Nighthawk XR1000 and Mesh Help

you can use mesh extenders but I usually advise people to avoid them and go with a full mesh system if they think they're needing more than 1 extender. 

how many do you need? Depends. Each home is different. the nice thing about mesh system is you can add satellites pretty easily. 

The XR1000 isn't a mesh router. so it doesn't integrate with mesh systems. 

If you're wanting to retain the gaming features of hte xr1000 but have a mesh system, you can always add a mesh system like orbi to it and run the orbi in access point mode. 

then you retain the benefits of the DumaOS while still having the coverage of orbi.
