IRobot Roomba 450 Mopping Robot - after 1 year

We have our IRobot Roomba 450 Mopping Robot for one year now. My wife really likes it. It helps her to manage the household. Together with our Neato vacuum robot, it helps to reduce the workload. As you can see, the robot has to do parts of a bigger room per cycle. Therefore we use the boundary limiters. Small IR emitting cases which create boundaries for the robot. So far we had no problems yet.
