Electrolux Trilobite is the world’s first robotic, fully-automatic vacuum cleaner. It cleans hard floors and carpets without supervision at pre-set times, and can deal with stairs by the help of it’s sensors. Trilobite has the sensors of a bat; using sound to find it’s way around. Ultrasound at 60khz.

One of the greatest features of this vacuum cleaner is that it can recharge itself by finding it’s way back to the station and automatically docking itself on! After recharge, it resumes cleaning. This feature alone makes it first of it’s kind.
