Greenworks is best known for battery and corded outdoor tools that skip gas engines entirely, and its greenworks electric pressure washers follow the same idea: plug in, press a button, and clean without oil changes, spark plugs or pull cords. For a first-time homeowner, that simplicity is the big appeal. The harder part is reading the numbers on the box, because every model lists a PSI figure and a GPM figure, and those two numbers decide whether a washer suits a car, a deck or a whole driveway.
The six models below run from 1700 PSI to 3000 PSI, and they differ mainly in pressure, water flow, motor type (the two biggest use a brushless motor) and the accessories in the box, such as nozzles, hose length and soap tanks.
Greenworks Electric Pressure Washers Compared
| Model | Max PSI | GPM | Hose length | Brushless motor |
|---|---|---|---|---|
| Greenworks 3000 PSI (GPW3002A) | 3000 | 2.0 | 25 ft | Yes (TruBrushless) |
| Greenworks 2100 PSI (GPW2101A) | 2100 | 1.2 | 20 ft or 25 ft (listing conflicts) | Not listed |
| Greenworks 2700 PSI (GPW2702A) | 2700 | 2.3 | 25 ft | Yes (TruBrushless) |
| Greenworks 1700 PSI (GPW1705) | 1700 | 1.2 | 20 ft or 25 ft (listing conflicts) | Not listed |
| Greenworks 1800 PSI | 1800 | 1.1 | 20 ft | Not listed |
| Greenworks 2000 PSI (GPW2003) | 2000 | 1.2 | 25 ft | Not listed |
Greenworks 3000 PSI Brushless for Heavy-Duty Cleaning
Greenworks
Greenworks 3000 PSI (2.0 GPM Max) Brushless Electric Pressure Washer
Price and specifications are read from the Amazon product page and can change.
Greenworks 3000 PSI
Best for: Big driveways and heavy grime
Pros
- 3000 PSI, 2.0 GPM
- TruBrushless 14 amp motor
- Metal gun, five nozzles
Cons
- Heavy at 23 kg
- Largest footprint here
The Greenworks 3000 PSI washer (model GPW3002A) is the most powerful model in this lineup by pressure. It uses a 14 amp TruBrushless motor to reach 3000 max PSI and 2.0 GPM, and the listing quotes 3300 “cleaning units”, a figure made by multiplying PSI by GPM that gives a rough sense of overall cleaning power. A brushless motor uses electronics instead of small carbon brushes to spin, which generally means less wear and more efficient power. The listing says the PSI and GPM claims were verified by an independent lab, and it mentions JettFlow technology for up to 50% more flow when rinsing.
The kit is generous: a rugged metal gun, a 25-foot Uberflex kink-resistant hose, and five quick-connect nozzles (turbo, 15, 25 and 40 degree, plus soap), all stored on the wand holder. It has a steel frame with oversized wheels. The listing gives a weight of 23 kg and a maximum inlet water temperature of 104°F.
This suits homeowners with large concrete driveways, boats or stubborn grime. For simple car washes it is more machine than you need, and the 1700 or 1800 PSI models will be easier to store.
Greenworks 2100 PSI for Medium-Duty Jobs
Greenworks
Greenworks 2100 PSI (1.2 GPM) Electric Pressure Washer
Price and specifications are read from the Amazon product page and can change.
Greenworks 2100 PSI
Best for: Fences, siding and patios
Pros
- 2100 PSI, 1.2 GPM
- Telescoping handle
- 35 ft cord with GFCI
Cons
- Hose length listed as 20 and 25 ft
- No 15 degree nozzle listed
The Greenworks 2100 PSI washer (model GPW2101A) delivers 2100 PSI at 1.2 GPM, and the listing aims it at medium-duty work such as fences, decks, concrete patios, siding, sidewalks, patio furniture and small driveways. It starts with a push button, has a 35-foot power cord with a built-in GFCI plug (a safety device that cuts power if it senses a fault) and a telescoping handle that pulls out for transport.
In the box you get a gun, 25 and 40 degree nozzles, a turbo nozzle, a soap applicator and a 1/4 inch universal quick-connect system. The hose length is inconsistent in the listing: the features say 20 feet while the specifications and description say 25 feet. The listed weight of 1.5 pounds is also clearly not the machine’s real weight, so the listing does not reliably specify it. It carries a 3 year limited warranty.
Pick this for a homeowner who wants one step up from light-duty models for decks and siding, without the size of the brushless units. For a large driveway, the 2700 PSI model’s extra flow will save time.
