You may try lowering the water flow rate into the above ground skimmer and switching more pump power toward bottom suction and let Betta the mobile skimmer do pool surface cleaning. With reduced water flow into the above ground skimmer, Betta should be able to drive by the opening without getting stuck.

Alternatively, there are a few potential solutions that may prevent Betta from getting stuck. We kindly invite you to watch the video below for further assistance.
