Bathroom vent doesn't appear to be sucking, so I want to open it and see if it's something to do with the fan. If the fan looks fine I think I'll have to hire a professional to check the piping to make sure it isn't clogged.

We have a fan like that. The external body pulls straight down a couple inches and hangs on a pair of wire, spring-like supports. From there, you can access the light bulb and a bit of the fan.

I haven't done it, but from there, I would assume you can remove the fan and get a look at the vent pipe. For us, the alternative would be to attempt to access from above via the attic. That may be an option for you.
