/C104A era.
Also, I have seen 1400 and 1400X and am wondering if those were model designations or names.
