Some of the best vacuums ever built in the USA used 575 watts. I'm talking about the Electrolux of course. From the model 30 through the Diamond Jubilee, the Electrolux motor (which was MORE than powerful enough) didn't consume tons of electricity.
My favorite vacuum of all time, the Air-Way model 88 Mark II with RugMaster Power Nozzle consumed just 900 watts. And that's a 2 motor set up.
My second favorite vacuum of all time, the Rainbow model D consumes 700 watts, with amazing, constant airflow and suction.
The USA never had vacuums that used over 1200 watts that I'm aware of. We are restricted by 1500 watt circuit breakers and 120 volts max.
