Error 1029 means that the LiDAR Map your robot created does not match the map in the iRobot App.
Please review your map in the Roomba® Home App to ensure no changes have been made, and then try again.
If the error persists, please reboot the robot by holding down the power button on the robot for 10 seconds. Hold the button again for 3 seconds to turn it back on. Doing so should clear the error from the robot's memory. Try running Roomba® once again.
If these steps do not clear the error, please delete your map and create a new one with a mapping run or clean all missions.
If the error 1029 persists, even with a brand new map, please contact iRobot Customer Care.
