Fantastic plastic. a review by Rickam

In my case I have had three different K2 units die in the same way. The black plastic housing cracks and the unit pulses, loses power and leaks. When the K2 is running, it works quite well.

After conducting an autopsy on each, I would say that the technology looks pretty good, but Karcher should provide service parts for this device (they don't), and at a reasonable cost. All the units I have owned have not lasted very long at all in terms of hours, or days from purchase. It may be superstition, but they tend to last a year from the date of purchase.

Another possibility of why my units failed is how they are handled in transport. ALWAYS DISCONNECT BOTH HOSES from the unit during transport. The long black ABS goose necks (they don't look long with the Karcher Yellow shroud - but they are!) that attach to the lance hose and supply hose can gain a lot of leverage and crack the pump housing. Those hose fittings are the Achilles' heels of the machine.

The same tip can be used for laptops or anything with plug in cables or power supplies. Unplug everything when you transport a laptop. I still don't know if it was my fault that all my karchers died. But being the curious kind. I keep buying them - "The Devil that you know"
