Abstract
In an electric vacuum cleaner, in a suction air passage provided between a nozzle unit having a nozzle and an electric blower for producing a suction air flow, a separator for separating dust from the suction air flow is arranged. In the separator, a dust collection chamber for collecting the separated dust is provided. The separator is fitted with an exhaust tube having an outlet, fitted with a filter, formed in the peripheral surface thereof so that the suction air flow is exhausted out of the separator through the exhaust tube to the downstream side of the suction air passage. The separator is fitted with a cleaning member having a brush for cleaning the filter. When the cleaning member is moved with the brush keeping contact with the filter, the dust that has settled on the filter is raked off. The cleaning member is moved through manual operation, with a motor, or by the suction air flow.
