Biggest Problem with Anker and Eufy vacuums - replacement parts

I have the Eufy Robovac 11s Max. I am trying to find replacement filters to purchase but I don’t see any for sale on amazon. All the filters are for the 11. Where can I find new filters?

According to Eufy, this is the right part:
B07W5VZRRW
I searched it on Amazon tonight and ordered this part set, which has 2 filters, some spinners, a rotating brush and guard.

I could not find just the uni-body filters anywhere, although all these other parts are available on Amazon singly.
Not a good way to do business.

Anyone know if the motors for the 30c are the same is the 11?

In case anyone is looking, these did fit my Anker Robovac 10.
