Good afternoon! Hoping for some input on robots vs automatic pool cleaner (suction type). We have an Intex 16x32 Intex AGP - rectangular. If we went with a robot, it would need to be on the lower end ($300 or less). What are the advantages to the robot for the extra $$? Our pump is .6 hp, so that does limit us some on the suction type. I do love the idea of the robot, but I'm trying to justify 3-6X the cost. Any help is greatly appreciated.
