The high pressure does the cleaning - you don't need additives.

Then can you explain this item?

Seems it might make a medium-duty pressure washer more effective at
cleaning concrete or brick, maybe with a lot less water usage and no
chemicals (although I don't see why it should cost $200).

Never seen one before but as stated and shown with the small tip,
it's use is for spot treatment of paint/rust removal, not general
cleaning.
