This comparison covers the SIMPSON vs westinghouse pressure washer debate. Both units deliver high-pressure cleaning for home and light professional tasks. You get five nozzles and twenty-five-foot hoses with either choice. The main difference is power. One uses a Honda gas engine for mobility and raw flow. The other relies on a 13-amp electric motor for lighter duty jobs. Your choice depends on where you work and how much water flow you need.

Which one should you choose?
Choose Westinghouse 3200 PSI Electric Pressure Washer if
- You need a lightweight unit for easy storage and transport.
- You prefer electric power for indoor or garage use without exhaust.

- You need a commercial-grade triplex plunger pump for durability.
- You want cordless mobility for driveways or remote job sites.
Verdict: The Westinghouse model suits homeowners who prioritize low weight and electric convenience for patios and cars. The SIMPSON unit is better for those needing higher flow and gas-powered mobility for heavy-duty cleaning. Choose based on your need for portability versus raw cleaning speed.
Westinghouse vs Simpson Pressure Washer
Power source
The Westinghouse WPX3200e relies on a 13A universal electric motor. You plug it in using the included 35-foot power cord. This setup works well near outlets but limits range. The SIMPSON PS3228 uses a Honda GX200 gas engine. It operates independently of electrical grids, offering true mobility for remote sites or large properties. Gas power also means no cord management during heavy-duty jobs. You choose between the convenience of electric or the freedom of gas depending on your workspace.
Pressure output
SIMPSON delivers 3300 PSI maximum pressure. This higher number helps tackle stubborn grime on concrete or stripping paint. Westinghouse offers 3200 max PSI and 2800 rated PSI. While slightly lower on paper, the difference is marginal for most home tasks. Both machines exceed typical residential needs for cars and decks. The SIMPSON holds a slight technical advantage in peak pressure, which matters for tough commercial jobs. Westinghouse remains sufficient for standard cleaning duties around the home.
Flow rate
Flow rate determines how fast you rinse debris away. SIMPSON provides 2.5 GPM. This higher volume cleans faster by washing away dirt rather than just blasting it. Westinghouse offers 1.76 max GPM and 1.1 rated GPM. The lower flow means you might need more time to rinse large areas like driveways. Higher GPM is generally preferred for efficiency. SIMPSON wins this round due to significantly better water volume, which speeds up the overall cleaning process.
Pump type
Pump construction affects longevity and maintenance. SIMPSON features a triplex plunger pump. This design is common in professional-grade machines and handles higher pressures and flows better. Westinghouse uses an axial cam pump. These are standard for electric units and are generally lighter and less expensive. Triplex pumps often last longer under heavy use. The SIMPSON pump type suggests better durability for frequent or intense applications compared to the axial cam design.
Weight and mobility
Westinghouse weighs 33.1 pounds. It is lightweight and easy to lift into a car trunk or move around a small patio. SIMPSON weighs 74.8 pounds. It is significantly heavier due to the gas engine and steel frame. Both have 10-inch wheels. Westinghouse has never-flat wheels, while SIMPSON has pneumatic tires. The lighter Westinghouse is easier to maneuver manually. SIMPSON’s wheels handle rough terrain better, but its weight makes it harder to transport without a cart.
Features and accessories
Westinghouse includes a built-in 0.61-gallon soap tank. This allows you to apply detergent without a separate bottle or siphon tube. SIMPSON does not list an onboard soap tank in its specs. Both include five quick-connect nozzles and 25-foot hoses. Westinghouse adds a 35-foot power cord, giving you more reach for electrical outlets. SIMPSON includes a rear-load gun and 16-inch wand. The onboard soap tank is a unique convenience feature for Westinghouse that simplifies the washing process.
Which Pressure Washer Fits Your Job
Homeowners near power outlets
The Westinghouse WPX3200e uses a 13A universal electric motor. You plug it in with the 35-foot cord. This avoids gas fumes and noise. The 3200 PSI and 1.76 GPM handle decks and cars. The soap tank cleans surfaces without extra gear. It weighs 33.1 pounds for easy storage.
Contractors needing high flow
The SIMPSON PS3228 delivers 2.5 GPM for faster cleaning. Its Honda GX200 engine offers mobility without cords. The 3300 PSI and triplex plunger pump handle tough grime. The 74.8-pound steel frame supports professional use. Five nozzles and a 25-foot hose cover most job sites efficiently.
Users wanting quiet operation
Electric motors run quieter than gas engines. The Westinghouse unit eliminates exhaust and loud engine noise. This matters for residential neighborhoods or early morning chores. The 3200 PSI still cleans effectively. You save time on fuel mixing and engine maintenance.
Those cleaning large areas
Gas power means you are not tied to an outlet. The SIMPSON unit moves freely across large driveways or fences. The 2.5 GPM flow rate removes dirt faster than lower flow models. The Honda engine starts reliably. You can clean anywhere without extension cords.
