Looking to buy pressure washer - what bar and wattage do I need to clean slime from patio & garden furniture?

I've got a 1500 psi (don't know what that is in bar...) which does the job very well.





For cleaning large areas of concrete/patio slabs I would go for a higher psi if I have to buy a new one - if the cost was not much extra.


Here's the reason:- When cleaning large or difficult "old" patio areas you have to concentrate the water jet down very fine to really cut through. With higher psi you would be able to keep the water jet further away, so you clean a bigger area quicker.





HOWEVER you only do this infrequently, so if cost is important, 1500psi is more than enough.

Reply:Any pressure washer should do it
Reply:Any pressure washer over 1000 psi. would do, I bar is equal to about 14.5 psi (pounds per square inch ) 800w would be OK
