<p>A floor cleaning machine having a passive mapping system for determining position information associated with a plurality of RFID tags dispersed within a floor field during a floor cleaning process. The passive mapping system defines a floor map based on position information collected from the plurality of RFID tags. The floor map may be communicated to a remote map server and be utilized by a second floor cleaning machine during a different floor cleaning process. The mapping system can periodically update the floor map based on information collected during subsequent floor cleaning processes. The information may include RFID tag movement or replacement. In one embodiment, a remote mapping system communicates with a floor cleaning machine via wireless communication.</p>
