I bought karcher k4 as unfortunately, that's the only reliable pressure washer we have available in Pakistan apart from the Chinese ones. My shashkay may as well be poles apart from your requirements or maybe they align, I don't know. I wanted higher GPM so the foam cannons would produce thicker suds and so on. K2 does the job too for an average user. I believe you can get one for as low as 11k on today's 11/11 sale on daraz.
