The dirt is sucked in with air through a suction opening. Typically, a hose is attached to the opening and is directed to the areas to be cleaned. One or more attachments may be provided to use on the end of the hose to clean different types of surfaces.An objective of the present invention to increase the size of a vacuum cleaner exhaust vent, thereby decreasing the volume of the noise produced by the vacuum cleaner. This is accomplished by directing the exhaust from the blower toward the front end, where there is room to provide a larger vent, with the blow port being in the smaller area toward the rear end.
