I have a 2,900 ft house, all wood flooring! I put one one one end of house and one on the other, use and extra cube and my house is dry or wet mopped automatically. At first I watch to see if the missed any areas or get stuck...but they did not! I now own 2 Braavas, and 1 Roomba 595. Looking to buy 1 more Roomba to complete the cleaning team! Much more free time to do the things I want and all my floors are nice and clean. You can purchase dry or wet mopping pads or attach swifter pads.
