2.5 GPM vs 2.3 GPM Pressure Washer
Flow rate
The Westinghouse WPX3200 delivers 2.5 GPM, while the Greenworks GPW2702A offers 2.3 GPM. This 0.2 GPM difference affects cleaning speed. Higher flow rinses debris faster from large surfaces like driveways and decks. The Westinghouse provides slightly more water volume per minute. This can reduce overall job time for big areas. The Greenworks maxes out at 2.3 GPM, which is still strong for residential tasks. You should choose based on how much rinsing you need versus pure pressure.
Power source
The Westinghouse uses a gas-powered 212cc engine with recoil start. It requires fuel and oil maintenance. The Greenworks is electric with a brushless motor and push-button start. It needs no gas, oil, or emissions management. The Greenworks starts instantly every time. The Westinghouse offers mobility without cords but needs engine care. You should pick gas for remote sites or heavy daily use. Pick electric for quiet, easy home maintenance and instant operation.
Maximum pressure
The Westinghouse WPX3200 generates 3200 PSI. The Greenworks GPW2702A produces 2700 PSI. The Westinghouse has a 500 PSI advantage. Higher pressure cuts through stubborn grime, mold, and paint more effectively. The Greenworks uses TruBrushless technology to adapt power, but it still sits lower in raw PSI. For tough jobs like stripping decks or cleaning concrete stains, the Westinghouse pressure is superior. The Greenworks is sufficient for general washing.
Nozzle count
The Westinghouse includes five quick-connect nozzles: 0, 15, 25, 40 degrees, and soap. The Greenworks features JETTFLOW technology and includes nozzles, but the specific count is not listed in the provided data. The Westinghouse gives you a complete set for precise spray patterns. You get dedicated settings for soap application and different spray widths. The Greenworks adapts motor power automatically, which may reduce the need for manual nozzle switching. However, the Westinghouse offers more visible options.
Hose length
The Westinghouse WPX3200 comes with a 25-foot abrasion-resistant super-flex hose. The hose length for the Greenworks GPW2702A is not specified in the data. A 25-foot hose provides good reach for most residential tasks without needing an extension. It allows you to move around cars or patios easily. If the Greenworks hose is shorter, you may need an extension cord or hose extender. The Westinghouse provides a known, adequate length for typical home use.
Which Pressure Washer Fits Your Needs
Heavy-duty deck and driveway owners
You need the extra flow and pressure for large, stubborn jobs. The Westinghouse delivers 3200 PSI and 2.5 GPM. Its 212cc gas engine provides consistent power without hose limits. The 25-foot hose and five nozzles cover most exterior cleaning tasks efficiently.
Apartment dwellers with limited storage
You value quiet operation and easy storage. The Greenworks weighs 50.7 pounds, making it lighter than the gas model. Its 23-inch height fits in tight spaces. The push-button start removes recoil hassle. You get 2700 PSI for routine maintenance without fuel odor.
Users wanting low maintenance cleaning
You want to skip oil changes and gas mixing. The brushless motor adapts power automatically. You avoid spark plug checks. The electric start works every time. You get reliable performance for fences and patio furniture with zero exhaust fumes and simple plug-in convenience.
