Karcher - Never again!

Words cannot express my dissatisfaction with my Karcher K4.68 high pressure gun. It was repaired December 2019, was used only on 4 occasions to wash my cars and broke again September 2020 - exact same problem as before! Although the December invoice state 2 year warranty, I was informed it is only 3 months (nowhere stated on invoice...) and that I have to pay for repairs again. Karcher products and service are definitely not as good as advertised and better to rather purchase another brand!
