Swept Away is an obstacle, used as the second obstacle in the Qualifier in Season 5, Episodes 13 and 19.
It is a sweeper bar placed on a rising pedestal that spins counterclockwise to take out contestants. When idle, the sweeper bar is placed at chest height, but if they jump, the bar would raise up and still hit them (similar to those used on the Ski Lift). Instead, in order to beat the obstacle, they had to duck underneath to get past it, and they aren’t penalized for doing so.
