    I found locating and ordering off the espresso website simple - just put the product code in from the Karcher information sheet and there was my item. The price was great too. But best of all is the email communication keeping me posted about delivery and stock - simply superb. Now my Karcher looks like new. I will definitely order from spares again!

    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.

    Very useful accessory to my pressure washer, reduces pressure at a twist for those places that don't need too much of a blast !

      This could be used but is desined for a higher flow so Stock Number: ES659756 may work better.

  • 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.
