This machine is a waste of money. It will never replace a mop.It is only suitable for lightly soiled floors.It won't touch dirty, scuffed and dusty floors.It's cleaner solution is also very expensive, and a small 150 sq. feet kitchen & breakfast area, needs three refills.Its brushing action is pathetic and weak. Its wet pick-up is a joke.Also, it's made very cheaply, with the plastic parts looking as if they came from Toys-R-Us.Buy a powerful steamer.Pass this one by.
