Abstract: A robotic cleaning appliance includes a housing, surface treatment item, surface type detection sensor, and processor. The sensor emits sonic signals toward a surface being traversed and receives corresponding returned signals from the surface. The returned signals are used for surface type detection and include directly reflected primary returned signals and multi-path reflected secondary returned signals which return at a later time than the primary returned signals. The processor selects a window of time after transmission of a sonic signal such that the returned signals in the window comprise at least a portion of the secondary returned signals, wherein the window is related to round trip time-of-flight of the returned signals; processes the returned signals falling in the window to achieve a reflectivity metric; compares the reflectivity metric to a stored value; and based on the comparison, determines which surface type of a plurality of surface types has been detected.

Abstract: Provided is a robot cleaner that travels along a virtual traveling line connecting a start point to a predetermined target point in a straight line. The robot cleaner includes a body having formed therein a space for accommodating a battery, a water container, and a motor, and a pair of rotation plates that have coupled to lower sides thereof, mopping cloths facing a floor surface, and are rotatably disposed on a bottom surface of the body, in which when a shortest distance between the body and the traveling line is greater than or equal to a predetermined reference distance, rotation speeds of the pair of rotation plates are different from each other.
