I tried out a Pentair Warrior and it got stuck. I was able to return it to Marina. I heard that there is not much difference between the Maytronics models except the plastic body. In spending days reading reviews on Amazon, it seems that every cleaner gets stuck. I bought a device which covers the train and adds a more gentle lift but the Warrior still got stock. So anybody had really great success at one NOT getting stuck or can steer me away from one that does? Thanks. I need to update my profile, but 27,000 gal pool, L or Boot shape, 33 feet long. Inground.
