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.

Abstract: A robot cleaner includes a cleaner body for forming appearance of the robot cleaner, a driving unit mounted to the cleaner body and configured to generate a suction force, a suction unit provided at the cleaner body and configured to suck dust-contained air by the driving unit, a first guiding member and a second guiding member communicated with the suction unit, respectively, and spaced from each other, and a cyclone unit configured to filter dust from air sucked through the suction unit using a centrifugal force. The cyclone unit has a first suction opening and a second suction opening communicated with the first guiding member and the second guiding member, respectively. The cyclone unit further has a first cyclone and a second cyclone configured to pass dust-filtered air therethrough.
