Automatic Swimming Pool Cleaners

Here is an overview of swimming pool automatic cleaners, the differences and how they work

Automatic Pool Cleaners fall into two basic categories. Suction cleaners and Electric Cleaners. Suction cleaners rely on the circulation pump of your pool to provide them with a through flow of water that sucks up the debris and makes them move around the floor of the pool. Electric cleaners work from a low voltage electricity supply and use their own power to move around the floor and the walls as well as creating a vacuum to suck up the debris. The big difference between the two (apart from the price) is that the suction cleaners send the debris to your sand filter but the electric cleaners keep the debris contained within their cleaning heads. Electric cleaners have the capability to suck up much finer debris than the suction cleaners.

All the cleaners work by randomly traversing the pool floor sucking up the debris. So they have to be left in the pool for long enough to get to every part of the pool floor. Cheaper cleaners seem to favour one end of the pool over the other end, the more advanced cleaners will cover the whole floor evenly.

Suction Swimming Pool Cleaners

The cheapest and simplest swimming pool cleaners are Suction models. The way they clean the pool is fundamentally the same for all the models, the big difference between the suction cleaners is how they move around the pool and how they don’t get stuck.

The Hayward Navigator is American made and has a very different design to the footpad cleaners. The Hayward Navigator and its smaller version the Magic Clean have a system of paddle wheels that are spun around by the incoming water flow and the paddle wheels attach to feet on the underside of the head unit. The feet flap around and make the head move around the pool in a spiral movement meant to prevent it getting stuck.

The Zodiac MX8 uses the incoming suction to drive the head but is much more advanced than the Navigator. It has tank tracks on the side that can go in forward or reverse and it is the only suction cleaner that can reliably clean the wall and steps of the swimming pool.

Electric Pool Cleaners

Electric Pool Cleaners usually work off a 24 volt supply. This means they are perfectly safe in the pool and even if one did go wrong a shock of 24 volts would be barely noticeable. They have a transformer that plugs in to the mains supply and a waterproof floating cable that supplies power to a cleaning head.

In the cleaning head there is a lot of clever electronics used to guide the head around the pool without getting stuck. An electric pool cleaner will have a motor that sucks the water from the underside in to the head. The pool water will pass through a filter which can be a bag or a fine paper cartridge and all the debris will collect within the head. At the end of the cleaning cycle you must clean out the bag or filters ready for the next time you use it. Electric cleaners use motor power to drive themselves around the pool. Some have wheels but the more advanced ones have tank tracks. When they meet the wall they start to climb it and the carrying handle which hitherto had been at right angles to the tracks will become parallel to the tracks. This movement of the handle relative to the tracks is detected by the cleaner so it knows it is on the wall and a secondary motor kicks in to keep it pinned to the wall. Once it reaches the water line the handle drops back slightly and this triggers the cleaner to scrub the water line for a while. When it has finished it goes in to reverse and back to cleaning the floor. The electronics within decide when it will clean the walls and when it will clean the floor.

Because the more advanced cleaners have paper filter cartridges they can pick up much finer debris than even your sand filter can collect leaving the floor of your pool spotless.

Further advancement in technology means that some cleaners can be remote controlled by the pool owner to drive it in to any area it may have missed.
