Thanx for all your replies guy's

i've decided i'm gunna go with the techclean to start me of...but one question before i order,,,if i was to get a hot pressure washer instead ( as graffitti removal is the path i want to go down and driveway cleaning would be just an add on ) could i and would it be powerful enough to use a f.s.c .. Also as its graffitti removal i wanna do , could i get away with running from a ford ranger or some other kind of pick up,,or would i be better of with something like a fiat scudo or some other van

...kind regards, shaun
