Some go up as far as 2200W
The issue isn't as clear cut as the tabloid papers in the UK in particular would have you believe.
The EU's actually moving to a situation where they're going to be labelling vacuums in accordance with how powerfully they suck up dust and how well they clean rather than just the power consumption of the motor.
Over the last couple of decades there was a bit of an arms race between vacuum cleaner makers here where they started advertising wattage of their motors. Some companies, notably Dyson and Nilfisk didn't really participate in it, although Miele (if you pardon the pun) got sucked in.
If you've got a poorly designed filtration system, particularly a badly designed HEPA filtration system, the one way to make the whole badly designed pile of junk actually suck anything up is to jam in a huge motor. That's what a lot of cheap machines were doing.
The other issue is that you can design machine with small, relatively inefficient fans and still achieve high suction by just spinning them extremely fast. That results in a small, noisy vacuum which consumes a lot of power but doesn't suck all that much.
For example, the entire Dyson range is all <1400W
Nilfisk has machines that perform excellently at <1200W
The quirky and famous British "Henry" range from Numatic is only 850W and does an excellent job.
Also, a lot of commercial vacuums used for cleaning in hotels and offices are considerably less powerful (motors anyway) compared to their domestic counterparts. Many commercial machines are <900W.
So, I think there's some method to the EU's assumed madness.
I think cutting the limit to just 900W in 2017 is probably a bit too tight, but it'll be interesting to see what happens over the next while.
Companies like Miele produce 2200W machines that are also very well designed from a technical point of view. My question though is if those machines are actually needed. I find at maximum setting our Miele actually just sticks to the floor, especially on carpet. Our old 1600W Miele and our 2000W Miele in my experience perform almost exactly the same. I can see really no great advantage to the 2000W version and we use them both interchangeably all the time.
I honestly think that a lot of the wattage stuff has been about marketing and not about how well the machine actually works. Similar to the way that some people just want a car with a huge engine for no logical reason.
