I'll be looking forward to hear what he does to your system or has to say about optimizing your setup. Please let us know!
As for running "The Pool Cleaner", do you have separate return lines (apart from the in-floor heads)? If so, the heads will be retracted almost completely flush with the pool surface and the cleaner will just roll right over them. If you don't have separate returns, maybe you can set the in-floor heads on the step/shelf area to remain on continuously (lock that zone on) and manually point the head discharge to point to the middle of the pool. Then the cleaner would have unrestricted access to the entire floor area. Obviously, you'd need to manually brush the step/shelf area to keep it clean - as the cleaner probably won't climb up there anyway.
How would you connect the cleaner to the system? Is there already a built in vac port or would you connect through the skimmer?
BTW - my daughter has "The Pool Cleaner" 2 wheel model and loves it. She runs it 2-3 times a week for 4 hours. It keeps her 13,0000 gallon play pool quite clean.
