Surprisingly easy
I was somehow able to install this myself, believe it or not it was actually pretty easy. My neighbor helped me hook it up to power. Connecting the wifi and app was frustrating at first, but when I turned my router in the house off then on it seemed to work all of the sudden. It's been running about two weeks at this point and the pool is perfect and I like being able to look at the system and check it in the app.

Great product
Purchased the Autopilot salt system to replace the previous Autopilot system which was installed by the previous owner of our home 20 years ago. The clarity of the pool was immediate and very noticeable. It has cut down on the amount of salt we add considerably.

Questions From Customers

Q: My pool is 27000 gallons. Is there a benefit or reason to get the CS40, as opposed to the smaller CS30?

Asked by: Richard Donnell - 7/14/2021
A: Major benefit. The rule of thumb is that you should get a system with 1.5x to 2x your pool size. They are listed with MAXIMUM capacities, so you don't your actual pool size to be at the max.
