I do both. Consider this. If you have dead algae, it’s best for the water to be still so that the algae has settled to the bottom and the Nautilus can pick it up. If your pool is running, it might stir up the algae and your Nautilus may never get to it.
Good review. FYI, this is the biggest POS out there. Well, at least the bigger POS I've had purchased. Expect the treat to go out every 2 years. The wheels bushings will require replacement every two years. Wheels, oh yeah, those two. Along with internal gears. And, if that is not enough, the motor assembly leaks and water destroys the board and both motors. $400 for a new motor replacement. Do I need to let you know how often it gets tangled up with it's own cord? A LOT! Overall, a waste of money. Unless you only want it for ....drum rollll. 2 years!
