In circular shaped, conical or flat-bottomed pools, the wastes that settle to the bottom are removed from the water by the scraping mechanism connected to the movable bridge that makes circular movements on the water.
It is designed in accordance with DIN 19569 and EN 12255.
The scraping mechanisms of rotating scrapers can be crawler or suction, and the bridge can be driven from the center or from the periphery.
Depending on the amount of bottom-surface waste and the pool structure, it can be half, extended or fully bridged.
They can be produced as epoxy-galvanized steel or stainless steel.
