At my house, e5 has been working for a long time. I don't understand the negativity here and don't share it. And if you remember that his price is quite democratic, so in general. It cleans the whole apartment well, I have a one-room apartment. Including carpet in the room and rug in the hallway. Completely independent, never gets confused, does not get stuck. The first time I just forgot to remove the wires, the wire sucked. But I noticed in time, pulled it out, everything is ok. I run it 3-4 times a week, this is enough to keep the floors clean all the time. I am definitely happy with this robot.
