I have the Aquabot s250
The yellow one with 4 wheels for my 16x32 oval A.G pool.
Prices range from 375 or so to 475 depending where you look on the net, even walmart, bought mine through WayFair only because I had enough " reward points"
Plenty of cord ,I think you might even be able to order 2 versions, one with a shorter cable or longer .
The elastic band on the 2 bags will deteriorate after 2 years and will not stretch tight around the inlet ports.
I now use zip ties for those.
Will run for 1 or 2 hours, doesn't climb walls,after running for awhile always wants to stay in one end of pool so you will have to re position at the other end.
Doesn't pick up silt, but then I have found nothing that really does other than my pool blaster and installing a micro bag and in that add a skimmer sock,works well but clogs easy.Hate to drag out vac. hose and lose water.
Never had a problem with the Aquabot.Cord very rarely if ever tangles.Comes with 2 styles of bags, always used the finer ones, I don't have trees to worry about leaves or larger debris.
Always, as with anything open up and let the sun dry out when finished.
I wish DeWalt would make battery operated vacuum, one that actually runs as long as they claim.
