For me, the robot is good, there really is nothing to compare with, since this is my first robot vacuum cleaner, they chose it with my husband. But I watch how he cleans the apartment and I like it, it up dust and dirt well, sometimes it gets a little dull, it can get stuck, for example, colliding with a bag on the floor, but these are trifles, I try to remove things from the floor before cleaning, then everything is fine.
