Abstract
In one embodiment, a system and method is provided for optimizing the total time taken for cleaning an area by a cleaning robot, which is the sum of the cleaning time and the time taken for the robot to re-charge its battery mid-cleaning when the area is too large to clean on a single charge. In one embodiment, the remaining area to be cleaned is determined, and the mid-cleaning re-charge time is reduced to the amount of charge needed to clean the remaining area, plus a buffer. Hence, a reduction in mid-cleaning charging time results in reduced total time taken to clean a given space.
