There are three basic types of pool cleaners to choose from which fit different needs and budgets. Pool cleaners work significantly better than simply using chemicals for cleaning, as they continuously clean out dirt and debris from the pool throughout the day. Suction pool cleaners are the most popular type of cleaner and are also the most economical. The hose attaches to a skimmer or side port in the pool, and suction is generated from the pool pump. The cleaner moves around the pool in random patterns and puts the debris into the pool filter. It is easy to install and maintain, however it does not work well in gathering up a lot of leaves. Its suction is dependent upon the pressure from the filter, so the filter must be kept clean.
Pressure pool cleaners are more expensive, but they can work more efficiently. The cleaner hose attaches to the pool return, which is where the water flows into the pool from the filter. It runs off an additional pump, or booster pump, to push pressure through a line into the pool to the cleaner. The force of the water creates a vacuum and propels the cleaner, and dirt and debris are deposited into the pool's filter or, more commonly, into a bag. The use of the internal bag means dirt and leaves can be collected without clogging the filter. It also distributes filtered water into the pool. The pressure cleaner is more difficult to work on and install, but is more convenient to use when put together.
Automatic, or robotic, pool cleaners are the most efficient type of cleaner. They get power from and electricity connection from the home, using a transformer to convert the electrical current to a safe level. Automatic cleaners run on a timer, which is usually one to four hours, and they get the cleaning done in the least amount of time.
Robotic cleaners come with their own filtration system. They do not attach to a pool pump or filter. It is thrown in the pool when a cleaning is necessary, then taken back out. It helps circulate the water in the pool and has an internal bag to store dirt, leaves, and other debris, which is easily removed. Because of its independent system, it is simple to install and adjustments are not necessary.
Automatic cleaners do the most effectual job at cleaning, and some even scrub the bottom of the pool. Their portability, along with the ability to operate many models with a remote control, makes them the most convenient choice. They are also difficult to work on if they need to be fixed, and are the most expensive type of pool cleaners for an in-ground pool.
