Cleaning the Robot
Depending on weather and soil conditions, caked-on mud can sometimes impede Tertill. Mud sticking to the treads of the wheels usually dislodges once conditions change. However, mud can sometime accumulate beside and under the wheels to such a degree that the wheels cannot turn freely. (See Unjamming the Wheels for more information)
You can use water from a garden hose to clear mud from the wheels and any other surface to which it sticks. We recommend not using a spray head for this purpose. Also, do not immerse the robot in water and do not spray with a pressure washer. Tertill is sealed against rain but is not intended for full immersion or a high pressure spray. Also, do not use any harsh chemicals to clean Tertill, as they may damage the robot.
