Abstract
The invention provides a resiliently mounted top cap for a cleaner bag that tends to urge a bag upwardly to tighten it. At the same time, the cap may be removed downwardly against its spring bias for shaking as a dirt loosening mechanism. The cap also includes an integral cord hook so that downward movement of it against its spring bias also provides a cord dump function.
