DYSON PENCILVAC

That's a funny-looking pencil. You'd certainly struggle to write a shopping list with it, and you'd need to be an elephant to tuck it behind your ear, but the cordless PencilVac is still very fittingly named.

Dyson reckons it's the slimmest vacuum cleaner in the world, and with a handle that's just 38mm in diameter - similar to a can of deodorant - it makes Henry the Hoover look like he's been sneaking extra dust dinners while nobody's looking. At just 1.8kg it weighs about the same as nine hamsters, but it'll make less of a mess when you let it loose in your house.
