The SpotMaster 6000 is a machine SpongeBob used to clean off a hard spot off a plate in the episode: The Krusty Plate. It shoots a laser that has a combination of soap and water. The machine exploded shortly after SpongeBob invented it. The fact that it is dangerous to cross the beams is a reference to "Ghostbusters".
