Can anyone recommend a reliable automatic pool cleaner robot that will work well in a dish bottomed ABG pool that's 16'x32' and 4.5' deep and doesn't break the bank? We really liked the performance of the Aquabot S2-40 when it worked, but clearly there is a quality issue with this model as I've described below. Any suggestions by persons with 1st-hand experience would be greatly appreciated!
BACKGROUND: We purchased a brand new Aquabot Pool Rover S2-40 off Amazon for ~$300 a few months back. From a performance standpoint it worked absolutely great for about 4-5 weeks, with a few exceptions where the cord either got tangled or it got caught up on the steps in my Intex Ultra Frame 16'x32' rectangle pool w/ SWG. Overall though, it kept the pool squeaky clean when it worked. However, about 2 weeks ago it failed; it would run for a few seconds and then stop in the middle of the pool and the transceiver's blue led lights would synchronously flash. I got it RMA'd through the online seller and within a few days had a brand new replacement unit. Immediately, the replacement unit failed with the exact same behavior as the first. I wrote the seller and asked for a full refund which we're in the process of obtaining.
So, where do we go from here? I want my pool to stay as clean as possible but I don't want to spend more than is necessary to do so.
Suggestions? I appreciate everyone's thoughtful insight.
