Karcher Pressure Washer

[Sherif]

I know there are many threads already talking about pressure washers in general but I have 2 specific questions..
I've narrowed down my choices to 2 models from Karcher brand (no much better brand choices where I live and I don't want a gas powered one):
1- k2 model - 110 bar (1600 PSI) - 360 l/h (1.58 GPM) - $100.
2- k4 model - 130 bar (1900 PSI) - 420 l/h (1.85 GPM) - $300.
So for washing my Grand Cherokee only (weekly) and once to twice per month for home cleaning work, is the first option good enough or the second one is much better and worth the price?
Both models supplied with 6m (20ft) high pressure hose, can I buy another one and put them together with a coupler or will I have to buy a separate longer hose?
Feedback appreciated
Thanks

I personally will never purchase another Karcher product after what I have been through in the last year. I just received my 3rd replacement unit this year and it was bad out of the box. There customer service is excellent but there pressure washers have been a huge disappointment. I have the k 5.740 model if that helps.

Thanks Jerry!
The other brands available here are either less reliable (Made in China) like black & decker or huge machines (not suitable for my needs) like Bosch.

I have a K2 and it has been working fine for a year or so. Only thing is I wish it had a longer hose but it's not hard to move around. I figure 1700 psi is good enough for car and undercarrage cleaning. I'm satisfied. Guess you gamble on whatever you buy right.

Just after you select your Karcher model call Sun Joe and ask them to recommend you a model and explain to you why their product is better. My input is here...

I have the K3 740 and it works fine. I also have the undercarriage attachment which is great for the winter months.

I dont use it frequently though, maybe once a month.

I had a problem with an o ring on my k4.600 so I fixed it and now upgraded to the new k5 Eco washer. Its good but they are very similar to be honest.
