Had a Karcher that never missed a beat over 10 years before it died so decided to buy another one. Bought a new K4 Compact from Bunnings as I was impressed with the water cooling design but how wrong I was. Karcher definitely don’t build them like they used to. I only used it to wash my car once a month for 9 months before it bellowed water from within and no longer held any pressure. Still under warranty right? Sent Karcher an email with all details and pics and still waiting for a reply?Looking at all the online reviews across the Karcher range, I didnt really want a replacement for it to fail again. Steer clear peeps, no longer a reputable company or product.Bunnings however, were fantastic and honored the exchange to another brand almost a year later. Thank you!
