Abstract

A vacuum cleaner module including a vacuum blower head and a support assembly for positioning in an opening defined between a movable window and a corresponding window sill of a building. The support assembly mounts the blower head outside the building adjacent to the movable window and the window sill when the support assembly is positioned in the opening. Some embodiments of the vacuum cleaner further include a cyclone separator and silencer which communicates with the fan outlet of the vacuum blower head for reducing emission of dust and noise from the vacuum blower head. Other embodiments of the vacuum cleaner module further include a muffler for attenuating suction noise generated by the vacuum blower head.
