Main trade-off
Greenworks 3000 PSI Brushless Electric Pressure Washer
Its headline 3000 PSI and 2.0 GPM are separate operating points: Greenworks specifies 1.1 GPM at 3000 PSI and 2.0 GPM at 100 PSI.
Head-to-head
Greenworks 3000 vs 2700 pressure washer: 3000 favors hard-surface pressure, 2700 provides more rinsing flow
The short answer
Choose the GPW3002A when stubborn concrete and masonry lead the job list. Choose the GPW2702A when decks, vehicles and broad rinsing make its stronger rated and low-pressure flow more useful.
Before you choose
The reasoning and the trade-offs
The rated output gap is only 1.85%
The GPW3002A produces 3,300 cleaning units at its rated point. The GPW2702A produces 3,240, leaving only a 60-unit gap.
What this is based on
Cleaning units here use PSI multiplied by GPM at the same rated point. The calculation is 3,000 × 1.1 versus 2,700 × 1.2.
Main trade-off
Greenworks 2700 PSI Brushless Electric Pressure Washer
The 2.3 GPM maximum is measured at 100 PSI. At its 2700 PSI rated point Greenworks specifies 1.2 GPM.

About this comparison
Compare Greenworks’ two high-output corded models by rated pressure, flow, cleaning units and the jobs each handles best.
The model names suggest a large power gap. At their rated operating points, the actual cleaning-unit difference is under 2%.

What matters in practice
The differences that matter
The rated output gap is only 1.85%
The GPW3002A produces 3,300 cleaning units at its rated point. The GPW2702A produces 3,240, leaving only a 60-unit gap.
How we reached this conclusion
Cleaning units here use PSI multiplied by GPM at the same rated point. The calculation is 3,000 × 1.1 versus 2,700 × 1.2.
The 2700 trades pressure for flow
The GPW3002A has 11.1% more rated pressure. The GPW2702A has 9.1% more rated flow.
How we reached this conclusion
The calculations compare 3,000 with 2,700 PSI and 1.2 with 1.1 GPM at the stated rated high-pressure points.
The 2700 has 15% more rinse flow
At the published 100 PSI point, the GPW2702A moves 2.3 GPM and the GPW3002A moves 2.0 GPM.
How we reached this conclusion
The calculation is 2.3 divided by 2.0 minus one. This comparison does not combine maximum pressure with maximum flow.
Thirty minutes makes the flow gap tangible
At 100 PSI, the 3000 moves about 60 gallons in 30 minutes while the 2700 moves about 69 gallons. That is a nine-gallon difference.
How we reached this conclusion
Gallons equal the published GPM at that operating point multiplied by 30 minutes.
Do not multiply the two headline maxima
Neither washer produces its maximum PSI and maximum GPM at the same time. A 6,000 or 6,210 CU headline calculation would compare fictional operating points.
How we reached this conclusion
Greenworks publishes separate high-pressure and 100 PSI flow points for both exact models.

Meaningful differences
What changes the fit
| What changes | Greenworks 3000 PSI Brushless Electric Pressure Washer | Greenworks 2700 PSI Brushless Electric Pressure Washer | Why it matters |
|---|---|---|---|
| Rated high-pressure point | 3,000 PSI at 1.1 GPM | 2,700 PSI at 1.2 GPM | The 3000 has more pressure while the 2700 moves more water at the same rated comparison point. |
| Rated cleaning units | 3,300 CU | 3,240 CU | The practical rated-output gap is only 1.85%, far less than the model names imply. |
| Maximum low-pressure flow | 2.0 GPM at 100 PSI | 2.3 GPM at 100 PSI | The 2700 moves 15% more rinse water at the published low-pressure point. |
| Motor listing | 14A smart-sensing brushless | 14A in key specifications and 15A in the secondary table | Greenworks publishes conflicting amperage for the 2700, so motor amperage should not decide this pair. |
| Pump protection | Thermal relief valve | Thermal relief valve | Neither model creates an ownership advantage here. |
| Pressure hose | 25 ft kink-resistant | 25 ft kink-resistant | Their working radius is tied before adding a garden hose. |
| Power cord | 35 ft with GFCI | 35 ft with GFCI | Both have the same listed outlet reach and ground-fault protection. |
| Spray tips | 15°, 25°, 40°, soap and turbo | 15°, 25°, 40°, soap and turbo | No extra nozzle shopping is needed to explain the choice. |
| Accessory fittings | 1/4-inch quick connect and M22 14 mm | 1/4-inch quick connect and M22 14 mm | Standard fittings keep common nozzles and suitable surface cleaners in play. |
| Frame | Folding open steel frame with 10-inch wheels | Folding wheelbarrow steel frame with 10-inch wheels | Both are full-size wheeled electrics that can store vertically. |
| Soap system | One-gallon onboard tank | One-gallon onboard tank | Soap capacity does not separate these exact models. |
| Warranty | 10-year motor and 3-year tool | 10-year motor and 3-year tool | Warranty length does not separate these exact models. |
What you give up
Every choice has a cost
If you choose Greenworks 3000 PSI Brushless Electric Pressure Washer
- It is bulkier and heavier than compact suitcase-style electrics, and its hard-surface advantage does not equal the sustained flow of the gas leaders.
If you choose Greenworks 2700 PSI Brushless Electric Pressure Washer
- It is a full-size wheeled electric, so a carry-first compact model is easier to move up steps or fit on a crowded shelf.
Recommendation switch
The decision flips if...
Repeated hard-surface stain removal is the main job.
Choose Greenworks 3000 PSI Brushless Electric Pressure Washer. The GPW3002A keeps the higher rated pressure for concrete, brick and masonry.
Vehicles, wood, siding and broad rinsing dominate.
Choose Greenworks 2700 PSI Brushless Electric Pressure Washer. The GPW2702A gives up some pressure for more water flow.
The work is repeated commercial duty.
Choose neither. Both exact manuals specify residential use. Move to a serviceable professional platform.
