it’s been 3days using this product and i am very satisfied with it functionally. automatically recognized objects and save the map of the living room also clean almost perfectly. it is very convinient to gather dust into the dustbag at the clean station that means i dont’t need to empty the dustbag every each time it cleans the livingroom. 
one thing i want for this product is that it can save multi maps so i can use it for different floors. other than that, it is perfect to use for homs.
