cleaning the first plurality of zones by the cleaning robot and traversing portions of the area between the first plurality of zones without cleaning;

indicating, by the user, a second plurality of zones to be cleaned on a second floor plan;

transferring data identifying the second plurality of zones to the cleaning robot;

determining, by the cleaning robot, a second optimum order of cleaning of the second plurality of zones, and a route to each of the second plurality of zones in the second optimum order;

receiving a user indication of a first cleaning schedule for the first plurality of zones, and a second cleaning schedule for the second plurality of zones;

transferring the first and second cleaning schedules to the cleaning robot;

determining, by the robot, at a start time indicated by the first cleaning schedule, whether the cleaning robot is currently located on the first floor plan corresponding to the first cleaning schedule; and

navigating through the first plurality of zones and cleaning the first plurality of zones if the cleaning robot determines it is currently located on the first floor plan.

12. A cleaning robot, comprising:

a robot housing;

a motor mounted in the housing for moving the cleaning robot;
