I bought this for one reason. The condo floors were very dirty when I moved in and I wanted to walk without getting dirty feet.  It took 4-5 passes changing out the pads 3 times per pass. The biggest complaint from previous reviews is that it falls apart in time.  The machine seems sturdy but time will tell.   It is easy to use.  I have to fill the tank 2-3 times for 1300sf and need to run the pads through the wash twice.   It was not a miracle machine but I am happy with the purchase and feel that it is worth the money if it doesn’t fall apart in a few years.
