- Remove any obstructions from the pool walls (ladders) if necessary. The robot could be hitting the obstructions and falling backwards.
- Clean the filter baskets, they may be clogged. Try running the robot without the filter baskets and see if the robot operates normally.
- Check the handle buoyancy. Place the robot into the pool, the handle should stand straight. If the handle falls over, the handle is damaged and may need to be replaced.
