What good is a surface cleaner for a pressure washer?

So I am new to pressure washing and I had some questions! I have seen a thing called a surface cleaner and it looks like it does the same work a pressure washer does but just easier and faster! Will you explain the difference between normal pressure washing and a surface cleaner?


Answer
When you say "surface cleaner", I assume you're referring to a device that hooks up to a garden hose, not a chemical treatment.

A surface cleaner can only deliver water at your water line's pressure. This should be between 40 and 80 psi (pounds per square inch).

A pressure washer has an internal, electrically operated motor and pump which delivers water at around 10 atmospheres (1500 psi).

A pressure washer will clean grime off that a "surface cleaner" won't. If all you have to clean is superficial dirt and debris, a surface cleaner should work just fine.

If however, you have embedded dirt debris, or moss, a pressure washer is what you need.

NOTE: Be careful what you use a pressure washer on. It can damage some surfaces and remove paint.

Is it ok to run a Craftsman gas powered pressure washer in the rain?

Just bought a Craftsman pressure washer. Gas powered. Briggs & Stratton engine. I believe it's a 190cc. Using it on a huge fence and deck. Forecast is for rain for the next few days. Really want to get the job done. Rain doesn't bother me, but is it bad for the motor?


Answer
The heat produced from the device running is enough to evaporate any moisture it comes in contact with, ie, light rain storm, inadvertant spray.
