I had a hard time setting up a map for this robot vacuum because it was always hitting the walls.

Oh yes. A robot vacuum cleaner is a useful purchase only for those people who have a one-story house without thresholds at the entrance to each room. If I buy a robot vacuum cleaner, it will only stay in one room because it can't move out. I have a pretty old house. It's like 50 years old, so that doesn't work for me. But I have a great Dyson vacuum cleaner. It has a good battery. I use it once a week and charge it once every two or three weeks. So that kind of thing is more convenient than a robot. By the way, I can attach any of the Best vacuum cleaner attachments I buy to it. I like to experiment, so I buy different brushes for that.
