What size of surface cleaner are you going to get?
What are the gpm's and psi of your machine?
You need to match up the gpm's of your machine to the size of the surface cleaner.
If you are thinking of a surface cleaner with casters, think again, a little rock or something will stop the caster and mess you up.
If you are thinking of a surface cleaner like the big guy but only have 4gpm's, I would think again.
There have been a lot of posts about this, don't make a mistake and get a surface cleaner that is more than what your pressure washer can push.
