World class inventor and creator of the bagless vacuum cleaner, Sir James Dyson, has unveiled his latest household invention – the Dyson Air Multiplier.

It works by drawing in air from its surroundings and forces it out at up to 22mph through a 1.3mm slit creating a smoother flow than traditional fans.

Little fingers may be protected but the wallet will not. At £199 there may not be too many fans of this fan.
