Like Jason said, what matters is the clarity of the water, not some rule of thumb turn over per day unless you are in a commercial regulated environment. This is different for each pool depending on amount of debris blown in, pool use, etc. So our general suggestions for variable speed pumps is run it as slow as you can and still maintain good skimming action and keep your equipment (SWG, Heater, etc) that requires a certain amount of flow happy. In the case of your suction side cleaner this will probably be a higher level than everything else and you will probably need to program enough high speed run time to keep the bottom clean. Then just cut back on run time until you start seeing water clarity issues, then turn it back up a bit.

p.s. it is best to do this fine tuning with a somewhat dirty filter so you will not drop below minimum flow requirements when the filter gets dirty
