Yeah, even we moderators ask for advice. My Dolphin is now not running right. It won't climb the walls too well, and it seems to get stuck in certain areas. The vacuum seems fine--this morning the bag was very full, but it seemed to get stuck in the deep end--it was there last night and there this morning--and parts of the shallow end still had junk in it.

I did check the tracks and brushes and impeller. All seemed clear. The tracks MAY be a tad loose but the directions are unclear on how to tell. The brushes don't look worn at all.

Using the remote, the Dolphin seems to be able to go anywhere, though I THINK it's a little slower--but I'm guessing on that. I was able to get it to climb a wall with the remote last night, but not this AM.

I DID have troubles getting it to sink last night--had to turn it over under water to get the air out--but it seemed to filter just fine--the WATER looks polished.

I have a true rectangular AG pool--16x40, with a 5.5' deep end--a hopper with ramped sides down to it. No bottom drain.

The Dolphin has never had a problem before. Any ideas before I call them?

Thanks!
