<p>A vacuum cleaner includes a cleaner body (1) to which an intake hose (11) is connectable, a traveling member for enabling the traveling of the cleaner body (1), and an obstacle-avoiding angularly-movable member (710, 800, 801, 900) angularly movably mounted on the cleaner body (1). A dust collector chamber (5) is formed in a front portion of the cleaner body (1), and an electrically-operated fan (32) is mounted in a rear portion of the cleaner body (1). The angularly-movable member (710, 800, 801, 900) is so arranged as to form part of the traveling member and has casters (55, 55a) mounted on a lower surface thereof. The angularly movable member is mounted in a shaft (720) on a front lower surface of the cleaner body (1) so as to be angularly movable around the shaft (720). <IMAGE></p> |
