A good automatic pool cleaner is very important in reducing the amount of time a pool owner spends in cleaning his/her pool. They are probably the single most popular option. Don’t expect them to do 100% of the job. They will vacuum the pool and stir up fine debris but they won’t brush the pool sufficiently. Use them to maintain a clean pool clean, not to clean a very dirty pool. They should be used only as needed, not continuously. They could scratch the liner under certain conditions or if overused. A scratched liner is usually not covered under warranty. Refrain from using your cleaner until the deck is done and your pool has gone through the final cleanup because a high concentration of debris may damage it.
