K-733N is a Cleaning Bot NPC in Club Station Alpha. It travels around the station, constantly cleaning the floor. It has no missions or dialogue and serves only as a background character. Two other Cleaning Bots named K-733N work at Starbase 3001. They share the same role as the LEGO Club's K-733N; one sweeps inside the main chamber while the other cleans the area near the launchpad to the World Builder League. It is unclear if K-733N is meant to be a single character or perhaps the name of a series of Cleaning Bots.
