Your cleaner is a Letro Legend with a fancy body. Low pressure on the filter can indicate a clogged skimmer, pump basket, impeller. This will result in low water flow and everything is dependent on the proper amount of water flowing to work correctly. Also, check the wall screen for the Letro for blockage. Except at extremely low water flow conditions a booster-pump powered cleaner should continue to work. That's one of the reasons they are my preferred choice in type of cleaner for most all pools.
