We just purchased a home that has been vacant for two years. As you can imagine, this pool is TOUGH to clear up, as it has had two summers without maintenance, and had been able to become a green, gunky, algae filled nightmare. We purchased the Polaris 280 from our pool company suggesting it. We wanted to get it installed ourselves to save the extra $200 they would charge. My dad helped my DH get this thing setup as they have had an IG pool for 12 years, and he knows his way around a pool, so incorrect installation is likely not the case. It has been in the pool for a couple of days, and is definitely pulling things up. The weird thing is it doesnt seem to be moving very fast, and ONLY stays in the deep end of the pool! We have moved it to the shallow end, turned it on, and it goes right back to the deep end, and just seems to be going in circles in the same 4x4 area. My parents have a similar pool to ours and the Polaris 280 and theirs works wonderfully. Are we missing something in the settings, or is this one just a lemon that needs to be exchanged? PLEASE HELP! We want this pool to be swimmable by Memorial Day, and in the past two weeks it has only made the progress that most pools opened in MN in the spring have in two days!
