Hey guys im looking to buy a pressure washer for my dad this crimbo but im not sure what to go for. I've looked at Halford's own branded ones and they seem decent value for money? Karcher are the other predominant brand i've seen, how do these weigh against each other?
Also as a bit of an aside, am i right in thinking that as well as being able to use it to cleaning the cars they have enough pressure to clean patios too?

i hate to think what it does to paintwork on the average car that isn't protected/looked after...
