    Abstract: A robot cleaner includes a main body that autonomously travels, a suction nozzle configured to move up and down or swing with respect to the main body, and a support to support the suction nozzle. The robot cleaner may respond to a change in a height of a floor to improve travel performance and may respond better to obstacles. Even when a height difference of the floor is large, cleaning performance may be improved by maintaining contact and increasing a suction pressure of the suction nozzle.

    Abstract: A cleaner includes a cleaner body; a dust container which is accommodated in the cleaner body; a sensing module which detects information around the cleaner body and is mounted in the cleaner body rotatably about a rotating shaft that intersects a horizontal direction; and a driving module which rotates the sensing module in place relatively to the cleaner body.

    Inventor: Woo Hong Sangik Lee

    Abstract: The present invention relates to a robot cleaner. The robot cleaner comprises: a cleaner body equipped with a driving wheel; and a cleaning nozzle mounted inside a downwardly open opening portion in a lower portion of the cleaner body so as to be able to ascend and descend. The cleaning nozzle can be supported by a plurality of ascending/descending guides and a plurality of auxiliary ascending/descending guides so that the cleaning nozzle can ascend and descend relative to the cleaner body according to changes in the height of a cleaning surface on which the cleaner body travels. Accordingly, the cleaning to nozzle rises upon being pressed by a compressible floor such as a carpet, thus solving the problem of the cleaning nozzle catching on the cleaning surface. Therefore, travel performance can be improved, and the load on a brush driving part can be reduced.
