At best, they can only expect energy use to break even. Folks will just vacuum longer to get the same result.

That’s the beauty of capitalism.
Exactly.
But if you were in the market for a new one, now or in the next couple of years, I’d say move on it now. And find the money to buy a premium quality model. A luxury vacuum. They last forever.
Find the specs. There are plenty of review places out there. Power consumption does not reflect suction or cleaning ability. You need to find brush speed, bristle hardness, weight, CFM, and inches of water lift for the suction. Plus noise. Most of these specs are required by law in Germany, but in few other places. So vacuum shopping is literally an incomparable process, just like mattress shopping. Don’t rely just on Consumer’s Guide.
Been there, done all that, bought a good one, will keep it for at least 2 decades.

1440 watts is the highest that you can get out of a 15 amp outlet here in the states and still get UL approval.

Man we would have killed to have a 2400 watt limit like you can do in europe.
