Do you wipe down your counters prior to sweeping the floor?
Cleaning should always be done, Top - Down, unless you like a dirty house. When dusting, if you really want to vacuum the dust, it is best done several hours prior to vacuuming, because most of it will be floating in the air, and want be on the carpet immediately after dusting, unless you have big chunks of dust.
Edit: Keep this in mind if the argument is between you and your spouse. Dr Phil says, "you can be right, or, you can be happy." A lesson learned is that a good marriage may come at a small sacrifice of proper cleaning procedure.
