Dyson Airblade Tap hand dryer explained- Official Dyson video
The Dyson Airblade Tap hand dryer washes and dries hands with no need to leave the sink. Infrared sensors pinpoint hand positions and release water from the tap stem. Once hands are wet and drying is requested, integrated circuitry computes the information and activates the latest Dyson digital motor, creating two high velocity sheets of air on the tap's branches. Unheated clean air is released to scrape water off hands leaving them dry in 14 seconds. http://airblade.dyson.com/default.aspx http://www.youtube.com/DysonUS https://www.facebook.com/dyson https://twitter.com/Dyson
DC59: Behind the scenes testing goes cordless - Official Dyson Video
Relentless invention sets Dyson apart, and nowhere does this hold more true than in our cordless line. Watch as Alex Knox, Director of Engineering at Dyson, takes our newest cordless machine, DC59, to task in Dyson's testing laboratory in Malmesbury, UK. Stacked up against the Electrolux Ergorapido, among others, in tests of suction power, fine dust pick-up, edge cleaning, filtration and versatility, DC59 comes out on top time and time again. DC59: Sucks up as much dust as a conventional vacuum.* Without the hassle of a cord. https://www.dyson.com/dc59 http://www.youtube.com/dysonus https://www.facebook.com/dyson https://twitter.com/Dyson #cutthecord *To prove this our engineers test for pick up performance across carpets (ASTM F608), hard floors (ASTM F2607) and hard floors with crevices (IEC 60312-1 5.2). To mimic actual use, they load machines with dust before testing (IEC 60312 -- 1 5.9).
