Retractable shower door - self cleaning

[foyleman]

I have a 2022 Alta 2350KRK with a retractable shower door. I believe Recpro makes the door as it looks exactly as this one:

It's supposed to be "self cleaning", but I don't see how that's possible I don't see a built-in wipe. I can clearly see that the door rolls itself up inside the track.

I can't find any online images or pictures of the rolling or wiping action as a comparison.

I'm curious if my shower door is missing a part.

My guess would be that you have one of the other 2 retractable doors that they make and they don't have the 'self cleaning' feature. https://www.recpro.com/rv-showers/
