A:Answer Answering my own question. Turns out that the dust bin is only one of several parts that can get plugged or jammed with debris, or in this case dog hair. The roller bar, which comes out very easily for cleaning, is the primary culprit, with the dust filter assembly also due for frequent cleaning. The vacuum itself does work for about 2 hours on a charge, but cleaning is necessary, at least in our big house, several times during use. Runs well and does a fine job!
