摘要： A vacuum cleaner includes a cleaner body to which an intake hose is connectable, traveling members for enabling the traveling of the cleaner body, and an obstacle-escaping angularly-movable member angularly movably mounted on the cleaner body. A dust collector chamber is formed in a front portion of the cleaner body, and an electrically-operated fan is mounted in a rear portion of the cleaner body. The angularly-movable member is so arranged as to be angularly movable around an outer wall of the dust collector chamber. A portion of the angularly-movable member projects outwardly from the front face of the cleaner body and the front side portions of the cleaner body.

摘要： An electric cleaner is provided with a moving mechanism for avoiding or escaping an obstacle so as to turn and move a cleaner body when the cleaning body collides with the obstacle. According to the electric cleaner, even if the cleaner body is collided with the obstacle, it is easy to escape or avoid away from the obstacle to ensure a smooth travel of the cleaner body while preventing an overturn of the cleaner.
