Electrolux Trilobite

[9] The Trilobite contains a vacuum cleaner and a removable roller brush capable of working on deep-pile carpet.

It has the ability to map rooms and avoid obstacles by using ultrasonic sensors and Mark 2 model also had a infrared.

It recharges itself on a charging base, which it automatically finds when has completed its cleaning task or its power runs low.

Because the Trilobite stops a short distance from walls and other objects, it leaves small areas that are not fully cleaned.

Magnetic strips are used to block off areas that the Trilobite should not enter, and infrared sensors (on the Mark 2 model) protect it from falling down stairs or off ledges.
