When I moved house, I was in a position where I needed a new vacuum cleaner. I had a cordless Dyson. It was very clever, light and swishy. But, it broke - a key piece of plastic snapped in a way that was entirely impossible to fix without buying a new machine. After considerable research, I came to an odd conclusion. Despite the fact this little fella contains a heck of a lot of plastic, he's a lot more sustainable than many others on the market.
Energy efficiency is not an easy thing to calculate with a vacuum cleaner - as so much of the "efficiency" is down to how you use them. But I *can* tell you what's not
efficient - vacuuming half your house then having to put the thing on charge for an hour then finishing it off later!
