At first, the robot vacuum was easy to set up and use. I liked the style and the convenience of the remote control. It's very easy to start and the cleaner returns to the charger when it's done. However, I will have to keep an eye on the vacuum cleaner when I use it because if I leave it alone, it will miss most of the apartment. If it hits a furniture leg, the area around the leg will not be cleared. Then I have to vacuum again with a normal vacuum cleaner because. There will still be dust and hair.
