The catch
Greenworks 3000 PSI Brushless Electric Pressure Washer
The 3000 PSI and 2.0 GPM on the headline never happen together. Greenworks specifies 1.1 GPM at 3000 PSI and 2.0 GPM at 100 PSI.
Side by side
Greenworks 3000 vs 2700 pressure washers compared: 3000 brings more pressure for hard surfaces, 2700 more rinsing flow
Quick verdict
If stubborn concrete and masonry top your list, the GPW3002A fits best. If decks, vehicles and wide rinsing dominate, the GPW2702A pays off with its better flow at both its rated point and low pressure.
Before you buy
Why, and what it costs you
Only 1.85% separates the rated outputs
At its rated point the GPW3002A produces 3,300 cleaning units and the GPW2702A produces 3,240, which leaves just a 60-unit gap.
Where this comes from
Here a cleaning unit is PSI multiplied by GPM at the same rated point. The comparison is 3,000 × 1.1 against 2,700 × 1.2.
The catch
Greenworks 2700 PSI Brushless Electric Pressure Washer
Its 2.3 GPM peak figure is taken at 100 PSI. Greenworks specifies 1.2 GPM at the 2700 PSI rated point.
Greenworks 3000 PSI Brushless Electric Pressure Washer
- Why pick it
- Concrete and masonry come first.
- Hard-surface grime keeps coming back, so the higher rated pressure earns its keep.
- The catch
- The 3000 PSI and 2.0 GPM on the headline never happen together. Greenworks specifies 1.1 GPM at 3000 PSI and 2.0 GPM at 100 PSI.
Greenworks 2700 PSI Brushless Electric Pressure Washer
- Why pick it
- You mostly do decks, siding and rinsing.
- Extra water flow counts for more to you than the final 300 PSI.
- The catch
- Its 2.3 GPM peak figure is taken at 100 PSI. Greenworks specifies 1.2 GPM at the 2700 PSI rated point.

What this page compares
Two high-output corded Greenworks models, weighed on rated pressure, flow, cleaning units and the work each does best.
The model names imply a big power gap, but at their rated operating points the actual cleaning-unit difference is under 2%.
Which one fits
Pick the situations that sound like you
Tough concrete and masonry
At the rated high-pressure point, the GPW3002A holds an 11.1% pressure advantage.

In practice
Differences you will notice
Only 1.85% separates the rated outputs
At its rated point the GPW3002A produces 3,300 cleaning units and the GPW2702A produces 3,240, which leaves just a 60-unit gap.
How we worked this out
Here a cleaning unit is PSI multiplied by GPM at the same rated point. The comparison is 3,000 × 1.1 against 2,700 × 1.2.
The 2700 gives up pressure and gets flow
Rated pressure is 11.1% higher on the GPW3002A, and rated flow is 9.1% higher on the GPW2702A.
How we worked this out
At the stated rated high-pressure points, the comparisons are 3,000 against 2,700 PSI and 1.2 against 1.1 GPM.
Rinse flow is 15% higher on the 2700
The GPW3002A moves 2.0 GPM and the GPW2702A moves 2.3 GPM at the published 100 PSI point.
How we worked this out
It works out as 2.3 divided by 2.0, minus one. The comparison never pairs maximum pressure with maximum flow.
Over thirty minutes the flow gap becomes concrete
In 30 minutes at 100 PSI, the 3000 moves about 60 gallons and the 2700 moves about 69 gallons, a nine-gallon difference.
How we worked this out
To get gallons, multiply the published GPM at that operating point by 30 minutes.
Never multiply the two headline maxima together
Neither washer reaches its maximum PSI and its maximum GPM at once, so a 6,000 or 6,210 CU headline calculation would compare operating points that do not exist.
How we worked this out
For both exact models, Greenworks publishes a high-pressure flow point and a separate 100 PSI flow point.

Spec by spec
Where they really differ
| Spec | Greenworks 3000 PSI Brushless Electric Pressure Washer | Greenworks 2700 PSI Brushless Electric Pressure Washer | In practice |
|---|---|---|---|
| Rated high-pressure point | 3,000 PSI at 1.1 GPM | 2,700 PSI at 1.2 GPM | At the same rated comparison point, the 3000 brings more pressure and the 2700 moves more water. |
| Rated cleaning units | 3,300 CU | 3,240 CU | Model names suggest much more, yet the practical rated-output gap is only 1.85%. |
| Maximum low-pressure flow | 2.0 GPM at 100 PSI | 2.3 GPM at 100 PSI | At the published low-pressure point, the 2700 moves 15% more rinse water. |
| Motor listing | 14A smart-sensing brushless | 14A in key specifications and 15A in the secondary table | Because Greenworks publishes conflicting amperage for the 2700, motor amperage should not settle this pair. |
| Pump protection | Thermal relief valve | Thermal relief valve | Ownership gives neither model an edge here. |
| Pressure hose | 25 ft kink-resistant | 25 ft kink-resistant | Before a garden hose is added, the working radius is the same for both. |
| Power cord | 35 ft with GFCI | 35 ft with GFCI | The listed outlet reach and ground-fault protection are identical on both. |
| Spray tips | 15°, 25°, 40°, soap and turbo | 15°, 25°, 40°, soap and turbo | The choice does not hinge on shopping for extra nozzles. |
| Accessory fittings | 1/4-inch quick connect and M22 14 mm | 1/4-inch quick connect and M22 14 mm | With standard fittings, common nozzles and suitable surface cleaners remain options. |
| Frame | Folding open steel frame with 10-inch wheels | Folding wheelbarrow steel frame with 10-inch wheels | Each is a full-size wheeled electric that stores upright. |
| Soap system | One-gallon onboard tank | One-gallon onboard tank | These exact models cannot be told apart by soap capacity. |
| Warranty | 10-year motor and 3-year tool | 10-year motor and 3-year tool | These exact models are not distinguished by warranty length. |
Trade-offs
What each pick costs you
With Greenworks 3000 PSI Brushless Electric Pressure Washer
- Compared with compact suitcase-style electrics it is bulkier and heavier. Its edge on hard surfaces also falls short of the sustained flow the leading gas models deliver.
With Greenworks 2700 PSI Brushless Electric Pressure Washer
- As a full-size wheeled electric, it is harder to carry up steps or squeeze onto a crowded shelf than a compact model built for carrying.
Change of plan
When the answer changes
The main job is removing stains from hard surfaces over and over.
Go with Greenworks 3000 PSI Brushless Electric Pressure Washer. For concrete, brick and masonry, the GPW3002A has the higher rated pressure.
The work is mostly vehicles, wood, siding and broad rinsing.
Go with Greenworks 2700 PSI Brushless Electric Pressure Washer. In exchange for more water flow, the GPW2702A gives up some pressure.
The job is commercial duty, over and over.
Neither model fits. The exact manuals for both specify residential use. Step up to a serviceable professional platform.
By the numbers
What the data shows
What we found across the pressure washers we compare, plus the checked facts behind each finding.
How many fit
None of the 28 models checked meets all of “Simple plug-in use suits me”, “I want strong pressure for cutting stains”, “Quick rinsing is my priority”, and “A surface cleaner is part of my plan”, so the pick goes to the closest practical compromise.
