When we ordered our soft sided pool (Legacy brand not intex)...the company asked if we wanted an automatic vac. We had them bundle it with the pool and send it to us. It's a splash a round leisure vac and in my opinion works terrible. Plus they overcharged us as I found the same unit on amazon for about $150 less than what we paid. I want a vac that is reliable, not too expensive, and something pretty much trouble-free. I would love to buy one of these Pentair kreepy kraulys because they've been around for so long and seem to get good reviews...however this unit I'm wanting is for an in-ground pool. Does it matter if you use an in-ground pool vac on an above ground pool? Is there something I need to be thinking about with this? Thanks!
