Hi there,
I live in South Carolina, and I built myself an inground pool in the backyard of my house, close to 800sq.ft. It is rectangular and 2 meters deep.
In the two years since I built the pool, I have always done light cleaning myself every day and then deep cleaning up to twice a week.
At the end of May, I ended up with a cordless pool robot on Amazon, which came up as Best Seller in my search. So far, so good, no cords, cleans as well as I could have hoped, and my family is happy with it.
This is my experience, and I hope it will help you.
