Now, attach a spray gun to your garden hose. You basically reduce the flow to about 5 gallons per minute. As a result, the water pressure increases from 10 PSI (pounds per square inch) to 40 PSI.
Just by adding an ordinary spray gun to your garden hose, you’ve increased the pressure by 4 times and simultaneously reduced the amount of water used.
Here’s the problem. The water pressure isn’t strong enough to actually clean anything. It just pushes stuff around and gets your socks wet.
A pressure washer takes the same principle to the extreme. It uses a gas-powered engine or an electric motor to exponentially boost water pressure to 1000 to 4000 PSI. We’re talking about serious water pressure that can actually clean stuff. Fore more information ,please visit http://www.bossgoo.com/
