So after many years of use my "the pool cleaner" vacuum finally bit the dust. I was happy with it, was heading over to amazon to buy another one and made the mistake to check the forums to see if there is something better lol. So I found the Dolphin Nautilus CC on amazon for $579 which seems like a good price compared to $370 for another "the pool cleaner". I'm looking forward to closing the vacuum suction line and having full suction for my skimmer. Is it worth the extra $200 dollars? Do i have to clean this vacuum very frequently? I only had to clean the attached basket like once a month on my suction vacuum. Can I just leave it in my pool 24/7 and pull it out when we want to swim? Is there any better ones in this price range? I would kinda like to stay below $600. Thank You in advanced
