Input:
With the influx of bagless vacuum cleaners it has become increasingly difficult to find AA size replacement bags for our aging vacuum. Until the current sweeper gives up, we'll hang in there with it. I appreciate being able to purchase the bags online because while the vacuum models that use bags are becoming obsolete, dirt is not!
