It has its positives- the navigation to map the room areas was intuitive and accurate. It was a time saver to be able to run while I wasn’t home. However I found that it didn’t do a great job getting dust and dirt along walls and corners. When it docks back into the station and empties into the bin it’s SO LOUD. We have a floor plan with different levels and trying to map for our upstairs was less intuitive and a bit frustrating.
