The Poltergust 3000 is a vacuum invented by Professor Elvin 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.
The Poltergust 3000 is a vacuum used by Luigi to hunt down ghosts in Luigi's Mansion. To suck up ghosts, Luigi first has to find their weakness (which usually involves his flashlight in some way) and exploit it. Once the ghost is open, Luigi needs to bring it health down to 0 before it can be sucked into the Poltergust and defeated. By sucking up certain ghosts (which can be found after collecting specific Elemental Medals), the Poltergust gains the ability to harness the elements of fire, ice, and water to fight certain ghosts and solve puzzles.
In the PAL version of Luigi's Mansion, the Poltergust 3000 has wheels, which allow the user to ride it. Luigi can perform this technique in the Boolossus battle, but it is not used elsewhere in the game.
Other game appearances
Mario Power Tennis
The Poltergust appears in Mario Power Tennis and Mario Tennis: Power Tour as a Defensive Power Shot known as the Poltergust Return. Like other Defensive Power Shots, its purpose is to hit the ball when it is out if range. Its offensive counterpart is the Squeaky Mallet.
Mario & Luigi: Superstar Saga
Paper Mario: The Thousand-Year Door
Mario Sports Mix
The Poltergust 3000 appears in Luigi's Special Attacks in Mario Sports Mix. As there are four different sports in said game, its use varies slightly between each sport. However, each sport has him doing the same thing: Luigi sucks in the ball or puck, then he expels air from the Poltergust at his opponents to cause them to trip. After that, he either shoots the ball toward the goal (in basketball and hockey), toward the open ground (in volleyball), or at the opponents (in dodgeball).
Super Smash Bros. series
The Poltergust 3000 makes a cameo in Super Smash Bros. Melee on the Vacuum Luigi trophy's back, and it has a trophy of its own in Super Smash Bros. Brawl. It does not reappear at all in Super Smash Bros. for Nintendo 3DS / Wii U in favor of its newer model, the Poltergust 5000 (which appears as Luigi's new Final Smash, replacing the Negative Zone from Super Smash Bros. Brawl.
Throughout the Mario series, various upgrades to the Poltergust 3000 have appeared. These include:
