Abstract: A robotic cleaner may include a main body, one or more drive wheels coupled to the main body, one or more surface type sensors coupled to the main body, the one or more surface type sensors being configured to receive robotic motor sound reflected from a surface to be cleaned, the robotic motor sound being generated by one or more motors of the robotic cleaner, and a controller configured to determine a surface type based, at least in part, on the reflected robotic motor sound.
