Abstract
A vacuum cleaner is provided that is adapted to detect and display and/or avoid obstacles. In such vacuum cleaners the driving wheels and/or castor wheels that determine the direction of travel may be actively controlled to achieve, at the point in time of obstacle touch or obstacle sensing, a resultant velocity away from obstacles in the path of the cleaning apparatus.
