What is an example of a mechanical pool cleaner?

A robotic pool cleaner is considered a mechanical pool cleaner because it operates autonomously or semiautonomously, using programmed instructions to navigate the pool's surface and clean it effectively. These devices typically have their own power source and can maneuver around obstacles, climb walls, and access different areas of the pool without the need for manual intervention. They are designed to remove debris, dirt, and algae from the pool floor and walls, making them an efficient option for maintaining pool cleanliness.

In contrast, a manual vacuum requires the user to physically push it around the pool, and a skimmer net is primarily a hand-held tool for surface debris removal rather than a mechanically powered unit. A chlorinator, on the other hand, is a device used for adding chlorine to the pool water to maintain water quality but does not clean the surfaces of the pool. This distinction highlights why the robotic cleaner is the correct example of a mechanical pool cleaner.
