Hi everyone! I'd like to introduce you to Christine:
We inherited Christine from the previous owners of our home/pool. We think she is a Polaris (she has a Polaris booster pump) but all of her identifying features have been aged right off of her. Like her namesake, she's an oldie but a classic. Also like her namesake, sometimes she has a mind of her own. She enjoys running down frogs (we once found a frog leg wrapped around one of her axles), flinging off her tail, flinging the scrubber off her tail and sometimes... she just goes on strike. That's what brings me to you fine people, today!
When I take her out of the pool and inspect her, I can't find anything unusual. Her wheels move, no visible obstructions, everything seems fine. In the pool, her jets are functioning. There's water coming out of them at low pressure when the booster pump is off and higher pressure when it's on. Her tail is whipping as usual, but she's moving very slowly around the pool and when she encounters a wall or the stairs she won't climb anymore. She just gets stuck and sits there until I come out and rescue her. I disconnected the hose from the wall and pulled out the little debris screen. It was dirty so I gave it a good wash and put it back, to no avail. I checked it again just to make sure it hadn't become immediately clogged again, but it looks fine.
