The Pool Cleaner

[Russmd]

I have a the pool cleaner, four wheel model on my inground pebble pool. The suction source is a dedicated port in the middle of the pool. Because of plumbing issues beyond my control, long runs, and many bends, my suction level at that port is not as high as I believe would be optimal. I do what I can to get the cleaner to move well but it’s slow. My question is, does the size of the throat inlet, small, medium, or large, make a difference in how efficiently it moves? Does the small or medium throat make for higher flow speed through the turbines making it move faster,, or do they restrict flow more than the large making it move slower, such that the large would allow more water to go through. Yes, I can try the different options, but I was just looking for some physics ideas to improve things. thanks in advance.

Additionally, mine just likes to hang out mostly in the deep end. Hose floats are in position, leaf cannister is floating, jets are aimed down. Fixes for that too?
