Lower power vacuums are like less energetic fuel and low gallon toilets. It just takes more gallons and more flushes to get things where they need to go. The energy consumed is almost the same.
More fools.
Or like putting 10% Ethanol in gasoline- you get 10% less energy per gallon.
Like the push for tiny car engines that actually burn more fuel for a given trip than a bigger engine under less stress.
I was wondering the same as low energy toasters. Do they believe people 2ill just eat half toasted bread? Its silly.
