My C120 is 1200W, I think!
Also, yes the hose is a little short, another 2m would help for not having to move the washer when doing the car, I have to move it from one corner, say the back, to the opposite back corner to make the hose reach far enough to wash the front corner. No issue with the quality of the hose though. Agreed, a longer one would make it the perfect buy!
