(54) Vacuum cleaner


(57) An electric blower employed in a vacuum cleaner for creating a suction air stream in order to collect dust particles reduces level of noise heard by the operator, by reducing flow resistance in the vacuum cleaner, facilitated by the limiting the volume thereof to about 20% of that of the main body of the vacuum cleaner. Moreover, by limiting the volume of the blower, dust storage capacity can be expanded without having to significantly change the dimensions of the main body used by a convention vacuum cleaner. Thus providing greater comfort and convenience to the operator.
