What Key Features Should You Look for in a Budget Pressure Washer?
When searching for the best cheap pressure washer, consider the following key features:
- PSI (Pounds per Square Inch): The PSI rating indicates the pressure output of the washer, which determines its cleaning power. A higher PSI is suitable for tougher cleaning tasks, such as removing grime from driveways or decks, while a lower PSI is adequate for lighter tasks like washing cars or patio furniture.
- GPM (Gallons per Minute): This metric measures the water flow rate of the pressure washer. A higher GPM means more water is expelled, resulting in faster cleaning. When combined with PSI, GPM gives a better indication of the washer’s overall cleaning efficiency.
- Motor Type: Budget pressure washers typically feature either electric or gas motors. Electric models are quieter, easier to use, and require less maintenance, making them ideal for home use, while gas models often deliver higher power and mobility for larger outdoor tasks.
