Well as a follow up to my last post firmware update, I was able to observe the S1 running today on floor only Eco mode and disappointingly the S1 would not advance past the incline to the shallow end.
The S1 spent 30 minutes of its 45 minute cleaning cycle traversing the same path back and forth across the pool, the same location where it would get stuck before, then shut down.
I followed up with the same Aiper CS rep that provided me with the firmware update to share my latest experience.
While I think the firmware update did improve the operating parameters it unfortunately has not completely solved the "incline challenge."
