Every student's dream, The Noo-Noo is a sentient vacuum cleaner that cleans up the Tubbytronic Superdome, home of the Teletubbies.
Noo-Noo is a blue cylinder vacuum cleaner with eyes, a 'trunk' with the furry circular vacuum attachment at the end, and occasionally a flashing orange light.
A typical day for Noo-Noo might involve cleaning up spilt Tubby Custard and left-over (or unguarded) Tubby Toast before running around the Superdome's inside central column chasing the Teletubbies.
Technically Noo-Noo appears to be remote controlled (though the trunk is clearly guided with strings).
