Abstract
A vacuum cleaner having a filter assemblydisposed on grillbetween the bag chamberand motor chamber. Bag chamberhas a cover. Filter assemblyhas an upstanding wallprovided with a covering of resilient material, e.g. rubber. The coveris formed with a grillin a lower region. When the filter assembly is correctly installed, and the coveris in position, the resilient covering of the upstanding wallrests in sealing contact against the inner surface of the coverand over the grill. If the filter assemblyis absent, the grillprovides direct fluid communication between the bag chamberand the atmosphere. The cleaner will be ineffective in picking up dirt thereby alerting the user to the absence of the filter assembly.
