Happy with our Eco white goods - although there was an issue with the washing machine gunking up, which turned out to be because it was only ever used on low temperature ... solution was to use a high temperature wash occasionally.
We definitely get clan plates every time from the dishwasher, and the thing uses a fraction of the water, and power, of our old white goods. We used to use the timer on it to come on at night (we had economy-7 tariff, but even if not there is surplus electricity at night so would be doing the environment a favour?? ...) but now we have PV panels so I suppose I should remember to put it on only on Sunny days? :)
My only bug-bear is that the feed to the machines is now cold-only, and we have Solar Thermal Hot water, so get "free" (or should that be "eco"?!) hot water on sunny days and I'd like to use that in the washing machines ... but even if connected to hot feed the hot water would not have travelled in the pipe as far as the machine because it uses so little water that . Progress!
Can't say about Vacuum cleaner though (Seems daft to me for exactly the reason you say, until someone invents a low-power high-suction replacement - that should have come before the ban?? IMO) because we have a central vacuum cleaner plumbed into the whole house. Blinking wonderful, nothing wearing out / clogging up every couple of years requiring chucking it away and buying another to get back to the original "power", and it only needs its "bag" emptying about once every 6 months ...
Can't comment on the kettle either as we don't have one of those either ... we have a Quooker hot tap (outrageously expensive though :( ) which is always-hot. I used to be terrible for boiling a kettle at least half full to get one cup of coffee AND for walking away and coming back half an hour later, by which time it was stone cold, and having to reboil it. Hopefully, now, the stay-hot energy requirement of the Quooker is trivially low so that I am saving significantly on my previous reboil, or boil-too-much-water, bad habits.
Boy's Toys though, of course,and I do like 'em ... :)
