Auto cleaners are terrific time-savers, and they also help to distribute and circulate the water while (some of them) decreasing the work load required of the filter. There is a wide range of cleaners available, for all types of pools and budgets. Cleaners run from $300 to $1,500. The more expensive models will vacuum more debris, more efficiently and without compromising the filter system. Refer to the auto cleaner section at The Pool Janitor's closet
