To get the floors clean, I have to first sweep, then vacuum, then mop. Yes, all three. The sweeping picks up the big parts of dirt. The vacuuming picks up the smaller particles of dirt. Then the mopping gets whatever dirt is leftover. I try to get the high traffic area daily, at least with sweeping and vacuuming, but I'm beginning to think it's a lost cause. Don't even get me started on all the dust that gets everywhere!
