I have one of these filter robots. So far, I really like it, but it is slowing down, stuttering, and sometimes stopping. It is about two years old. I disassembled it partially, and there are no obvious obstructions, and the vacuum gauge reads plenty of suction. No strings, rocks, or anything.
The feet seem to be wearing. Other than that, not much signs of obvious wear.
Anyone know of a website that has a guide to troubleshooting or an exploded diagram ?
Anyone have any experience with servicing these?
