Port maintenance
Keep the port and the workstation area as clean as possible. The insides of the Ports should be vacuumed regularly, and at least once a year. Use a cloth to clean the Port's control panel and furniture.
Grid maintenance
Top tracks (where the robots are running) must be kept clean to avoid system stops. Dust and dirt should be vacuumed yearly. For very dirty areas, use a cloth to clean the tracks.
Robot maintenance
Use a cloth to remove the dust from the robot cover sheets, and, preferably, some compressed air to clean the track sensors. There is one sensor on each side of the robot, plus two at the front under the gripper. All track sensors are right next to the wheels.
