There is. It's called a Terrazo grinder. Or is it terazzo.No, it's
Terrazzo. Anyway - it does exist. Terco and Oztec are two names.
Check local concrete and flooring contractors - most of the good ones
around here are either Italian or Portugese.

Yes, I saw one of these used on _This Old House_. Memory fades
but it looks and was being used like a floor buffer on a wet
surface. Looked to be a very slow process too, they didn't have
a very large area to smooth and level.

Smoothing is one thing, to level the floor you need to establish
some sort of reference plane to check the floor against. A laser
level might be good for that.

Concrete is much easier to smooth and level when it's still wet.
