The Westinghouse ePX3500 electric pressure washer is a compact yet powerful cleaning tool designed for homeowners who need to tackle tough grime on driveways, patios, fences, cars, and more. With 2500 max PSI and 1.76 max GPM (at lowest pressure), it provides enough force to blast away mildew, grease, oil, mud, and rust from a variety of surfaces.
Standout features include the anti-tipping technology with a low center of gravity and four-wheel steering, which makes the unit remarkably stable and easy to maneuver around obstacles. The 25 foot easy-coil hose and pro-style steel wand with five quick-connect nozzles (0, 15, 25, turbo, and soap applicator) offer versatility for different cleaning tasks. The onboard 20 ounce soap tank allows for convenient detergent application without needing a separate bucket.
Design and build quality are impressive for the price. The unit is lightweight at 19 pounds and compact at 16.5 inches tall, making storage simple. The four quick-lock wheels provide 360 degree turning, so the washer follows you smoothly from driveway to grass. The Total Stop System automatically shuts off the pump when the trigger is not engaged, conserving energy and extending pump life.
Some drawbacks to consider: the electric cord limits range to the nearest outlet, and the maximum PSI is achieved only at the lowest pressure setting (rated output is 2000 PSI). The soap tank is small at 20 ounces, which may require refills for large areas. However, these are minor trade offs for the convenience and power this unit offers.
Overall, the Westinghouse ePX3500 is an excellent choice for homeowners seeking a reliable, easy to use electric pressure washer. Its combination of power, portability, and thoughtful features like anti-tipping and a long hose make it a top performer in its category. Backed by a 3 year warranty, it delivers great value for everyday cleaning needs.

Buying Guide: What to Look for in a Simpson Pressure Washer
Pressure and Flow: PSI and GPM
PSI (pounds per square inch) measures cleaning power, while GPM (gallons per minute) indicates water flow. For most residential tasks like washing cars, patios, and siding, a machine in the 3000–3500 PSI range with 2.5 GPM works well. Simpson offers models like the SIMPSON Cleaning PS3228 PowerShot 3300 PSI Gas that deliver this balance. For heavy-duty stripping or commercial use, step up to 4000+ PSI and 4.0 GPM, such as the Gas Power Washer For Professionals. CAT Triplex.
Pump Type: Axial vs. Triplex
The pump is the heart of a pressure washer. Axial cam pumps are common on homeowner models; they are lightweight and affordable but not designed for continuous heavy use. Triplex plunger pumps, found on professional-grade Simpsons, offer longer life, higher efficiency, and easier maintenance. If you plan to use the washer frequently or for extended periods, invest in a triplex pump. Our zero turn mower buying guide shares similar thinking about durability for frequent use.
Engine Quality: Honda and Beyond
Simpson pressure washers often pair with Honda engines, known for reliable starts and long service life. The PS3228 uses a Honda GX200, while the top-tier ALH4240 runs a Honda GX390. Both engines are easy to maintain and hold up well under load. For occasional use, a Simpson with a smaller engine may suffice, but for regular jobs, the Honda power is worth the investment. Compare this to engine choices in mowers, as discussed in fabricated vs stamped mower deck.
Accessories and Attachments
A pressure washer is only as good as its accessories. Simpson offers a range of add-ons that enhance cleaning speed and convenience. A SIMPSONAdjustable Spray Patterns And Foam cannon applies thick soap for vehicle washing. The Rated 2000-4000 PSI, Rotating Jets Deliver 10X surface cleaner cuts driveway cleaning time in half. And a turbo nozzle like the Powerful Oscillating Jet Cleans Up To 50% Faster adds rotating power for tough stains. Don’t forget winter protection with SIMPSONProtect Your Pressure Washer Pump From pump guard. For more on property maintenance, see our Property Equipment page.

For homeowners who want a reliable machine that handles everything from driveways to decks, the SIMPSON Cleaning PS3228 PowerShot 3300 PSI Gas offers excellent value with a proven Honda engine. If you need professional-grade power for daily use or large surfaces, the Gas Power Washer For Professionals. CAT Triplex delivers unmatched durability and cleaning speed.

Frequently Asked Questions
What PSI is best for a Simpson pressure washer?
For most residential tasks, 3000–3500 PSI is ideal. Simpson’s PS3228 at 3300 PSI handles cars, fences, and patios well. For heavy stripping, look for 4000 PSI models like the ALH4240.
How do I winterize my Simpson pressure washer?
Use a pump guard like the SIMPSONProtect Your Pressure Washer Pump From to prevent freeze damage. Run the washer with the guard mixed into the water until it exits the nozzle, then store indoors. This protects seals and pistons down to -25°F.
