Abstract
A control system for a robotic floor cleaning machine configured to perform a cleaning operation along a cleaning path can comprise a controller, and a plurality of sensors. The controller can be configured to control autonomous movement of the robotic floor cleaning machine along the cleaning path and autonomous performance of the cleaning operation. The plurality of sensors can be configured to sense a location of the robotic floor cleaning machine relative to surroundings of the robotic floor cleaning machine. At least two sensors from the plurality of sensors are configured to locate the robotic floor cleaning machine in overlapping areas of the surroundings.
