I remember reading that one had a "bottom only" option which would be ideal for my pool bc the Nautilus Plus I just bought always gets stuck on the seats around my pool. I'm now regretting buying this one instead of the other one (Triton maybe?) where I could set it to only clean the bottom so it wouldn't get stuck. I think for my pool this one would be best. It was only bought maybe 1-2 months ago off Amazon, do you think they would let me exchange it since I'm not satisfied?
