Dustcup Guardsman
Seeing your vacuum made me think of the Guardsman I saw at the hotel we stayed in for a few days. The hotel Guardsman had a dustcup, and looked to be rather abused. I'd rather have a disposable bag like yours has over the dustcup.
The biggest problem with the hotel's Guardsman was user error. The housekeeper went through the motions of running the sweeper, but she rushed so much that the floors still looked dirty when she finished. There was a clump of hair outside my door during my entire 4-day stay.
