Karcher pressure washer K6.50

[Ian - g4jqt]

I'm looking to buy a pressure washer soon. Any advice on which ones seem to be reliable? Is the Karcher range known to be reliable and/or repairable?

Comparison sites often rate items on the grounds of features/price, but don't help much when the things they've recommended fail after 18 months and are either not designed to be repaired or the spares no longer available.

Thanks and regards,

Ian
