content: I have hard floor throughout the entire house both ceramic tile and Laminate wood. I got rid of carpet because it is filthier. I also have two dogs that bring dirt in and out between slight shedding. I have learned about this Unit, and gave it a try. Well, BIG DISAPPOINTMENT. First of all, the unit is too small. You have to go back'n force over and over between trash bag, refilling to machine between cleaning which gets old fast. Then, it does not clean as good. For 12 x 12 Ceramic tile, you would have to go over and over the area before you can move on. I found it MUCH easier and LESS expensive to just sweep or vacuum with a regular vacuum machine, and then use mop to clean the floor. It gives BETTER result in no time~!! DO not wast your time and money into cheap GADGET like this one, or Floor Mate, the worse. Do not get the lazy idea, just do it physically can actually save you a lot of trouble. I am taking it back.
