"what price a low energy usage cleaner if you have to vacuum the same bit of carpet twice?"
Like the way most toasters are "low energy" nowadays. They take twice as long to make the toast so you end up using the same energy (or more, due to wasted heat emissions rising up) to make toast that is hard and dry. Unfortunately, you can't test a toaster until you get it home.
This does seem to be an unfortunate trend. Setting headline targets for energy efficiency which result in more usage rather than less due to the manufactures gaming the system either to save money or because the targets are unrealistic in the first place.
