It is much easier to vaccum and then swiffer. The battery doesn't last that long. I have a small house, and I am lucky to get 2 rooms done. The plastic parts do not secure well and cause the machine to turn off. As for vacuuming and mopping at the same time, you have to stop 3-4 times per room to unclog the machine and empty it. I would characterize it as a colossal waste of money. Keep vacuuming and get a swiffer mop. Save yourself several hundred dollars and a lot of frustration and time.
