I have the Pentair Kreepy Krawly Sandshark. It’s always worked well in my pool. It’s a stupid-simple internal design that is easy to fix. The only addition I made with it is to always use an inline leaf trap to avoid suction like clogs. Other than that, it just works. It gets hung up on the drain covers but so did my robot and probably any other cleaner on the planet.
I will likely try a Rebel when the time comes to think about replacement. This current unit is only 2-1/2 seasons old so it’s not going anywhere anytime soon.
