My knowledge about networking is fairly limited, but from a consumer perspective it works really well with seamless roaming, especially compared to old wifi repeaters. The Orbi system uses a dedicated backhaul to connect the nodes. Since by parents' old house doesn't really allow installing network cables, this seemed like a good solution. In my home, I'm using a wired backhaul, which is the prefered option if possible. My only critisism is that the Orbi Wifi 6 system is quite expensive and there probably exist cheaper options to achieve the same.
