In 1996, Electrolux introduced the first “Robotic Vacuum Cleaner”, the Electrolux Trilobite.[3] It worked well but had frequent problems with colliding with objects and stopping short of walls and other objects, as well as leaving small areas not cleaned.[3] As a result, it failed in the market and was discontinued.[3] In 1997, one of Electrolux's first versions of the Trilobite vacuum was featured on the BBC's science program, Tomorrow's World.[4]
