Hello,
As with everything, things are more complicated than they appear. I suspect you can make a 100 W motor and fan unit to suck like a hurricane, if there is no resistance to the exhaust, but we have to suck through a series of filters, or else the dust just gets sent straight back out. I agree that the measure of motor power is not the best way to rate hoovers performance, but neither is suction in CFM, nor any power rating such as air Watts, unless there is some qualifying factor. If my vac filters down to .5 micron, it may well have a similar suction to one that only filters down to 2 mic and runs on half the motor power. It is not just about relinquishing dusts hold on the carpet! Although the build quality and replacement part availability of old machines is second to none, and I wish there was a return to such (longevity of products is probably more environmentally friendly than limiting motor size, but the EU won't legislate for this) I doubt the engineers who designed these machines had computer modelling to aerodynamically engineer the components as modern machines might have. Although there is always room for improvement, I suspect that good quality, modern machines have more efficient use of power than old things do. I also doubt that the EU bureaucrats (male?) who decided on this legislation have even seen their au pair use the vacuum cleaner in their homes! I'm all for saving the planet, but I think this is all a bit lame. There needs to be a concerted effort to develop clean renewable energy so we can live our modern lives, which is also a consequence of the rules they pass down to us.
Will there come a time that the EU will ban home workshops? If I add up the number of Watts my machines used and its effect on the planet, it would make a mockery of the few used by my Hoover to keep my home clean. Let face it, I can buy all the furniture I need from Swedish home furnishers, for almost no money, so my workshop is essentially an unnecessary indulgence.
Mike.
