A self-driving cleaner includes a drive unit, a control circuit, a camera, a first sensor for detecting an object, and a second sensor for detecting a stuck state, and a third sensor for detecting a person. The control circuit is configured to (a) identify information about a target object which caused the stuck state, (b) receive information indicating whether the target object is to be cleaned, and (c) control the drive unit and a suction unit, when receiving information indicating that the target object is to be cleaned, to perform a first mode where a space excluding the target object is cleaned first and, thereafter, the target object is climbed if the person is not detected and perform a second mode where the target object is climbed first and, thereafter, the space excluding the target object is cleaned if the person is detected.
