The catch
Westinghouse WPX3400 Gas Pressure Washer
Managing fuel, oil and exhaust.
Side by side
Westinghouse WPX3400 vs Greenworks 3000: Westinghouse runs off-grid, Greenworks has no fuel or engine care
Quick verdict
At its rated pressure, WPX3400 delivers far more flow, and it runs without an electrical outlet. GPW3002A spares you fuel and engine upkeep when a suitable outlet is available.
Before you buy
Why, and what it costs you
Operating flow differs by more than twofold
At each model's rated pressure point, WPX3400 lists about 2.36 times the flow.
Where this comes from
Because the operating pressures also differ, this is a specification ratio and not a cleaning-speed ratio. 2.6 divided by 1.1 is 2.36.
The catch
Greenworks 3000 PSI Brushless Electric Pressure Washer
Dependence on a mains cord.
Westinghouse WPX3400 Gas Pressure Washer
- Why pick it
- Power is out of reach at your work area, but your water feed is adequate.
- Sustained rated flow is a priority because your hard-surface work is large.
- The catch
- Managing fuel, oil and exhaust.
Greenworks 3000 PSI Brushless Electric Pressure Washer
- Why pick it
- Gasoline, exhaust and engine service are things you want to avoid.
- Suitable outdoor electricity is on hand, and you can accept lower high-pressure flow.
- The catch
- Dependence on a mains cord.

In practice
Differences you will notice
Operating flow differs by more than twofold
At each model's rated pressure point, WPX3400 lists about 2.36 times the flow.
How we worked this out
Because the operating pressures also differ, this is a specification ratio and not a cleaning-speed ratio. 2.6 divided by 1.1 is 2.36.
In ten minutes, 26 versus 11 gallons
Per ten trigger-on minutes at the rated points, WPX3400 moves 15 more gallons.
How we worked this out
Actual consumption depends on trigger use and nozzle. 2.6 x 10 = 26 and 1.1 x 10 = 11.
Gas cuts one tether and leaves the others
Even without electricity, WPX3400 still needs a suitable water supply.
How we worked this out
The engine takes away the need for a mains cord. The pressure washer stays tied to the input hose unless a separately approved supply arrangement is established.
Option A
Westinghouse, WPX3400
WPX3400 Gas Pressure Washer
For larger outdoor jobs, this 212cc gas washer delivers a rated 3400 PSI with 2.6 GPM of flow. It rides on a wheeled frame and has an axial-cam pump.
- Best for
- bigger concrete and driveway jobs outdoors
Facts we checked
- The rating is 3400 PSI and 2.6 GPM.
- An axial-cam pump is driven by a 212cc four-stroke OHV engine.
- It weighs 63 lb dry and rolls on 12-inch never-flat wheels.
- Five quick-connect tips and a 25-foot hose are included.
Option B
Greenworks, GPW3002A Gen 2
3000 PSI Brushless Electric Pressure Washer
Corded and high-output, with a steady wheeled frame and a brushless motor. Its operating pressure is enough for most hard-surface cleaning around a house.
- Best for
- Top all-round pick among electric pressure washers
Facts we checked
- PWMA certified at 3000 PSI and 1.1 GPM, with maximum flow of 2.0 GPM at 100 PSI
- A brushless electric motor, a 25-foot pressure hose and a 35-foot GFCI cord
- Five quick-connect tips in 15°, 25°, 40°, soap and turbo
Spec by spec
Where they really differ
| Spec | Westinghouse WPX3400 Gas Pressure Washer | Greenworks 3000 PSI Brushless Electric Pressure Washer | In practice |
|---|---|---|---|
| Working output | 3400 PSI at 2.6 GPM | 3000 PSI at 1.1 GPM | Rated flow differs a lot, on top of 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 | A pinpoint tip comes with WPX3400 and a rotating turbo tip with Greenworks. Either can damage an unsuitable surface. |
| Wheel diameter | 12-inch never-flat wheels | 10-inch never-flat wheels | Over uneven ground larger wheels may help, yet neither size guarantees easy handling. |
| Power source | 212cc gasoline engine | Corded brushless electric motor | Fuel and outdoor exhaust clearance are needed by one, a suitable electrical supply by the other. |
| Between-use care | Engine oil, fuel and gas-engine storage care | No gasoline engine to service | Pump, hose, filter and freeze-protection care are still required for both. |
| Electrical reach | No mains cord | 35-foot GFCI cord | The gas model gets rid of the outlet-distance constraint but still depends on a water hose. |
Trade-offs
What each pick costs you
With Westinghouse WPX3400 Gas Pressure Washer
- It uses more water at its rated point.
With Greenworks 3000 PSI Brushless Electric Pressure Washer
- Just 1.1 GPM comes at its 3000 PSI point.
Change of plan
When the answer changes
The accessory needs 2.5 GPM or more at working pressure
Go with Westinghouse WPX3400 Gas Pressure Washer. That threshold is met by the 2.6 GPM rated point of WPX3400.
The priority is steering clear of fuel and engine upkeep
Go with Greenworks 3000 PSI Brushless Electric Pressure Washer. Corded electric is what GPW3002A is.
A fully cordless battery setup is what you need
Neither model fits. Pick a battery-powered model and check its working output.
Decision guide
How to decide
WPX3400 gives much more flow at its rated pressure and works with no electrical outlet at all. GPW3002A means no fuel or engine upkeep, provided a suitable outlet is available.
A lengthy driveway
Higher-flow accessories can be a better match for WPX3400's greater rated flow. Look at the surface cleaner's required PSI and GPM together, and do not choose by its diameter or by the washer's peak PSI.
A washer you use only a few times a year
Greenworks skips the fuel and oil chores that can make owning a gas washer for occasional use a nuisance. Still winterize and store the electric washer properly, because taking away the engine does not take away the risk of freezing.
Where you will be working
Work out how far both electricity and water reach. Keep the gas machine outdoors with its exhaust safely separated. An electric machine still needs power that is suitable and protected from the weather, plus electrical precautions.
What this page can’t tell you
- Output ratios do not predict any savings in work time. Either model calls for a safe nozzle choice and testing on the surface.
By the numbers
What the data shows
What we found across the pressure washers we compare, plus the checked facts behind each finding.
How many fit
None of the 28 models checked meets all of “I have long, heavy-duty cleaning to do”, “Simple plug-in use suits me”, “Quick rinsing is my priority”, and “Driveways and concrete are what I clean”, so the pick goes to the closest practical compromise.
