Has some pros The main thing that the robot helped me with was to clean the glass, where I myself could not reach. If you follow the instructions and clean the glass in several passes, it cleans well. I have a positive experience with the purchase Cons below: For a long time. Wash glass the old fashioned way much faster. One section cleans for 10 minutes, but 2-3 passes are needed. Divorces may remain. There is a solution - often change rags.
