Nilfisk branded and Gerni(Consumer) Click and Clean G4 long lance complete. formerly Pn. 126481135 and before that Pn. 6411715
Click&Clean C&C is a method Nilfisk-ALTO and KEW and WAP and Gerni use to connect accessories. There are different Generations and they won't always connect together over cross generations in the photo, the G4 is on the left.
These can't be connected together to make a very long lance (use Pn. 128500389 for that purpose) because, the male end fits into the pistol grip, and the jet/nozzle fits into the female end.
