Miele RX2 works fine for us. It just arrived and I started using it straight away after the first charge. Our parquet floors with lots of animal hair are clean and I hardly participated. He knows our house very well. I moved items around when I first used them to give as much surface area as possible but left the mats in place. Almost everything collected. The battery life is excellent. It is quiet compared to other robot vacuums and our standard Miele vacuum cleaner. There are no problems with the transition to other rooms. I haven't dealt with the app yet. Very satisfied! I would buy it again. If you're looking for a great robot vacuum that's QUIET, can handle a lot of pet hair (think a few heavy-shedding dogs that live year-round), and has great battery life, then this is it for her. It's excellent at avoiding obstacles, but we don't have a particularly difficult environment to navigate.
