They're pretty much the same as a bn, I had one. They clean glass like a pro.
But... what if I told you they're highly aggressive and need specific parameters? Only eat certain good and have a tendency to suck on the slime coat of other fish?? Always research a fish BeFoRE you buy it, especially by mail... you'll be ok though, they're pretty easy. Poop like it was the only reason creation happened. What size tank?
