A contract laborer who is "in" for 5 years, the NanoJanitor cleans the clean room in the nanosystems and material fabrication labs.

His nightly ritual is supervised via the school's Always Already Media Stream (A2MS).

Over several decades, he has worked his way up from sanitorial engineer to hazmat crew to NanoJanitor, and takes his responsibilities seriously, even as he longs to be home, outside, with his family.
