Karcher sent me a free Snow Foam nozzle and it’s utter rubbish. It’s rare that I come across a product I’ll actively go out of my way to help people avoid but this is one of them.
I bought a Pro-Kleen Lance on amazon which came with 5L of snow foam for about £30 and it’s infinitely better.
I love Karcher’s products, the K4 Full control is amazing, the WD 3 Vacuum is fantastic and so is their SC 3 Steam cleaner. The foam nozzle however is a waste of money. Save yourself some money and avoid it.
