PROBLEM TO BE SOLVED: To solve the problem that a spring switch for safety damages a floor with a prong of the switch during self-propelling and that the spring switch is operated and movement or rotation of a brush is stopped on a self-propelled equipment when propelling over a step of a carpet or the like. SOLUTION: The self-propelled equipment is provided with a control means 6, a moving means 2a, 2b which propel and transport a main body 1, a step detecting means 4a, 4b which detect a step in front of or behind the main body 1, and a contact detecting means 7a, 7b which detect contact with an obstruction in front of or behind the main body 1; and the control means 6 conducts rotation/stop of a rotation part of the moving means 2a, 2b based on the content of detection by the step detecting means 4a, 4b or the contact detecting means 7a, 7b. Thus, it is safe even if the main body is lifted or turned over during the self-propelling, and besides, it can propel over the step such as a carpet, and does not damage the floor.
