How Does an Automatic Pool Cleaner Work?

There are three basic types of automatic pool cleaners, all designed to work with minimal human intervention. The first is called a suction-side pool cleaner, which actually uses its own pumping action for cleaning as well as locomotion. In this type, the pump that removes water, as well as debris, returns the same water, minus debris, to move the device through the pool. The second type of pool cleaner is called a pressure side, which actually pressurizes the water on the intake. This resulting pressure not only provides the suction, but also the locomotion of the device. Since this type of cleaner requires a booster pump to operate, it is the most expensive type of cleaner to use. The third type of pool cleaner is the electronic robotic, which differs from the previous two types in that it operates independently of the pool’s own pump. Instead, it uses a separate power supply to operate both the pump—which is self-contained—and the locomotion. The electronic robotic pool cleaners also differ from the previous two types in that they are also controlled by microchips which allow them to sense the terrain before them. The cleaner relies on these sensors to tell them what lies ahead of them and how they need to respond to them.
