PURPOSE: To achieve higher operability by facilitating the movement of a suction port body in a direction different from that of movement caused by the rotation of a wheel for running during a cleaning concerning the suction port body of an electric cleaner.

CONSTITUTION: The main body 1 in which a dust suction port 7 is formed on the underside 1a thereof is provided with a front wheel 18 and a rear wheel 15 projecting downward from the underside 1a thereof free to rotate, respectively. An auxiliary wheel 20 is provided at a position (at a front end part of the underside 1a) outward from the mounting positions of the front wheel 18 and the rear wheel 15 on the underside 1a thereof. A lower end of the external circumferential surface of the auxiliary wheel 20 is located at a position above the lower ends of the outer circumferential surfaces of the front wheel 18 and the rear wheel 15. The external surface of the main body 1 located between the front wheel 18 and the auxiliary wheel 20 is located inwardly from a straight line A connecting the lower end of the outer circumferential surface of the front wheel 18 and the lower end of the outer circumferential surface of the auxiliary wheel 20.
