The Dyson Airblade taps’ unique design allows the user to wash and dry their hands by triggering an infra red sensor underneath the tap.

The machine consists of a unit placed underneath the sink containing a motor, an air filter and sound-silencing equipment; a pipe that carriers the water, electrics and air to the tap; and a stainless steel head unit from which the water flows and unheated air jets out at 430mph (692 km/h).

Infrared sensors detect where the user’s hands are – if placed under the tap’s centre water comes out, if under its sides the air nozzles are triggered.

The firm’s founder, Sir James Dyson, said that the device offered long-term savings over hot air dryers and towels.
