Aqua Products Pool Rover S2-50
The least expensive robotic on this list is the Aqua Products Pool Rover S2-50. But don't let the price fool you. This is a solid cleaning robotic that works in both above ground and below ground pools, has a kink-free swivel cable, and it will climb inclined walls. Although it has basic timer and shut off operations, so it is not very versatile, the cleaning functions rival the top rated models in any pool you put it in.
