This is the first robot vacuum, and I'm happy with it. You can use this straightforward and practical application even if no one is home. The main goal of the initial cleaning is to thoroughly clean the apartment, lift the chairs, and clear the excess from the floor. After that, he will accurately map out the apartment and divide it into zones, which will ensure that there are no cleaning issues. They even threw it under the disassembled sofa before driving in, tidying up, and leaving without incident. I advise buying.
