I love, love love my little Sally. I have dark Laminate flooring that show every speck of anything. Now I'm not sweeping and vacuuming all day. When I get up in the morning, I make my coffee, turn Sally loose in the house while I sit on the porch drinking coffee. Sometimes I have to turn her off and move her to a specific spot, but not a problem. I had a problem getting her moving at first, so I opened the battery compartment and changed out the batteries with Duracell. No more problems. Our bedrooms have Berber carpet and that is not a problem for her. Once again, I love her, and she has made life a little easier for me
