It's good. We like it. It does as advertised. We like how it's just water, and we feel the floors are clean and sanitary. Not great around the perimeter, we feel we need to clean the corners, especially near the toe kick under the base cabinets. We have polished tile floor in our kitchen & bath. It leaves it streaky, doesn't look grea when it dries. My wife feels like she needs to broom that floor specifically, prior to running this device. Overall, we like it and we're going to keep it. We don't think it's suitable for the desired appearance on a polished tile floor.
