Robot vacuum's app map is inaccurate or the robot seems to forget room layout between runs.

Safety first: Ensure the robot has adequate battery charge.

• Update firmware: Use the Bissell app to check for and install any updates.
• Allow full runs: Let the robot complete full cleaning cycles without being moved or stopped prematurely.
• Reset map: If the app allows, delete the existing map and let the robot remap the area from scratch.
• If mapping remains inconsistent: The navigation or main control board may have a hardware fault. Professional diagnosis of the navigation sensor board and main PCB is recommended.
