The track on my cleaner keeps falling off. I had problems with a previous P825. I took it back to Leslies and they tried to fix it but couldn't, so Leslies finally replaced my cleaner with a new one. Now it is several years later, not sure how long (as I am in a COVID fog regarding time). At any rate, does anyone have a solution. I have not been able to find one. The owners manual does not address this trouble.
