Obviously chinese washers work fine as well.
But my whole point in all of my posts while supporting Karcher has always been that these items are not bought everyday. Therefore atleast buy something which is authetic especially if the difference in price is not much. And then some random XYZ guy jumps up and starts thinking I work for Karcher lol.
I bought Karcher K2 for 12500 3 years ago. At that time a chinese washer was for like 9000.
2-3k rupees should not matter much when someone is buying a product for long term use.
