Chimney Sweep is a recurring endurance challenge on Survivor. It debuted in Survivor: Fiji and later re-appeared in Survivor: Tocantins, Survivor: Heroes vs. Villains, Survivor: Redemption Island, and Survivor: Edge of Extinction.
The castaways would brace themselves with their arms between two walls while standing barefoot on two foot pegs. Every 15 minutes, the castaways would move down to smaller foot pegs. When the castaways reached the third set of foot pegs, they would try to remain on them as long as they could. The last castaway to remain on their pegs would win.
Yau-Man Chan was the first contestant to win this challenge when it appeared as the first individual Immunity Challenge in episode 10 "It's a Turtle?!" of Survivor: Fiji. After more than one hour, Yau-Man became the last man standing by outlasting Boo Bernis, winning individual immunity.
The Villains tribe won a feast at an Outback steakhouse after winning this challenge over the Heroes tribe when it was set up as a head-to-head tribal Reward Challenge in Survivor: Heroes vs. Villains.
When it reappeared in Survivor: Edge of Extinction, the challenge came down to Gavin Whitson and Lauren O'Connell after multiple successive dropouts. Over 50 minutes into the challenge, Lauren dropped, leaving Gavin as the winner of the challenge.
