I bought the S7 for my 3 stories house. It's amazing and smart robot cleaning machine. It's can saved a lot of time for cleaning. I have suggestion about the mopping. It's spray out the water about 3 inches wide in the center. Can it spray more water and wide area?
I have to pre moist mine in water it does need more spots on the mop to spray out water. This may be fixed on the s7 ultra
