If you set a limit on power consumption, decent makers will produce a

But that still may mean that the best is not as good as one of equal
efficiency, but a little more powerful. The rules should have been about
efficiency, not maximum power. We don't set a maximum power for washing
machines, dishwashers, microwaves, light bulbs, etc., but grade them on
efficiency and even ban the sale of the less efficient models. What
makes vacuum cleaners different?

It doesn't. The limit is for domestic vacuum cleaners. So in the same way
as you might want a 500 watt light source in your bog, you can buy a
vacuum cleaner which uses more power than the domestic limit.

You can't just nip into your local shop and buy one though. They are
simply not available in normal high-street shops.
