Kärcher's most powerful residential pressure washer! Now equipped with a Honda GX390 engine, triplex pump, VersaGRIP trigger gun and Remote Pressure Control.

The G 4000 OH, German engineered from the ground up, is a high-performance pressure washer designed for heavy-duty use. No job is too difficult for the G 4000 OH! It has many industry-leading features, such as a 390cc Honda GX Series engine and Kärcher's high-performance industrial-grade pump with brass pump head developed exclusively by our German engineers. Our customers asked us to develop a pressure control system that is as easy to use, resulting in our Remote Pressure Control, exclusive to the G 4000 OH. This feature allows you to work continuously without having to stop each time you want to adjust the water pressure. Other advanced features the professional will appreciate on this top-of-the-line unit include a VersaGRIP trigger gun, stainless steel spray wand, 10" pneumatic tires with metal wheels, a 50 ft. steel-braided rubber hose and a complete set of Kärcher's patented Pro-Style Quick Connect nozzles.
