We are very satisfied with the vacuum robot. I was amazed by the floor plan of our house that he created. When I first started the vacuum, it went about halfway through our house before returning to the charging station. After it was fully charged, I selected "continue cleaning" and it went back where it left off, finishing the rest of the house. After the complete floor plan was created, I divided it into the rooms of our house. So that we can determine the areas that need cleaning. I divided the areas so that the purifier doesn't run out of power before returning to recharge. He always returned to the charging station. The kitchen was divided into two parts: the kitchen and the dining room so that the dining room chairs could be moved to the kitchen after cleaning. I walked around the house before using the vacuum to make sure all the cords were disconnected from the floor. There are several items on the floor that we move before cleaning if we want these areas to be fully cleaned. One decorative rug had long tassels, so we took it early. I chose the guest room as a test to see if he can find and clean it. He found a room, cleaned up, and returned to the charging station. I highly recommend this robot!
