No dont do it
waste of money imo,I have a really small Karcher one that I have had for about 16years.In totall it has cost me maybe £15 for the turny thing on the end of the lance.That's washing my car probably three times a week and I do motocross and so does my lad and that used to be every week.In all fairness mine is an old industrial one because my mate is an engineer for speedclean and they are karcher specialists.Everyone else I know has got through probably 4 of the b&q or whatever in a lot shorter time.I give £60 for mine all that time ago and its still mint.The realtime for the hobby washers is only about 40hrs I think.
