Please press the start button on the robot to continue. Vision error. (4101, 4102)


The laser that the robot uses for navigation experienced an error.  


Press the start button on the robot to clear the error message. If the error message returns please try the following steps:


  • Make sure that there is nothing stuck to the top of the Neato. Labels and Stickers can be enough to disrupt the Neato's laser.


  • Using a Q-Tip, make sure the robot's laser freely rotates. Rotate the laser 10 times to the left and 10 times to the right, making sure not to put the Q-tip in either of the holes.


  • Use short bursts of compressed air about 6" / 15cm away to clear debris from under the turret cap.


  • Try a soft reset by holding the START button until all the lights turn off. Then press the start button again. After the chime plays try the Neato and see if the error returns.


Some environmental  factors can cause this issue. Strong direct sunlight and reflective surfaces can make it difficult for the Neato to see. To rule this out please try run the Neato in another room / part of your home.
