Karcher extension hose,
Verified Purchase(What is this?)
This review is from: Kärcher 6m 6390-243 High Pressure Hose Extension - Pressure Washer Accessory For K2 - K7 Series Machines (DIY & Tools)
Having ordered my Karcher machine at the same time as my extension hose from the same source I was not too pleased to find they were not compatible. Nowhere could I find that information, and I have wasted my money.
