Poltergust 3000

"That’s the vacuum cleaner I engineered to catch ghosts.... They can’t be caught using conventional means. So you’d better use this; it’s the only way to foil ’em! This is the only thing they fear!"

- Professor E. Gadd

The Poltergust 3000 is a vacuum created by Professor E. Gadd in Luigi's Mansion.

Features
The Poltergust is equipped with a vacuum and flashlight to hunt down ghosts, such as Boos. The user would stun a ghost with the flashlight, and suck away. It has the ability, with help from special Elemental Medals, to harness the elements of fire, ice, and water to fight certain ghosts.

It links up with E. Gadd's Portrificationizer to upload captured ghosts and turn them into portraits.

Other Appearances

 * The Poltergust appears in Mario Power Tennis as a Defensive Shot.
 * It makes a cameo in Super Smash Bros. Melee on the Vaccuum Luigi trophy's back.
 * It appears in Mario & Luigi: Superstar Saga, where it seems that it was succeeded by a more advanced model, the Super Poltergust 3001. Luigi was also shown to still own the original Poltergust, which he used in various cutscenes in the Starbeans Café.
 * Luigi later uses the Poltergust 3000 for some of his Audience antics in Paper Mario: The Thousand-Year Door.
 * The Porta-Gust, a Gaddget from Mario Party Advance and another of Gadd's inventions, appears to be a portable version of the Poltergust 3000 with Game Boy Advance-style controls.
 * Luigi's special kart in Mario Kart DS is the Poltergust 4000, an upgraded version of the Poltergust 3000. Like the Super Poltergust 3001, it is meant to be ridden on.
 * Wario and Waluigi's Coin Vacuum of Mario Party 7, which is also known to be built by Elvin Gadd, could very well be related to the Poltergust 3000.

Trophy Information from Super Smash Bros. Melee
''In a strange twist of fate, Luigi wins a huge mansion in a contest he didn't even enter, and the place turns out to be haunted! After meeting a weird professor named Elvin Gadd, Luigi enters the place armed with a flashlight and a ghost-sucking vacuum cleaner. Mario's trapped somewhere in there! Can Luigi save him?''

Trivia

 * The Poltergust 3000 is named after the terms "poltergeist", meaning "a ghost who makes itself known through things such as noises", and "gust", meaning "wind". The "3000" part of the name is probably present because of the "thousand" numbers after mad scientists' inventions in typical science fiction movies.
 * In Japan, the Poltergust 3000 is called the "Obakyuumu"; this name can be taken as a portmanteau of "obake" (a type of Japanese monster) and "vacuum" or, if pronounced as "o-vacuum", a use of the Japanese title "O", meaning "important".
