We are aiming to sweep the high place such as buddha and the restricted area such as solar panels using down airflow induced by a drone. Our target of this study is to sweep the dust on the cardboard robot with the height of 1.3m. JIS standard dust was used and distributed on the cardboard robot in the sweeping experiment. In the case of the shear sweep method with the bamboo leaves or silky duster, the drone positioning was difficult and the sweeping rate was bad. In order to improve the sweeping rate, the 45-degree inclined flow control plate was set under the drone. As the result, the dust on the cardboard robot was swept away at the rate of 100%. The drone with the 45-degree inclined flow control plate was swept away using not only down airflow but also side airflow.
