Abstract
Disclosed herein are navigational systems for automated robotic floor cleaners. RFID passive tags are positioned at specified areas of a floor to be treated so as to increase or decrease dwell time of the cleaning device adjacent the tags. An RFID interrogator on the robot learns from each tag its nature, and based thereon instructs the device to change the dwell time over specified areas. This permits areas of a carpet or other surface requiring extra or less treatment to be cleaned in an optimal manner.
