The water nozzles are the parts that spray water on the floor when the robot is in mopping mode. They are located on the bottom of the water tank, which is attached to the robot. The water nozzles can get clogged or damaged over time, affecting the performance of the mopping function.
The printing took about under 5 minutes and the result was satisfactory. The water nozzles fit perfectly on the water tank and sprayed water evenly on the floor.
