thanks for the info, sorry for delay in replying to my own post!
RSMAT, I did wonder if it was worth it.
My problem is my current p/washer is a B&Q make, I have looked at the fittings and it is close to a Bosch one but not the same. Also it will need replacing soon as its leaking internally, the one I would really like is a Bosch Clic 125 but I do not think the snow foam lance will fit this anyway! Thats why I thought of a normal hose pipe version.
Is there a cheap (£30) p/washer that any one can recommend that has the correct fittings for the Gilmour foam lance?
