Modern Technology
This machine comes with an LED display to make it easy for you to control and select the water pressure you want. It uses two AAA batteries to work and uses signals that can enable you to know where the pressure is and where it should be, up to 130MPa. That’s a step up from the K2 which outputs 110 bar, but short of the 170 bar produced by the K7.
The full control Vario Spray can be used at different pressures to suit whatever purpose you may need it for. Thanks to the guidance technology of the machine, this makes the entire cleaning experience much easier. The full control gun, along with the two spray lances, can be attached to the machine and stored there. The hose can also be easily stored wound on the hose reel that exposes as much of the hose you need and then allows you to reel it back in when you are done, but it’s not as long as on higher-end models. The K5, for example, has a handy 8 metre hose.
The machine also uses what it calls a ‘Plug n Clean’ detergent replacing system that can not only save time but also allow you to apply the detergent on any surface quickly before having to subsequently clean the given area.
Durability
The K4 is a pretty durable machine with a good way of containing the accessories like the hose reel. It also sports a strong, sturdy exterior that can handle some rough use if needs be. For stability during mobility, the machine has a front foot that can prevent the machine from tipping over.
This pressure washer is also easy to manoeuvre, with its high impact wheels and aluminum telescopic handle. This machine is very durable, therefore ideal for long term and heavy-duty use.

Performance and Conclusion
We consider this a good multipurpose product and like how small it is given the amount of pressure it can generate. Opinion is divided about whether it’s too heavy or not. I say not, but my partner disagrees with me.
The initial assembly and setup can be a little difficult, but if the instructions that are provided are followed properly, then the assembly is straightforward. Additionally, using the K4 is very simple and anyone who tries it will be able to get it going, whether they are experienced or not. In terms of performance it’s what you’d expect from a Karcher – outstanding.
All in all, it is a very useful and heavy duty product to have around the house. It is a bit on the pricey side, so anyone thinking about purchasing it should give it some thought, but in my mind it’s a long-term investment that will pay off for many years to come.
