Why Do They Clean In Silo?
Short Answer
People clean because the helmet shows them a fake green world, making them believe they need to wipe the camera so everyone inside can see the truth.
Cleaning Is A Ritual, Not Just A Practical Act
The person outside wipes the camera while everyone inside watches. This makes cleaning a public spectacle about obedience, fear, and death.
The Fake Image Motivates Cleaners
Cleaners see a beautiful world in their helmets. They believe cleaning will help people inside see what they are seeing, but the inside view remains bleak.
