Mega Maid is the transformed version of Spaceball I. It is shaped like a woman with a vacuum cleaner. The vacuum can both suck air out of a planet's atmosphere, and blow it back into an atmosphere. It appears very powerful, since it can clean a mountain of snow, and pull a forest's trees straight out of the ground (and put everything back neatly if set in reverse).
Mega Maid exploded after Lone Starr tricked Dark Helmet into pushing the self-destruct button, and an attempt to cancel the order failed due to the cancellation button going out of order. The head and the vacuum handle crash-landed on the Planet of the Apes.
- Dark Helmet refers to the Spaceball in charge of the "metamorphosis" of Spaceball I into Mega Maid as "Kafka". This references Franz Kafka, the author of a book titled, The Metamorphosis.
- Mel Brooks previously referenced The Metamorphosis in The Producers, when Max Bialystock picked up a copy of the book while searching for a potentially awful play, and decided after only reading one sentence ("Gregor Samsa awoke one morning to discover that he had been transformed into a giant cockroach.") that it sounded "too good."
