I had an aquabot rapids 4wd and I bought a dolphin active 15 for my 18x33 oval above ground did I make a good decision the aqua bot has been great for 5 seasons and just quit this week.
I think it will work great, I know it says it if for inground pools but yours is still a vinyl pool... It may have a harder time climbing the walls but it should have no problem cleaning
