The Spot-Master 6000 is an invention made by SpongeBob that appears in the episode "The Krusty Plate."


It contains three different lasers. The first is a microwave-powered laser particle beam, the second is a laser-guided high-pressure water cannon, and the third are some pieces of steel wool that have a laser.

When turned on, the microwave-powered laser shoots out a green laser, the water cannon shoots out water, and the steel wool laser shoots out a yellow laser. The device also has the ability to cross the laser beams.

Role in episode

In order to remove a dirty spot on a plate, SpongeBob invents the Spot-Master 6000. Later, when he sets the machine on maximum power, the Krusty Krab explodes and the invention disintegrates.


  • The Spot-Master 6000 is similar a concept in the 1984 movie Ghostbusters, in which it is revealed that crossing the beam of their proton-pack lasers will end life as they know it.
