Which routers support the Time Machine feature?

Hello!

I'm looking for a router that supports the Time Machine feature for someone else. Now I know that the Nighthawk R7000 router does since I'm able to find a tutorial in the Internet. The X6 R8000 apparently does too. Is there a list that shows all the routers compatible with Time Machine or do I actually have to look up routers randomly and check their manuals to determine whether they support Time Machine? Probably the latter, right?

Thank you very much!
