Hello, I gave the same problem.
T’habite you
Hello @Noura,
Welcome to RobotShop community.
We are sorry to hear that you are having trouble with your Litter-Robot.
Please provide us with your order number or a copy of the invoice.
Are you hearing any noises from the robot when it stops in the middle of the cycle?
Please remove the globe and check the black gear connected to the motor. When you press on the black gear with your finger, does it seem loose or free‐spinning? If so, please follow the instructions for tightening the set screw, here:

When replacing the globe onto the base, make certain that the track around the outside of the globe is properly aligned into the groove on the base.
Awaiting your reply.
Sincerely,
