How Pressure Washers Work


You probably already know that nothing else beats the quick and efficient outdoor cleaning results you can achieve with a pressure washer. Dirt, grease, mold, dust, salt, moss and stains are blasted away!

So, to help you choose the correct model, and get the best results from your pressure washer, it's worth taking the time to review how a pressure washer works. Different pressure washer models will vary slightly, but the basic concepts remain the same.

And you can see my top recommended gas pressure washer: the Generac 6596 on Amazon.

The average pressure washer used by DIY/homeowners provides a pressurized water stream that is up to 50 times more powerful than your ordinary garden hose!

But here's the best part: because the water is highly pressurized, and ejected through a small nozzle, you actually use LESS water to clean! Up to 70-80% LESS water than a regular garden hose. Sounds great, doesn't it?

HERE'S HOW PRESSURE WASHERS WORK:
