Abstract: A cleaner includes a cleaner main body including a suction motor and a handle, and a suction nozzle that is connected to the cleaner main body and includes a housing that defines an open portion at a lower portion, a rotary cleaning unit disposed inside the housing and exposed through the open portion of the housing, and a support member that is located below the housing and supports the housing and has an open interior and at least one sub-inlet that is defined at a front surface of the support member and configured to receive foreign substances. The cleaner includes a controller disposed at the cleaner main body and configured to determine a condition of the surface by driving an artificial intelligence engine, and open and close the at least one sub-inlet based on the condition of the surface to thereby adjust a suction force of the cleaner.

Abstract: Provided according to one embodiment of the present invention is a method for controlling a robot cleaner, comprising: a map data collection step of collecting first information collected by photographing a cleaning target area by means of a depth camera and second information collected by photographing the cleaning target area by means of an IR sensor; a depth data filtering step of removing, from the first information, information which is determined to be noise when detecting obstacles; and a data restoration step of, if there is a lost part of the information on the obstacles by comparing the second information with the information that is determined to be noise and removed in the depth data filtering step, restoring the lost part. According to the present embodiment, it is possible to obtain effective obstacle information by removing noise that is not removed despite filtering of the depth camera, so as to detect even thin obstacles.
