I can't believe I love this little mopping robot, as much as I do. I kept thinking there is nothing that can clean a floor better than Scooba. But Braava really does clean rather well. I also like the fact that there are no parts to replace. The gps works beautifully and my floors dry almost immediately. If my floor is extra dirty, then I run Braava twice. No hardship there. Braava cleans up to our thresholds that divide the rooms, and does not go over them, which eliminates the need to set up Lighthouses. It's not a problem for me to vacuum before using Braava, because I vacuumed before using Scooba, as well. Braava is half the price of Scooba and is ever so quiet. What a 'Treat' for us, who hate washing floors.
