PURPOSE: To allow running in a narrow place upon collapsing of a cleaning tool, enable running in an area with obstacles as hindering passage of any vehicle, and clean a ceiling, wall, racks, etc., by constructing the cleaning tool so as to be mobile freely with the aid of a specific arm.

CONSTITUTION: An arm 7 with multiple degrees of freedom equipped at the tip with a cleaning tool and internally with an obstacle sensor 8 is mounted on a rotary table furnished in the upper part of the body 6, which should constitute a cleaning part. The periphery of the tip of this arm 7 constitutes a mobile tip as protruding from the cleaning tool, and this is butted to the floor surface for running to enable lifting the body 6. At the tip of the arm 7, a hot blower is provided to send the heat generated in the body device as a hot wind to an object to be cleaned via a pipe. Running is made in conformity to the instruction given by a controller 5 in the body device, and the cleaning tool makes necessary movement with the aid of the arm. Thus any narrow place, ceiling, wall, etc., which does not admit the body device running can be cleaned with the cleaning tool.
