Noo-Noo (played by Mark Dean) is the Teletubbies' sentient automated blue vacuum cleaner, and then he turns orange. He cleans up after the Teletubbies ("Noo-Noo tidy up!"). It has been shown that Noo-Noo has extraordinarily large storage capacity. He also has the ability to spit out any contents, often things that it should not have consumed in the first place such as the Teletubbies' blankets, foods, or favorite things. Then he is called "Naughty Noo-Noo!"
