Polaris 3900 not moving or moving really slow

[Heinsite]

3900 cleaner that was a few months old not moving, plenty of water getting to and coming out the tail end.
I had this problem and fixed it after a week of trying different things...I could not find any reference to this issue on the internet. The issue ended up being debris in the small jet that shoots water on the paddle wheel to make the unit move. It was clogged and after i got it moving, one of the water jets got clogged causing it to run sideways and spin. We have a lot of leaves in our backyard so this time of year we get a lot of them in the pool. This created a major headache for me until I tracked it down...hope this helps other...real easy to fix, three screes on bottom take the cover off, then three more to take the water flow section off..The back silver grill comes off with this part.

You shouldn't be getting debris in the unit. The unit operates, or should operate with water directly from the filter, and there should also be a screen near the wall fitting on the feed hose to catch any debris that get past the filter. Is the filter running when the Polaris booster pump runs?

the little screen filter near the wall fitting sometimes blows out at the end resulting in debris continuing into the cleaner.

Is there a thread or a page entitled “ I hate Polaris 3900s”
I’ve replaced the entire inside drive chain, I replace the entire hose system. And the thing keeps on getting stuck at every corner. So the option now is to throw it out and get a different brand or somehow persevere if someone has any assistance.
