I have the Dyson 360 vis nav. I had been having issues with it getting stuck on my floor vents. The vents were flat and metal. Every time it would start to cross over it, it would stop and inch forwards and back. Sometimes it would free itself other times it wouldn’t. I tried no go zones but you can’t precisely place them. So I bought some lighter colored ones that are made of wood. They also have raised edges. I’ve tested the robot on low lift sensitivity and it is working perfectly. It no longer bugs out and tries to inch forwards and back. I don’t know if it thought the old ones were ledges or what. But I know many other people have experienced this issue and wanted to share what I’ve found.
