Abstract
A dust separation section is provided at a suction air passage between a suction opening of a vacuum cleaner main body and an intake opening of a motor fan to separate dust sucked from the suction opening with air and a dust collection section provided at the suction air passage for collecting the dust separated from the air from the dust separation section. Moreover, the dust separation section of the electric vacuum cleaner has a dust guiding space adapted to inflow the dust sucked from the suction opening from one end of the dust guiding space and for guiding the dust from an other end of the dust guiding space to the dust collection section, through a dust strike section, by an inertia force, and an air guiding air passage is provided to guide air from a midstream of the dust guiding space to the intake opening of the motor fan without passing through the dust collection section.
