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.
