Zodiac MX8

I bought a brand new MX8, it never worked. Moves for 2 minutes then stop. I have a 1.1 Kw pool pump that shows max flow on a flow meter. I tried every possible flow strength. Stay away from this product. a Complete waste of money. I replaced it with a R599 Voyager Pool cleaner and there is no comparison. The MX8 is back in its box lying in my garage, completely unused.
