How much they can see depends on what the router retains so the model might allow you get get more accurate responses. Generally, routers that have logging turned on will just retain IP addresses along with some metadata about the packets like time, direction, etc. More robust routers will also retain DNS requests, URLs, etc but very few of them have the capacity to retain them for very long because those logs just keep growing.
