ABSTRACT:
An electric cleaner incorporates an effective noise suppression arrangement for minimizing the noise generated by the exhaust from the electric air blower. The present invention provides an electric cleaner comprising an air rectifying duct installed on its external surfaces so that the exhaust from the electric air blower can smoothly and quietly pass through it, while the noise emitted by the exhaust can be significantly minimized throughout the vacuum cleaning operation even when using a compact cleaner.
