A pool cover serves multiple purposes, but one of its primary functions is to reduce evaporation and prevent debris accumulation. By covering the pool when it is not in use, water loss through evaporation is minimized, which helps maintain the pool's water level and reduces the need for frequent refilling. This can also lead to lower chemical usage as the concentration of pool chemicals stabilizes when the water level is consistent.

In addition to preserving water, a pool cover also acts as a barrier to prevent leaves, dirt, and other debris from contaminating the pool water. This significantly reduces the time and effort required for cleaning and upkeep, allowing for a more enjoyable swimming experience and efficient maintenance.

While a pool cover may have other benefits, such as providing thermal insulation to help retain heat, its key roles focus on conservation of water and cleanliness of the pool area.
