A. 1. Ensure that the robot is placed in an open area during the initial mapping process to avoid obstacles. 2. If the map is incorrect, use the app to delete the existing map and run a new mapping cycle. 3. Make sure the robot's sensors are clean and unobstructed.

B. 1. After mapping, manually adjust the map in the app to correct any inaccuracies. Use the editing tools provided in the app to refine the layout.
