A robotic vacuum cleaner called ‘Limbo‘ was created by industrial designer Elliot Cohen as a concept project for the 25th anniversary of Casabella. Unveiled at the 2013 International Housewares Show in Chicago, it was designed “to inspire and push the limits of design and engineering for the future.”
Limbo’s adjustable wheels can be expanded, contracted, or lowered to give it fast ground coverage, help it clean close to walls, and climb up stairs. The robotic floor cleaner also powers itself through the bacteria it consumes.
This process, known as microbial electrolysis, enables the vacuum cleaner to recharge itself as it picks up bacteria off the floor. So as long as your floor is dirty, it can continue to work without the need for a charging station.
