1. Understanding Pressure Washers: How They Work
Before you start shopping for a pressure washer, it’s important to understand how this versatile tool works. A pressure washer uses highly pressurized water to remove dirt, grime, mold, and other debris from surfaces efficiently. The cleaning power of a pressure washer is mainly determined by two factors: PSI (pounds per square inch), which measures the water pressure, and GPM (gallons per minute), which measures the water flow. Higher PSI means more force for tough stains, while higher GPM allows you to clean larger areas faster. Understanding these basics will help you choose a pressure washer that meets your home cleaning needs without causing surface damage.
What Is a Pressure Washer?
A pressure washer is a mechanical device that combines water pressure and flow to clean surfaces more effectively than a standard hose. The PSI indicates the force with which the water hits a surface, while GPM determines how much water is delivered during cleaning. For example, a high-PSI washer can tackle oil stains on a driveway, while a washer with moderate PSI and GPM is better suited for delicate surfaces like wood decks or painted fences. Choosing the right combination ensures that your pressure washer is both efficient and safe for different tasks.
How Pressure Washers Clean Different Surfaces
Not all surfaces require the same level of pressure, and using too much PSI on a delicate surface can cause damage. Pressure washers are versatile enough to clean a wide range of surfaces around your home, including driveways, patios, decks, and fences. Understanding the appropriate pressure and water flow for each type of surface is key to achieving a clean finish without accidents.
Recommended Pressure and Flow for Common Surfaces
| Surface Type | Recommended PSI Range | Recommended GPM | Notes |
|---|---|---|---|
| Driveway | 2500-3500 | 2.5-4 | Heavy-duty cleaning |
