ABSTRACT:
A vacuum cleaner includes a cleaner housing accommodating a motor-driven air blower and having a dust collection chamber defined in a front end thereof. An upper cover is detachably hinged at an end to the cleaner housing for closing an upper portion of the dust collection chamber and has a slanted surface inclined downwardly toward the front end. The upper cover has an inlet hole defined in the slanted surface for communication with the dust collection chamber when the upper portion of the dust collection chamber is closed by the upper cover. A connector pipe connected at one end to an intake hose has an opposite end rotatably coupled to the inlet hole. The connector pipe is bent at such an angle as to be directed substantially vertically when the hose is directed upwardly.
