Hands-Off Weekly Timer

An automatic pool cleaner should be automatic. A true weekly timer runs a complete pool-cleaning cycle on schedule — every day, every other day, or a few times a week — without you retrieving or recharging the robot between cycles.

Smartphone App Control

App connectivity can put scheduling, cycle selection and cleaner status on your phone, although the exact controls vary by model.
