The primary role of a pool skimmer is to skim floating debris off the surface of the water. This important function helps maintain the cleanliness of the pool by removing leaves, insects, and other debris before they can sink to the bottom and contribute to water quality issues. By capturing this debris at the surface, skimmers help prevent clogs in the filtration system and reduce the need for more extensive cleaning methods.

A pool skimmer works by utilizing a siphoning action that draws water from the surface into a dedicated skimmer box, trapping debris in a removable basket. This process not only aids in keeping the pool looking clean but also supports overall water circulation, which is essential for effective filtration and chemical distribution.

While circulation, monitoring chemical levels, and issues related to excess water are important components of pool maintenance, they are not the primary function of a skimmer. The skimmer's specific design and operation make it uniquely suited for addressing surface debris.
