<p>The present invention concerns a normal vacuum cleaner wherein one end of the rotational shaft of a motor in a suction chamber has mounted thereon a blower for causing solid matter on the outside of a body to flow via an inlet port into a dust chamber and for discharging air that has flowed in together with the solid matter at an emission port of the suction chamber, and either the body is provided with a means whereby the motor can change direction in the suction chamber or else the motor is capable of forwards and backwards rotation so that the blades of the blower can selectively rotate forwards and backwards such that the vacuum cleaner autonomously performs filter cleaning and at the same time the user is prevented from touching unpleasant matter with their hands such that filter cleaning and replacement are easier for the user than hitherto.</p> |
