This latest Dyson is highly significant in the vacuum-cleaning world. The V10 marks the end of the line for mains-powered, corded Dyson vacuums. From now on, Dyson says it will only develop the cordless variety, because the V10 is now as good as – even better than – a mains machine. You can see why that’s plausible. It’s only 12 years since Dyson first made a battery-powered vacuum. It had a “digital motor” (a term that still makes some engineers giggle but I have been convinced is more than a marketing term) weighing 150g and producing 85 air watts of suction.
Around £350m of development and 900 patents later (seriously, vacuum tech is a cut-throat world) the new V10 motor weighs 125g and produces 290 air watts. Built by a line of 300 robots in Singapore, it has a ceramic motor shaft, half the density and twice the hardness of steel. The V10 even has sensors to detect barometric pressure and temperature sensors to ensure it works at the same power in the Himalayas as at the Dead Sea. It is 20 per cent more powerful, Dyson says, than the earlier V8 model, and dust unfortunate enough to get sucked up is subjected to a force of 79,000 g – bearing in mind that more than about 6 g on a rollercoaster is enough to make you pass out. Oh, and the bin is 40 per cent bigger and has a clever mechanism that makes it possible to open the unit when it’s deep in a rubbish bin so you don’t end up inhaling half the dust you vacuumed.
And my cleaner’s verdict? It’s even better than the £289 Bosch Athlet, which it’s often compared to. I have to say, I also find it very quiet and almost effortless to use.
