They are the grids placed outside the channel in order to remove the particles in the inlet water. Since the sieve gap is quite small, it provides an advanced level of sieving. During the water inlet, the particles cling to the surface of the grid and removal is ensured by filtering the clean water through the grid pores. Generally, a mechanical cleaner is not needed for grill cleaning, the energy released during the flow of water is used for the cleaning process.
