Abstract: A robot cleaner according to an embodiment of the present invention comprises: a travelling part for moving a body; a memory for storing travel state information of the traveling part, which is recorded while a cleaning operation is performed on the basis of a first map; and a control part for discriminately detecting a first area and a second area divided from a plurality of cleaning areas corresponding to the first map, on the basis of the stored travel state information. Moreover, the control part may generate a second map by removing one of the first area and the second area from the first map, and then control the travelling part to perform a cleaning operation in a changed cleaning mode on the basis of the generated second map.

Abstract: A scroll compressor includes a motor portion fixed in an inner space of a casing, a compression portion fixed to the inner space of the casing at one side of the motor portion in an axial direction, a rotation shaft to transmit a driving force from the motor portion to the compression portion, and a flow path guide provided in a discharge space between the motor portion and the compression portion and provided with a guide outlet communicating with the discharge space and opened in a direction toward the rotation shaft. Therefore, most of refrigerant discharged to the discharge space through the flow path guide is moved toward an air gap to enhance an oil separation effect, and thus a normal operation point of the air conditioner can be accelerated.
