The Poltergust 3000 is a vacuum invented by Professor E. Gadd to catch ghosts. It first debuted in Luigi’s Mansion, where Luigi used it as his main weapon. It is the first model in the Poltergust line of devices, named after the terms “poltergeist,” a ghost who makes itself known through things such as noises, and “gust,” referring to wind. The “3000” part of the Poltergust 3000’s name is likely a nod to the “thousand” numbers after mad scientists’ inventions in typical science fiction movies. It is also a parody of the Proton Pack from the Ghostbusters franchise.
