Polaris Raptor - Not Recommended

[waterbear]

Polaris does make a drain cover that fits over the drain to allow cleaners to move over the drain without getting stuck.

You might get good results with a pressure side cleaner like the polaris 360. It does not require a booster pump.

Thanks, Evan. I'll have to check that model out. They recommended the ATV - a suction side cleaner that does not have the same issues as the Raptor. Still, I think I'd just like to make the investment in the robot.
