Comparison Summary
The Westinghouse ePX3500 is the most versatile starting point for a homeowner who wants a compact electric washer: it combines a 25-foot hose, onboard detergent tank and five tips in a 19-pound, low-profile design. Its maximum pressure and flow figures describe different operating conditions. For substantial hard-surface work, the Westinghouse WPX3400 offers a listed 3,400 PSI and 2.6 GPM, but brings engine upkeep and a much larger machine. The Greenworks GPW3002A is a strong corded alternative when a clearly stated pressure-and-flow pairing matters: Greenworks specifies 3,000 PSI at 1.1 GPM, while its 2.0 GPM figure applies at 100 PSI. The Simpson CM61083 adds pneumatic tires and low-oil shutdown for gas-powered work, although it is not for sale in California. At the lighter end, the CRAFTSMAN CMEPW1700 favors organized storage, while the Greenworks GPW1804TN supplies a 40° tip for gentler washing. Choose by the surface and the space you have, then check the exact kit contents before ordering.
Buying Guide
Sizing and Capacity
Here, sizing means both the amount of work and the room needed to handle the machine. The 19-pound ePX3500 rolls and stores more easily than the roughly 51-pound GPW3002A, while the carry-handle ePX3100v is convenient when you would rather lift the washer than steer a frame. For extensive pavement or decking, consider water flow as well as pressure: the gas WPX3400 lists 2.6 GPM, compared with 1.1 rated GPM for the corded WPX3000e. Confirm that your outdoor water supply can meet the chosen machine’s inlet requirements in its manual; a pressure figure alone cannot establish suitable coverage.
Feature Tradeoffs
Start with the spray equipment you will use. A wide 40° pattern on the CMEPW1700 or GPW1804TN is a more appropriate starting point for a vehicle than a concentrated 0° or turbo jet. The ePX3500 includes five tip choices and an onboard detergent tank, while the smaller ePX3100v substitutes a detachable foam cannon for tank storage. The SPX3000’s two tanks make sense if you regularly switch between cleaning solutions. An included foam cannon, soap tip and onboard tank are different ways of applying detergent, so check that the specific kit supports your preferred method rather than treating those terms as interchangeable.

Key Specs to Compare
Read each PSI figure with its matching GPM condition. Greenworks specifies 3,000 PSI at 1.1 GPM for the GPW3002A and 2.0 GPM at 100 PSI; those are two operating points, not 3,000 PSI at 2.0 GPM. Westinghouse similarly distinguishes rated output from separate maximums on the ePX3500 and WPX3000e. The SPX3000 needs an extra check: its current listing describes 2,030 PSI as working pressure at 1.2 GPM, while an earlier manufacturer manual describes 2,030 PSI as maximum initial-discharge pressure and gives 1,450 PSI at 1.24 GPM under typical load. Confirm the documentation for the exact revision if that distinction determines your purchase.
Setup and Handling Considerations
Map the route from outlet and faucet to the farthest cleaning spot before choosing an electric machine. The GPW2003 pairs a 35-foot cord with a 25-foot pressure hose; the CMEPW1700 has the same stated cord length but a 20-foot hose. A hose’s reach is not a substitute for locating the washer near a suitable water connection. The Simpson’s 10-inch pneumatic tires are suited to routes over grass or gravel, whereas the WPX3400 uses 12-inch never-flat wheels. For accessories, the WPX3000e lists M22 compatibility, but fittings and accessory pressure ratings still need to match. Verify the exact box contents: the Simpson listing title says five nozzles, while manufacturer documentation lists four.
Maintenance and Longevity
Electric models remove engine fuel and oil from the routine, but their pumps, hoses, fittings and inlet screens still need care. Follow the model manual for clearing blocked tips, draining water and storage where freezing is possible; water left inside can damage equipment. The gas WPX3400 requires engine maintenance, and the Simpson’s low-oil shutdown is a safeguard rather than a replacement for checking oil. Simpson describes its axial-cam pump as maintenance-free and specifies a thermal-relief valve; that does not mean the entire washer needs no attention. Empty or flush detergent equipment as the applicable manual directs, particularly when changing cleaners or putting the machine away.
Reliability Signals
Use model-specific documentation rather than a broad brand promise. Greenworks states a three-year limited tool warranty for the GPW3002A, and Westinghouse lists three-year limited coverage for the ePX3500. Coverage terms and service procedures matter more than the number alone, especially for a gas engine and pump that may have different terms. Published pressure conditions also help: the GPW3002A gives a pressure-and-flow pairing, while separate maximums on some other machines are less directly comparable. For the CM61083, manufacturer documentation identifies an OEM Technologies axial-cam pump despite an alternate pump name in its retail title; verify the model number before ordering parts.
How to Compare Reviews
Filter owner accounts to the exact model, kit and cleaning job. A comment about the Westinghouse WPX3400’s gas engine does not predict how the electric WPX3000e will handle, despite the similar names. For the GPW3002A, check whether a discussion concerns the Gen 2 corded GPW3002A rather than another Greenworks 3,000-PSI variant. For the SPX3000, look for the pressure-rating language and manual revision attached to the unit being discussed. Give particular weight to accounts that identify the surface, nozzle, cleaning duration and any hose or fitting issue; an unexplained claim that a washer is simply powerful offers little help with your own use case.
Common Mistakes
Do not buy a narrow jet for its apparent speed and then use it on paint, soft wood or vulnerable masonry. Begin with a wider pattern and follow the surface maker’s cleaning guidance. Do not multiply two unrelated maximum specifications to compare machines: the GPW3002A’s 2.0 GPM is specified at 100 PSI, not at its 3,000-PSI point. Check regional availability before choosing the Simpson CM61083; its 49-state designation excludes California sales. Finally, distinguish a cold-water residential washer from a hot-water machine, and confirm that a detergent is suitable for both the surface and the washer before filling a tank or foam cannon.
Frequently Asked Questions
Is electric or gas better for my driveway?
For occasional sections and routine dirt, a corded electric such as the GPW3002A may suit the job if its outlet, hose and water supply reach. For extensive or stubborn hard-surface cleaning, the higher listed flow of the gas WPX3400 is a stronger fit, with more weight and engine upkeep.
Can I use these pressure washers on my car?
Several can be used for vehicle cleaning, but choose a wide spray pattern, keep an appropriate distance and follow your vehicle’s finish-care guidance. The CMEPW1700 and GPW1804TN include 40° tips. Avoid treating a 0° or turbo tip as the default car-washing nozzle.
Does 3,000 PSI and 2.0 GPM mean both happen at once?
Not for the Greenworks GPW3002A: its published figures specify 3,000 PSI at 1.1 GPM and 2.0 GPM at 100 PSI. Compare pressure and flow at stated operating conditions instead of pairing separate maximums.
What should I check before adding a surface cleaner or foam cannon?
Match the accessory’s connection, pressure range and flow requirements to the exact washer. The WPX3000e lists M22 accessory compatibility, but an M22 fitting alone does not establish that every attachment is suitable.
Final Recommendation
Choose the Westinghouse ePX3500 for the broadest mix of routine homeowner jobs: its compact rolling design, 25-foot hose, detergent tank and five tips make it adaptable without taking up the space of a large framed washer. If your main task is extensive, stubborn driveway or deck cleaning, choose the gas-powered Westinghouse WPX3400 instead and plan for its added weight and engine upkeep.
