An automatically moving floor processing device has a housing, at least one drive element that is driven by an electric motor and can rotate around a drive axle for movement purposes, and at least one contact element that moves ahead of the drive element in the direction of movement, which extends from a housing underside of the housing in the direction of a surface to be processed. In order to make it easier to overcome obstacles, a contact surface of the contact element pointing in the direction of movement and/or a connecting line that connects the contact surfaces of two contact elements be oriented nonparallel to the drive axle of the drive element, and be spaced apart from a contact surface of the drive element by a distance relative to the direction of movement that is less than one diameter of the drive element.本發明係有關於一種自行移動式地板處理設備(1)，具有殼體(8)、至少一個用於移動而由電動馬達驅動且可圍繞著驅動軸(2)旋轉的驅動元件(3)以及至少一個沿移動方向處於驅動元件(3)前方的貼靠元件(5、11、12)，該貼靠元件係自殼體(8)之殼體底側出發朝向待處理表面延伸。為了更簡單地越過障礙物(10)，本發明提出：貼靠元件(5、11、12)之朝向移動方向的貼靠面(13)及/或將兩個貼靠元件(5、11、12)之貼靠面(13)連接在一起的連接直線(7)係不平行於驅動元件(3)之驅動軸(2)，並且就移動方向而言係與驅動元件(3)之貼靠面間隔一段距離，而該距離係小於驅動元件(3)之直徑。
