The Empress One was a deluxe version of the original Mobile-Aire canned ham 1000 series vacs. It debuted in 1965 and featured a combo Vibra-Vac carpet nozzle that allowed the user to switch between Vibra-Beat mode and regular suction only mode. Nice white braided hose and deluxe white tools in a separate carrying case.
The Empress II “Fast Vacs” debuted a few years later…maybe 1968…and were marketed as a “faster” vacuuming experience: on-board Tool Pak, large rear wheels for better traction on deep shag carpets, upfront Control Panel with “radio buttons” to control the suction, nice large upfront power pedal. These were the 1800 series canisters (1820, 1840, 1860, deluxe 1880).
With the arrival of the Roto Matic Power Teams in 1973 (1200 series), Eureka chose three of their canisters to marry with the new power nozzles: a basic 1600 Sweet Sixteen, a deluxe 1600 Sweet Sixteen and a deluxe Empress II Fast Vac in cream green colour.
