Main trade-off
Westinghouse WPX3400 Gas Pressure Washer
Fuel, oil and exhaust management.
Head-to-head
Westinghouse WPX3400 vs Greenworks 3000: Westinghouse works off-grid, Greenworks avoids fuel and engine care
The short answer
WPX3400 supplies substantially more flow at its rated pressure and works without an electrical outlet. GPW3002A avoids fuel and engine upkeep when a suitable outlet is available.
Before you choose
The reasoning and the trade-offs
The operating-flow difference is more than twofold
WPX3400 lists about 2.36 times the flow at each model's rated pressure point.
What this is based on
2.6 divided by 1.1 is 2.36. The operating pressures also differ, so this is a specification ratio, not a cleaning-speed ratio.

What matters in practice
The differences that matter
The operating-flow difference is more than twofold
WPX3400 lists about 2.36 times the flow at each model's rated pressure point.
How we reached this conclusion
2.6 divided by 1.1 is 2.36. The operating pressures also differ, so this is a specification ratio, not a cleaning-speed ratio.
Ten minutes can mean 26 versus 11 gallons
At the rated points, WPX3400 moves 15 more gallons per ten trigger-on minutes.
How we reached this conclusion
2.6 x 10 = 26 and 1.1 x 10 = 11. Actual consumption depends on trigger use and nozzle.
Gas removes one tether, not every tether
WPX3400 still needs a suitable water supply even without electricity.
How we reached this conclusion
Its engine removes the mains-cord requirement. The pressure washer remains connected to the input hose unless a separately approved supply arrangement is established.
Choice A

Meaningful differences
What changes the fit
| What changes | Westinghouse WPX3400 Gas Pressure Washer | Greenworks 3000 PSI Brushless Electric Pressure Washer | Why it matters |
|---|---|---|---|
| Working output | 3400 PSI at 2.6 GPM | 3000 PSI at 1.1 GPM | The large difference is rated flow, not just the 400 PSI gap. |
| Included tip set | 0, 15, 25 and 40-degree tips plus soap | 15, 25 and 40-degree tips plus soap and turbo | WPX3400 includes a pinpoint tip. Greenworks includes a rotating turbo tip. Both can damage an unsuitable surface. |
| Wheel diameter | 12-inch never-flat wheels | 10-inch never-flat wheels | Larger wheels may help over uneven ground, but neither size guarantees easy handling. |
| Power source | 212cc gasoline engine | Corded brushless electric motor | One needs fuel and outdoor exhaust clearance, the other needs a suitable electrical supply. |
| Between-use care | Engine oil, fuel and gas-engine storage care | No gasoline engine to service | Both still require pump, hose, filter and freeze-protection care. |
| Electrical reach | No mains cord | 35-foot GFCI cord | The gas model removes the outlet-distance constraint, while still depending on a water hose. |
What you give up
Every choice has a cost
If you choose Westinghouse WPX3400 Gas Pressure Washer
- Higher water use at its rated point.
If you choose Greenworks 3000 PSI Brushless Electric Pressure Washer
- Only 1.1 GPM at its 3000 PSI point.
Recommendation switch
The decision flips if...
The accessory requires at least 2.5 GPM at working pressure
Choose Westinghouse WPX3400 Gas Pressure Washer. WPX3400's 2.6 GPM rated point meets that threshold.
Avoiding fuel and engine upkeep is the priority
Choose Greenworks 3000 PSI Brushless Electric Pressure Washer. GPW3002A is corded electric.
You need a fully cordless battery setup
Choose neither. Choose a battery-powered model and verify its working output.
What matters in practice
How to make the call
A long driveway
WPX3400's greater rated flow can better align with higher-flow accessories. Check the surface cleaner's required PSI and GPM together rather than choosing by its diameter or the washer's peak PSI.
A washer used a few times a year
Greenworks avoids fuel and oil tasks that can make occasional gas ownership inconvenient. Winterize and store the electric washer properly too, since removing the engine does not remove freeze risk.
Where the work happens
Map both electricity and water reach. The gas machine belongs outdoors with safe exhaust separation. An electric machine still needs suitable weather-protected power and electrical precautions.
What this comparison cannot tell you
- No work-time savings are predicted from output ratios. Both models require safe nozzle selection and surface testing.
