    Abstract: A vacuum cleaner bag cleaning system that provides a receptacle compartment having a removable top wall having a cylindrical cleaning member extending through it into the compartment for holding an inverted cloth vacuum bag. An exhaust fan motor unit also is positioned at the top wall and draws air through the cleaning member and through the cloth pores of the bag, thus forcing out entrapped particles of dirt and general debris caught in the bag and further drawing the air from the compartment and exhausting it to the atmosphere.
