Which type of pool skimmer operates automatically?

A robotic skimmer is an automated device designed specifically for maintaining pool cleanliness without the need for manual intervention. These skimmers operate by using sensors and advanced technology to navigate around the pool, collecting debris such as leaves, dirt, and other contaminants from the water's surface. By functioning independently, robotic skimmers save time and effort for pool owners, allowing them to enjoy a clean pool with minimal maintenance.

In comparison, manual skimmers require a human operator to physically use a net to scoop debris from the pool surface. Wall-mounted skimmers are typically stationary systems that rely on the pool’s circulation system to draw water through a skimmer basket, but they do not operate independently like a robotic skimmer. Floating skimmers also rely on the movement of the water surface and may require manual assistance or periodic attention to remain effective. Thus, the key characteristic that defines the robotic skimmer is its ability to operate automatically, which sets it apart from the other types mentioned.
