DYSON UPGRADES VAC RANGE

They've reinvented the duster, crevice tool and on/off switch!

One thing that has always defined Dyson's cordless vacuum cleaners is that you activate them by pulling a trigger. Release the trigger and the power is shut off. This maximises battery life but involves exercising your index finger so not everyone likes it. But what do you notice about the Dyson V12 Detect Slim (ETBC, dyson.co.uk) above? That's right: it has a big red button on it like you'd see on a seaside arcade game. Whisper it, but Dyson is finally embracing the on/ off switch.

This isn't quite a first - the Dyson Micro also has this revolutionary new feature. However, that was a very small vac with a lack of features, with a very small on/off button. The V12 Detect Slim, by contrast, has all of the features, and a very large on/off button.
