Abstract
A vacuum-cleaner suction tool includes a sucking portion for sucking up dust on a surface to be cleaned, a joint portion having one end connected to the upper side of the sucking portion and the other end provided with a connection pipe, and an agitator disposed within the sucking portion for scraping dust off the surface. The opening, the joint portion, and the connection pipe each have a channel portion allowing sucked-up dust to pass therethrough. The joint portion is configured to be turnable, relative to the sucking portion, in a horizontal direction substantially parallel to the surface to be cleaned to such an extent that the longitudinal central axis of the sucking portion becomes substantially parallel to the longitudinal central axis of the connection pipe, whereby the forward end of the sucking portion, from left to right, can be brought into close contact with wall surfaces so that dust liable to collect in corners can be fully sucked up.
