My 12 year old Karcher K2 developed a tiny crack in the piston manifold. So started looking for a new Karcher and picked up this refurbed K4 last Sunday. Product arrived on Tuesday in good condition, was a little dirty which is acceptable for a refurb that's $200 cheaper than what others are selling.
It looks like there is a 12 month warranty.
5% discount off $389 with the promo code.
My K4 has shit itself already, just after a year.
