Just adding to previous reviews. The robot works well, if conditions are created for this. I did it this way, initially I put the base in the middle of the room next to a narrow passage between the wall and the bed, and if the robot left to get out there, then it stayed there because the base makes it turn around without driving up a significant distance. It turned out that he was locked in one half of the room, since he couldn’t crawl under the bed (height of the robot is 8cm) and the base doesn’t allow passage. It is better to put the base in the corner of the apartment, then it will go everywhere. I also got tangled up on the cat scratching post, now we are removing it. And so I advise, the hard worker is excellent!
