An upright vacuum cleaner having a motor housing, a handle pivotally attached to the housing, and a flexible dirt-receiving bag extending between the housing and the handle is disclosed. A top cover assembly is provided for supporting the top of the bag, and includes a rectangular cup-shaped cover having top, side, and end faces enveloping a portion of the top of the bag. An attaching assembly is provided for attaching the cover to the handle and to the top of the bag within the cover. The attaching assembly includes a wire hanger extending through the top face of the cover and then extending from a location adjacent one end of the cover toward the other end of the cover. The attaching assembly further includes a clamping web fixed to the underside of the top face. Downwardly and inwardly extending ends of the web enter pleats at the sides of the bag to removably hold the bag in place within the cover.
