The unit we use is the Pro S model, Same boiler as that one, but mine is missing 1 wand connection, the second detergent tank, and the vacuum.
While that one is about perfect for that type of operation, we do mainly paint correction and coatings. So we use it more for that "deep clean" that only steam can provide while minimizing "touching" things.
Its also been an amazing tool for that between polishing and coating to make sure you get ALL of the polishing and other "oils" from the surface.

16Bar/230psi, and able to run that out of both guns at the same time
then switch for "wet" steam and switch for "detergent" - We normally run something similar to Shine Supply Solution or Chemical Guys All Clean, but some sore of degreaser. Could drain this and use a interior cleaner.2
