Robots are also used to clean swimming pool surfaces. The swimming pool cleaning robot consists on a very simple concept. It has a drive motor a pump and a processor.
The pump is drawing the water from the bottom of the robot where the intake valves are located, through the filter and out to the top outlet of the cleaner. During that process debris and dust that are on the pool surfaces, being vacuumed into the pool robot filter section, and particles that are large enough stay inside the robots filter unit until cycle is done and disposal is being removed.
The drive motor is made to give the pool robot a directional movement but it does not determine the rout. The drive motor is driving the drive belts and the drive belts are driving the wheels or wheel tubes depending on the model.
The processor is made to determine the cycle time of the motors to a specific direction. The more advanced models have more advanced processors in which it remembers the pool's size and shape and determines the most efficient route to clean the entire pool.
