@proavia what do you think about this?
Sounds like previous owners didn't take very good care of the pool or any of the equipment - and the pool inspector doesn't know how an infloor system actually operates.
I am guessing that post #51 is what the pool inspector wrote. I see a lot of misinformation in post #51.
A properly functioning infloor system doesn't push dirt and debris to the sidewalls. Actually, the infloor eventually pushes dirt and debris toward the main drains. While not a perfect system, most all dirt and debris gets to the main drains for removal. If the system only pushed dirt and debris to the sidewalls, none of it would ever get removed from the pool by the system. Based on the condition of the infloor system components - water valve, cleaning heads (pop-ups)and water pressure/flow - the system may not be working at optimum efficiency. Only the OP can determine if it is more cost efficient to fix the infloor or abandon it and replace with a good quality robot (not a suction or pressure cleaner). But first, the OP needs to fully understand how the infloor actually works and not take the word of an inspector who obviously doesn't understand infloor systems.
Request a picture of the water valve for the infloor. Is there a pressure gauge on or near the water valve? Is this a top feed or side feed water valve? If the pop-ups are extending and staying up and/or only some zones work, chances are the water valve internals are stuck or broken. The heads on one zone should pop-up for 45-90 seconds and then retract (as they retract, they rotate slightly), then the water valve should open the next zone. Once the system goes thru all zones, it starts again with the original zone. Somethings a particular zone may come on again before a cycle thru all zones completes. We can help diagnose that, but need to know what water valve is being used.
There is a lot going on with this pool - much of what needs to be fixed and/or reprogrammed. One thing I don't see is any accurate test results. I have seen statements of the chemicals are good and requests that the OP get one of the recommended test kits -
Test Kits Compared - but haven't heard if that will ever happen. Unfortunately, this pool will probably go green while we are trying to solve other problems.
Does the OP have a recommended test kit or have one on order?
How is this pool being chlorinated today?
When was the pool water last tested and by whom?
What test kit was used?
What are the current results?

Request the OP fill out their signature with pool, pool equipment (including manufacturer and model numbers) and test kit info so we don't need to scroll thru 50+ posts to grab a tidbit here and there about the pool and equipment. Having it in the signature assists us in helping you.
A bit of dirt and debris because the infloor isn't presently functioning well isn't going to necessarily turn the pool green - but lack of chlorination will.
Sorry for the blunt/brash reply, but first things first. While some of the issues may be related, trying to tackle all at once can lead quickly to even more frustration with the pool.
