Spotted the Deal at Morrisons for £30 but can't get to one :(
Anyway, checked Karcher online and they are selling Refurb units with a 6 month warranty for half price. This can be extended to 12 months for £6 extra
Cheapest is the K2.14 for 34.94 delivered, however there are various other higher end models for similar good prices.
Pick of the bunch for me was the k2.65 for £47 delivered which comes with a patio cleaner as well.
Good bit of kit from an established company on the cheap.
