Questions
What is more important on a pressure washer: PSI or GPM?
Both matter together—multiply PSI × GPM to get Cleaning Units (CU). PSI (pounds per square inch) is the stripping force that breaks grime loose, while GPM (gallons per minute) is the water volume that flushes dirt away. For washing cars, you actually want moderate pressure (1,500–2,100 PSI) and higher GPM (1.5–1.76+ GPM) so you don't damage paint.
Why do upright electric pressure washers keep tipping over?
Many older 2-wheel upright carts mount the heavy motor high off the ground and connect the high-pressure hose near the top handle. Every time you tug the hose, leverage pulls the cart onto its face. Choosing a 4-wheel low-center-of-gravity unit (Westinghouse ePX3100), a compact Kärcher K1700, or a flat jobsite cage (DEWALT DWPW2100) solves tipping completely.
Do I need a gas pressure washer or will a 120V electric model clean my driveway?
A 120V electric pressure washer (2,000–2,300 PSI) will clean patios, decks, siding, cars, and small walkways well using a 15° or turbo nozzle. However, if you have a large two-car concrete driveway or want to spin a 15-inch steel surface cleaner (SIMPSON 80165) at full speed, a 3,100 PSI / 2.3 GPM gas washer (SIMPSON MegaShot MS61222-S) finishes the job in less than half the time.
