I am another one who figured out about a year ago that I can save time by using my vacuum cleaner to dust so I do both at the same time, but in top down order: wall pictures, ceiling fans, molding then furniture, TVs and finally the floor as I drag the vacuum cleaner from room to room.
I'm just curious for those stating their vacuum gets all the dust, is you vacuum bagless?? If it is than how do you empty it without the dust going back in the air???
