I doubt it was turned on
It was very obvious that had they gone a bit slower with the DC-25 it would have easily chomped the Windtunnel Air or leveled the playing field as shown by how quickly the guy brought the Dyson back to hastily turn it off on the carpet as it actually got almost everything that could have been gotten up except for the stuff in the front that didn't get sucked up due to the Dysons carpet-suction-sealing design.
This is why the Dyson snow-plows. A Kirby will snow plow just as bad but it's one of the best machines in the world for pulling out deep embedded dirt. As is the Dyson I'd wager.
Not so sure on the Air...
