Basically there are three different types of swimming pool cleaner any of these can be operated either manually i.e one switches the filtration system on manually at will. or automatically that is the switch is operated by a timer that is set to run the system for a period or periods of time over given period.

1 A very popular filtration systems in use today is the sand filter in this system water from the pool is forced through sand and then returned to the pool minus many of the impurity's that enter the pool from the air or bather activity. Sand was the original filtration medium used for this type of filtration however better medium for this type of filter are constantly being developed. this type of filter is cleaned by what is referred to as backwashing occasionally and some water in the pool is sacrificed to waste

2 another very popular system is the cartridge filter In this method water is run through a diaphragm that filters out impurity's one advantage with this type of filter is that to clean it you merely expose the filter cartridges and hose them down removing contaminants collected by it.

Diatamatious earth is based on the fossilized remains diatoms. water is forced through a layer of this material inside the filter this is the finnest type of filter, and will require more attention then the others as it will block up more rapidly. ---- Hayward makes all three types of filters listed above:
