The Improved Ecto Vac [1] is an invention of Professor Dweeb that improves upon its predecessor, the Ecto Vac.


After the Ecto Vac failed to capture Slimer in its maiden trial, Professor Dweeb upgraded the device so it fitted on a suit mounted on tank treads. Dweeb took the Improved Ecto Vac into Central Park but ended up grabbing a gorilla instead of Slimer. After the gorilla screamed at Dweeb, the Improved Ecto Vac took off in Dweeb's Van.
