Disclosed are a cleaning device for a ceiling-mounted air conditioner and a cleaning robot for a ceiling-mounted air conditioner to which the cleaning device is applied, wherein the cleaning device for a ceiling-mounted air conditioner comprises: a fixed block that is able to rotate about an axis thereof; a guide frame provided on the fixed block, wherein the guide frame is provided to move in the longitudinal direction of the fixed block; a distance sensor provided on the tip end of the guide frame to sense a distance relative to a heat exchanger for each rotation section while rotating 360 degrees together with the guide frame; a cleaning nozzle provided on the tip end of the guide frame to spray cleaning water toward the heat exchanger; a cleaning head that comprises a control unit that computes a correction value for correcting the distance between the cleaning nozzle and the heat exchanger to be an optimal distance on the basis of the distance measurement value sensed by the distance sensor and controls the distance by which the guide frame moves forwards and rearwards according to the correction value; and a driving means that moves the cleaning head forwards, rearwards, upwards, and downwards and rotates the cleaning head. |
