A pressure washer can turn ordinary tap water into a high-speed jet powerful enough to blast away dirt, mud, algae, and grime from concrete, cars, decks, and other surfaces. But how does it actually produce that much force? In this video, we break down the engineering behind a pressure washer and explain what the motor, pump, high-pressure hose, trigger gun, and nozzle each do. You'll also learn why water isn't simply being "compressed," how the nozzle helps create a powerful stream, and why PSI isn't the only number that matters. We’ll also take a quick look at the history of modern pressure washers and explain the important difference between PSI and GPM. By the end, you'll understand how mechanical energy is transformed into hydraulic energy and eventually into that incredibly powerful stream of water. It's a simple machine—but the engineering behind it is surprisingly clever. ⏱️ TIMESTAMPS 00:03 – How Can Water Be This Powerful? 00:59 – A Brief History of Pressure Washers 01:54
