The catch
Champion 2800 PSI Gas Pressure Washer
A triplex it is not, since it uses an AR axial pump. The roughly 67-pound gas chassis also still calls for fuel, oil and attention when it is put away for the season.
Side by side
Champion 100778 vs Westinghouse WPX3200 compared: Larger outdoor jobs get more rated pressure and flow from Westinghouse
Quick verdict
For a lower-output gas setup on large transport wheels, go with Champion 100778. For jobs that can use more rated pressure and water flow, go with WPX3200.
Before you buy
Why, and what it costs you
Decide where the machine will be placed
100778 comes with 25 feet of pressure hose and WPX3200 with 25 feet. Before any compatible extension is added, the difference is 0 feet.
Where this comes from
Practical reach shrinks with hose routing, obstacles and safe placement, and the included pressure hose length difference = |25 - 25| feet.
The catch
Westinghouse 3200 PSI Gas Pressure Washer
Car and Driver measured about 95 dBA. Its 3000-PSI-class tested output is more aggressive than routine car paint needs.

In practice
Differences you will notice
Decide where the machine will be placed
100778 comes with 25 feet of pressure hose and WPX3200 with 25 feet. Before any compatible extension is added, the difference is 0 feet.
How we worked this out
Practical reach shrinks with hose routing, obstacles and safe placement, and the included pressure hose length difference = |25 - 25| feet.
Tie pressure and flow to their stated conditions
On its stated rating basis, 100778 lists 2800 PSI and 2.1 GPM, and WPX3200 lists 3200 PSI and 2.5 GPM. None of these figures establishes a timed cleaning winner.
How we worked this out
Both 100778 and WPX3200 are manufacturer rated output. Pressure maxima, maximum flow and rated working points are never merged, and no combined cleaning score is calculated.
WPX3200 has about 19% more rated flow along with 14% more pressure
Compared with Champion 100778, flow goes from 2.1 to 2.5 GPM and pressure from 2800 to 3200 PSI.
How we worked this out
These are manufacturer ratings and not timed task results: (3200 / 2800 - 1) × 100 = 14.3% and (2.5 / 2.1 - 1) × 100 = 19.0%.

| Power source | Gas engine | Gas engine | Factor fuel or electrical setup into the decision. |
| Pressure figure | 2800 PSI | 3200 PSI | Before comparing headline numbers, read the rating basis. |
| Published flow | 2.1 GPM | 2.5 GPM | The documented pressure and nozzle conditions determine flow. |
| Rating basis | Manufacturer rated output | Manufacturer rated output | Do not multiply separate maximum figures into a working-output score. |

Trade-offs
What each pick costs you
With Champion 2800 PSI Gas Pressure Washer
- A zero-degree nozzle comes with it, and Consumer Reports advises against pressure washers supplied with that concentrated tip because of the injury risk.
With Westinghouse 3200 PSI Gas Pressure Washer
- The axial-cam pump is maintenance-free, which means it is not built to be serviced the way the Simpson triplex is. Solid wheels also ride harder over uneven ground.
Decision guide
How to decide
Champion 100778 fits a lower-output gas setup with large transport wheels. WPX3200 fits jobs where more rated pressure and water flow pay off.
Champion's output class is below the Westinghouse's
A 196cc engine produces its listed 2800 PSI and 2.1 GPM. The 12-inch wheels can ease moving the unpowered machine, though the heavy body still counts.
Westinghouse offers more of both pressure and flow
Listed ratings for the 212cc WPX3200 are 3200 PSI and 2.5 GPM. Bigger outdoor work can make use of those higher figures, as long as the surface and accessories can handle them.
Both gas engines still come with maintenance
Fuel, oil checks and proper storage apply to both. Run them outdoors as their manuals say, and skip the concentrated zero-degree spray for routine household cleaning.
