These are spare/extra heads for a Karcher window, VAC. They originally came from a culture VW 75 plus. Please note that the picture of the box is for information purposes only. There is no body to a window vac included in the sale. Four heads. Spray bottle plus the head which goes on the spray bottle. I’m sorry I am not a Karcher window vac expert, I don’t know whether these parts will fit your window vac. Please look at the photos and decide.
