Edge and cliff sensors do not understand tassels and mapping drift means a no go box that looks perfect today can miss by a few centimeters tomorrow. You actually can cut drift by always starting the job from the dock in the same spot and giving it a minute to localize before it moves. 🧭 Keep the dock square to a wall and free of nearby shiny surfaces so the lidar or camera has consistent first sights. 📡 Then draw the forbidden zone larger than the rug by a hand width on every side so even a sloppy run will not graze the corners and if you want a physical cue that does not damage anything, a low strip of black gaffer tape on the floor outside the fringe sometimes reads as a cliff to the sensors and the bot backs away. 👍 Test a small piece first and pull it the same day to avoid residue. ⚠️

Two things woke mine up at night... Tiny insects and tiny drafts. Closets are spider heaven and a little web across the PIR lens will trip it now and then. I popped the light off blew the lens out with canned air, wiped it, and vacuumed the upper corners of the closet. Tiny spider inside the Fresnel. Gone and no more random pings. If that is not it aim the sensor downward so it sees the floor instead of the door gap and clothes. Opaque tape works to narrow the view. A skinny crescent along one edge is enough. Diffuser tape will not help since PIR sees heat not brightness.
