Westinghouse ePX3500 vs Greenworks GPW3002A: Which One Fits Your Cleaning Setup?

For carrying and low-profile storage, the ePX3500 is the clearer fit on the published specifications: Westinghouse lists it at 19 pounds and 16.5 inches tall, with four wheels that steer through 360 degrees. Consider the Greenworks if its 3000-PSI maximum label, upright storage, ten-inch wheels, or one-gallon soap tank is more useful for your setup. Greenworks states that 3000 PSI occurs at 1.1 GPM and that 2.0 GPM is at 100 PSI; these specifications do not establish which machine cleans faster.

The buying question

Should your priority be the ePX3500's compact, light, four-wheel setup or the Greenworks GPW3002A's different published pressure and flow ratings and larger soap reservoir?

The ePX3500 has a manufacturer-listed 19-pound, 16.5-inch-tall body and four 360-degree wheels. Greenworks publishes a 3000-PSI maximum at 1.1 GPM, separately lists 2.0 GPM at 100 PSI, and describes an open-frame washer that stores vertically with a one-gallon soap tank. The rating conditions are not a head-to-head performance test.

Quick verdict

When the recommendation changes
  • If measured cleaning speed or stain removal is the deciding factor, the published specifications do not settle it; seek comparable independent test evidence.
  • If weight or overall dimensions decide the purchase, obtain a current manufacturer specification for the GPW3002A first; the opened exact-model Greenworks page did not list those measurements.

The differences that matter

Pressure And Flow Ratings At Stated Conditions

Westinghouse ePX3500 Electric Pressure Washer

2,500 max PSI and 1.76 max GPM at lowest pressure; 2,000 rated PSI and 1.2 rated GPM.[1]

Greenworks GPW3002A 3000 PSI 2.0 GPM Cold Water Electric Pressure Washer

3,000 max PSI at 1.1 GPM; 2.0 GPM at 100 PSI.[2]

What this changes: Manufacturer-reported rating conditions are not matched measurements; peak figures do not support a cleaning-performance winner.[1, 2]

The available evidence does not establish a winner

Unit Portability And Included Cleaning Setup

Westinghouse ePX3500 Electric Pressure Washer

19 pounds; 16.5 inches high; four quick-lock wheels with 360-degree steering.[1]

Greenworks GPW3002A 3000 PSI 2.0 GPM Cold Water Electric Pressure Washer

Wheelbarrow-style steel frame, 10-inch wheels, and upright storage; weight and overall dimensions not stated on the opened page.[2]

What this changes: Compare the documented form and storage descriptions to your intended storage location and handling needs; no relative weight/footprint claim is made.[1, 2]

The better fit depends on your priorities

Unit Portability And Included Cleaning Setup

Westinghouse ePX3500 Electric Pressure Washer

20-ounce onboard detergent tank; five tips: 0°, 15°, 25°, turbo, soap.[1]

Greenworks GPW3002A 3000 PSI 2.0 GPM Cold Water Electric Pressure Washer

One-gallon onboard soap tank; five tips: 15°, 25°, 40°, soap, turbo.[2]

What this changes: Tank size and supplied tip angles can help the buyer compare included detergent capacity and nozzle choices; follow the manuals for surface-specific use.[1, 2]

The better fit depends on your priorities

Best for your routine

A buyer who needs to carry the washer or fit it into a low storage space

Best fit: Westinghouse ePX3500 Electric Pressure Washer

Based on listed features, not comparative testing.

Westinghouse explicitly lists the ePX3500 at 19 pounds and 16.5 inches tall. Greenworks' opened product page did not provide a comparable weight or overall dimensions, so this recommendation is based on the ePX3500's documented fit rather than a claim that it is lighter or smaller than the GPW3002A.

A buyer who prefers the GPW3002A's published peak-pressure specification, upright storage, or one-gallon onboard soap tank

Best fit: Greenworks GPW3002A 3000 PSI 2.0 GPM Cold Water Electric Pressure Washer

Based on listed features, not comparative testing.

Greenworks documents these characteristics, but the published pressure and flow labels do not establish cleaning speed or surface results against the ePX3500.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

This comparison does not assess current prices or establish a value winner.

Current offers and price history were not assessed in this analysis, so it does not recommend buying now or waiting.

Limitations

  • No controlled side-by-side cleaning, speed, noise, or durability test was conducted or used; specifications do not prove performance superiority.
  • Pressure and flow values are manufacturer claims stated at different operating conditions. Do not multiply unrelated maxima or assume maximum PSI and maximum GPM occur simultaneously.
  • The Greenworks product page does not provide an exact weight or overall dimensions, so this comparison does not say it is heavier or larger than the ePX3500.
  • Current prices and price history were not assessed.
  • The Greenworks page's wheelbarrow frame and upright-storage details are manufacturer descriptions, not an independent handling test.

Questions shoppers ask

Does the Greenworks GPW3002A deliver 3,000 PSI at 2.0 GPM?

Greenworks states 3,000 max PSI at 1.1 GPM and separately says 2.0 GPM at 100 PSI. Treat those as different operating points, not simultaneous maximum output.

Which pressure washer cleans concrete faster?

These manufacturer specifications do not answer that. There is no comparable side-by-side test here, so choose based on the documented setup and rating conditions rather than a speed claim.

Methodology and sources

Compared the manufacturers' stated pressure and flow conditions, product form/storage descriptions, and included soap/nozzle setup. No maxima were multiplied, and no relative cleaning-speed, noise, or reliability result was inferred.
