Abstract: The present invention relates to a motor comprising: a motor housing for receiving a stator and a rotor therein; an outer housing detachably coupled to the outside of the motor housing; a first cooling path which is formed inside the outer housing and in which a first cooling fluid flows; a second cooling path which is formed inside the motor housing and in which a second cooling fluid flows to be capable of exchanging heat with the first cooling fluid; and a plurality of spray holes interconnected to one side of the first cooling path and formed to extend through the motor housing toward an inner space of the motor housing from the outer housing to spray the first cooling fluid into the inner space of the motor housing, and thus the present invention allows an oil path housing for oil-cooling to be easily attached to or detached from a water-cooling path housing.

Abstract: A robot cleaner includes a cleaner body, a suction unit, and a cyclone unit. The cyclone unit has a first suction opening and a second suction opening for sucking air, and a first cyclone and a second cyclone for passing air therethrough, the air having dust filtered therefrom by a centrifugal force. A first guiding member and a second guiding member extend upwardly from the suction unit toward the cyclone unit with an inclination angle, the first guiding member for connection between the suction unit and the first suction opening, and the second guiding member for connection between the suction unit and the second suction opening. A dust box communicated with a dust discharge opening is provided at a front side of the cyclone unit so as to collect dust filtered by the cyclone unit. The dust box is partially or wholly accommodated between the first and second guiding members.
