05.Pool cleaner types

There are three types of pool cleaner out in the market:

  • suction
  • pressure
  • robotic

Most pool cleaners you’ll come across are suction models — they’re the most visible in the market, cost less than other types and are easy to install. They’re all designed to clean hard pool surfaces such as concrete, pebble, acrylic and tiled.

Suction cleaners are usually fixed by a hose to the pool’s skimmer box, which filters the leaves, and are propelled by the force of water running from the leaf filter to the pool pump. The design of the cleaner’s head and surround (which ranges from futuristic to bug-like) is what makes or breaks the performance of a pool cleaner, but unfortunately you can’t tell how well it will work by looking at it.

The tested pool cleaners come in two main types, which both use suction to clean as well as to stick to the pool walls. One type works by stopping the flow of water and starting it again, making a pulsing action. This action can be provided by a diaphragm, ball or hammer movement in the head of the cleaner; these are called inertia-driven cleaners. The second type has gears that funnel water into a drive that propels the feet or wheels.

Pressure cleaners also work with the pool pump, using a combination of suction and jet action; while robotic cleaners, which are electric and self-propelled, function independently of the pool pump system.
