Hey Shawn.
Mate, you guys have nothing to worry about, you already lead the world. Becuase of your 120v system and the many old buildings you have with 12 amp circuits, most US manufacturers will design their vacuum cleaners to respect the 12 amp limit. This means that no vacuum cleaner motor on general sale in a US department store; among other household vacuum cleaners will exceed 1440watts consumption at peak.
120 vollts x 12 amps = 1440watts.
You are basically already there. And so you should be you invented this stuff. Ohio is the cradle of life for the vacuum cleaner industry in many ways. And your best (and most expensive machines) are and always have been super energy efficient anyway while being solid machines. The Kirby cleans carpet better than anything I have ever seen, and it consumes just 635watts.
Nothing to see here..... Move along.
