It’s obvious, they should just rate all vacuum cleaners by efficiency.
Publish a “suck per watt” number for each model and then increase that number year by year just like the auto CAFE standards....:^)
They are way ahead of you. From the article: "The wattage will be limited to only 900 watts by 2017 –..."
The last paragraph stated that the government was there to help, and since you were too dumb to research crappy vacuum cleaners on your own and ended up buying one, the heretofore unregulated industry will now be regulated[ so everybody will have to buy an even crappier by design model].
