> I'd say no and this is why rules restricting how powerful the vacuum cleaner can be is stupid

Before the rules, manufacturers were advertising vacuum cleaners with ever larger wattage numbers. They weren't actually any better at picking up dirt, they just had less efficient motors.

I would have preferred consumer education (e.g. require suction/CFM numbers to be shown) but banning pointless wastes of electricity in the name of marketing isn't as crazy at it may seem.
