I have a karcher which is about 3 years old.
Not very impressed with it i'm afraid. The lanceconnections that fix the various nozzles seem to be very difficult to move depending on the temperature.
last week had to replace the hose at a cost of £30 after it burst.
Thought about replacement but possibility of impending redundancy made me think better of it.
A lot of car detailers rate Nilfosk very highly.
