Abstract
A cleaning machine includes a frame having wheels, a suction blower having an air inlet and an air outlet and mounted on the frame, an intake opening communicating with the air inlet of the suction blower for sucking dirt containing relatively large dirt such as fallen leaves and relatively small dirt such as dust together with air by the sucking force generated by the suction blower, a dirt separator communicating with the air outlet of the suction blower by means of a duct for separating the dirt from the air blown out from the suction blower, and a dirt receptable for collecting the relatively large dirt separated by the dirt separator, and the dirt receptacle detachably attached under the main separator. The dirt separator includes a main separator for separating the relatively large dirt in the air from the suction blower and a subseparator for separating the relatively small dust from the air having passed through the main separator, and the subseparator comprises a plurality of centrifugal dust separators for separating the relatively small dirt from the air passing therethrough by the assistance of centrifugal force.
