Query: They should be ashamed

The vacuum just throws the dirt at your feet. I can run over tissue paper and it will not even pick it up. I run over little peices of paper, tissue paper, and dust like 10 times and it won't pick it up. The suction works fine, its just that the roller doesn't push the dirt into the suction area. They should recall this vacuum.
