Will Netgear Orbi work on Vodafone FIbreX

I am on the 1Gbps FireX plan with Vodafone and am looking to get into one of the Mesh wifi solutions that are out there.

I like the look of the Netgear Obri as it seems to provide:

a) one of the fastest wifi solutions

b) doesn't require a login to any of the vendor's own cloud based tools or have any remote chance of any network traffic being discoverable by the vendor (or am I wrong here?)

c) is on special at Noel Leeming at the moment for $639

But I'm not sure if its just a case of removing the Vodafone supplied wifi router and replacing with one of the Netgear Obi units? Is it easily done and are there any downsides?

Also as an aside, anyone know what the theoretical max wifi speed of the Netgear unit is?
