Those who have an above ground pool use robotic skimmers or automatic skimmers that hung from the pool’s sides. Pool owners may have one or more skimmers depend on the size of the pool.

Pool skimmers are planned to suck water from the surface through the pool’s filtration system. The skimmers take away contaminants, water, and rubble such as debris, leaves, sunscreen, and hair from the pool before they go down to the bottom. Most of the pool’s skimmers are drawn about the top 1/8 inch into the water. So that skimmers can remove debris and chemicals properly from the pool.

When you run the pool pump, the Skimmer pulls the water and floating debris from the pool surface through a pivoting flap, which is called a weir, after passing the debris through the weir, and collected through the skimmer basket. The circulation system continues this process until the pool pump is turned off. After turning off the pool pump, the pivoting flap proceeds to its original position, where it avoids the debris from coming back into the pool. At this point, the skimmer baskets control the debris from the pool surface and routinely make sure free water flow and maximum filtering ability.
