Head-to-head

Westinghouse WPX3400 vs Simpson PS3228: Westinghouse carries lighter, Simpson emphasizes pump serviceability

The short answer

WPX3400 offers slightly higher rated output in a lighter frame. PS3228 puts more emphasis on its Honda engine, AAA triplex pump and component-specific commercial warranties.

Before you choose

The reasoning and the trade-offs

The headline output gap is modest

WPX3400 adds about 3 percent pressure and 4 percent flow.

What this is based on

100 divided by 3300 is 3.0 percent. 0.1 divided by 2.5 is 4 percent. These figures do not establish a measurable completion-time difference.

What matters in practice

The differences that matter

The headline output gap is modest

WPX3400 adds about 3 percent pressure and 4 percent flow.

How we reached this conclusion

100 divided by 3300 is 3.0 percent. 0.1 divided by 2.5 is 4 percent. These figures do not establish a measurable completion-time difference.

The lighter unit saves 14 lb at each lift

WPX3400 is about 18 percent lighter than PS3228.

How we reached this conclusion

77 - 63 = 14 lb, and 14 divided by 77 is 18.2 percent. Fuel, accessories and water add to transport load.

Paid work makes warranty scope relevant

Simpson's component-specific commercial cover is more meaningful than a single headline warranty length.

How we reached this conclusion

Simpson lists different engine, pump and frame terms. Westinghouse lists one-year limited commercial coverage. Exclusions and proof-of-maintenance conditions still apply.

What you give up

Every choice has a cost

If you choose Westinghouse WPX3400 Gas Pressure Washer

  • Shorter published commercial coverage.

If you choose Simpson PowerShot 3300 PSI Gas Pressure Washer

  • Pneumatic tires require inflation checks.

Recommendation switch

The decision flips if...

A triplex pump and commercial component coverage become mandatory

Choose Simpson PowerShot 3300 PSI Gas Pressure Washer. PS3228 documents both.

A sub-70 lb dry lifting limit becomes mandatory

Choose Westinghouse WPX3400 Gas Pressure Washer. WPX3400 is 63 lb.

The washer must be eligible for sale in California

Choose neither. Find an explicitly eligible model and suffix.

What matters in practice

How to make the call

01

Large homeowner projects

Both provide gas-level flow and pressure for outdoor surfaces. WPX3400's smaller carrying burden can matter if the washer travels in a car or crosses steps between jobs.

02

Frequent or paid cleaning

PS3228's triplex pump, Honda engine and specified commercial component terms give you concrete items to compare with a service provider. They are stronger evidence than a generic claim that one machine will last longer.

03

Terrain and eligibility

Choose tires around the route to the work area. Also check state eligibility: the named versions are not the choices for a California purchase. A similar model with a different suffix may have different approval.

Check these before buying

  • Confirm the exact model suffix and state eligibility before purchasing.
  • Read the current engine, pump, frame and accessory warranty documents for your residential or commercial use.

What this comparison cannot tell you

  • Pump architecture and warranty length do not prove real-world lifetime. Neither unit was run in a comparative cleaning test.
