    Bought this to replace a worn, elderly vario lance ( approx 10 +years old ). This works so much better re smoothness, ease of attaching, and seems to produce more total pressure. Much quicker to turn down pressure for soap emission.

  • Q my old hose was damaged fitted new hose but do not get same pressure is this a problem with new hose or is a new lance required if so what do I order 1 Answer

      The high pressure should not be significantly effected by hose length due to the low volume of water used. This lance can vary the output jet size thus varying the pressure and force of the jet.

  • Q Vario Lance 1 Answer

    I have a Lavor pressure washer but vario is faulty. Would a Kacher Vario fit. I have a karcher adaptor for a patio attachment.

      If you have an adaptor to fit a Karcher patio cleaner the Vario lance will fit into it.

      Yes a new one will fix the problem, it is not a fault with the washer itself.
