Hi

Recently, our Dolphin supreme M4 pro has broken down. When we turn on thé robot he turns to thé right 90 degrees and then turns back to thé left 90 degrees to thé starting point. His light on thé dock outside thé water is still burning. We have checked thé filters en checked thé inside of thé robot. But he still does thé same thing every time again.
