I would be happy if manufacturers were obliged to publish some agreed
measure of efficiency. Airwatt comes to mind.

Preferably the measurement is made after picking up a few kg of plaster
or other fine dust!

The new EU regs include energy, filtering and cleaning ratings.
Dyson is challenging them in the courts as he doesn't like the
cleaning rating tests.

The main reason I don't have a Dyson vacuum cleaner is because he seems
to be a whiney git.
The idea is to reduce energy use, but how does work if the vacuum
cleaner has to be passed over the same area more often to pick up the
dust? The EU is also on planning to reduce the power of other domestic
devices, including kettles. Now if I wish to boil, say a litre of water
that, is at say 20 degrees C, surely it will take the same amount of
energy whether I do it with a low wattage or high wattage device. Or am
I missing something here?