Greenworks 2700 PSI Brushless for the Highest Flow
Greenworks
Greenworks 2700 PSI (2.3 GPM Max) Brushless Electric Pressure Washer
Price and specifications are read from the Amazon product page and can change.
Greenworks 2700 PSI
Best for: Most flow for big rinsing jobs
Pros
- 3 GPM, highest flow here
- TruBrushless motor adapts to nozzle
- Cast aluminum axial cam pump
Cons
- Heavy at 23 kg
- Warranty not stated
The Greenworks 2700 PSI washer (model GPW2702A) has less top pressure than the 3000 PSI model but more water flow: up to 2.3 GPM, the highest figure in this group. The listing explains that flow ranges from 1.2 to 2.3 GPM depending on the nozzle, and the TruBrushless motor automatically adapts its power to whichever nozzle you attach. It also uses a heavy-duty cast aluminum axial cam pump and JettFlow technology.
It comes with the same five quick-connect nozzles (turbo, 15, 25, 40 and soap), an integrated wand holder, oversized wheels and a steel frame, with a 25-foot hose and a listed weight of 23 kg. The listing does not state the warranty length.
This is the choice when rinsing speed matters, such as big decks, siding and long walkways. It gives way to the 3000 PSI model only when you need the extra pressure for the toughest stains.
Greenworks 1700 PSI for Cars and Small Spaces
Greenworks
Greenworks 1700 PSI (1.2 GPM) Electric Pressure Washer
Price and specifications are read from the Amazon product page and can change.
Greenworks 1700 PSI
Best for: Car washing in small spaces
Pros
- Compact body
- 1700 PSI, gentle on cars
- 3 year limited warranty
Cons
- Only two tips, no soap applicator listed
- Hose length conflicts in listing
The Greenworks 1700 PSI washer (model GPW1705) is the gentlest option, with 1700 PSI at 1.2 GPM. The listing calls it great for light-duty residential cleaning of cars, trucks, motorcycles, boats, RVs, patio furniture, windows and decks. It has push-button start, a 35-foot cord with GFCI plug, and one of the most compact bodies here at roughly 9 by 10 by 13 inches.
The accessory list is shorter: a gun, a 25 degree nozzle, a 40 degree nozzle, a tangle-free hose and the 1/4 inch quick-connect system. The features say the hose is 20 feet, while the specifications say 25 feet. It carries a 3 year limited warranty.
This fits a first-time buyer mainly washing a car, bikes and patio chairs, and anyone short on storage space. If you want a turbo nozzle and soap applicator in the box, the 1800 PSI model adds both.
Greenworks 1800 PSI for Light Jobs With Soap
Best for: Light jobs with soap applicator
Pros
- PWMA certified
- Turbo nozzle and soap applicator
- 3 year limited warranty
Cons
- Lowest flow at 1.1 GPM
- Shorter 20 ft hose
The Greenworks 1800 PSI washer is PWMA certified, meaning its ratings follow the Pressure Washer Manufacturers’ Association standard. It delivers 1800 PSI at 1.1 GPM, the lowest flow in this lineup, and is aimed at light-duty residential cleaning. The description adds removing dirt, grime and mildew from driveways, patios, decks, siding and vehicles.
The kit includes a gun, a 40 degree nozzle, a turbo nozzle, a soap applicator and a 20-foot non-marring hose with 1/4 inch quick connect. It has push-button start, a 35-foot cord with GFCI and a 3 year limited warranty. The body is compact, around 11 by 9 by 13 inches.
Choose this for light jobs where soap helps, like washing a car with detergent. It gives way to the 2000 PSI model if you want an on-board soap tank and a longer hose.
Greenworks 2000 PSI With On-Board Soap Tank
Best for: Medium jobs with soap tank
Pros
- On-board soap tank
- Auto start/stop saves pump
- 14 amp motor, 2000 PSI
Cons
- Nozzle set not detailed
- Bulkier open frame
The Greenworks 2000 PSI washer (model GPW2003) is rated to PWMA standards at 2000 PSI and 1.2 GPM, powered by a 14 amp motor. Its standout feature is an on-board soap tank: switch to the soap tip and the washer draws detergent automatically. It also has start/stop technology, which switches the motor off when you release the trigger to save energy and extend pump life.
It has an open-frame design, a 25-foot hose, a listed weight of 12.6 kg and a 3 year warranty. The listing does not specify exactly which nozzles are included beyond the soap tip.
This suits medium-duty jobs like grills, walkways, patio furniture and vehicles for owners who use detergent often. For heavier work on large concrete, step up to one of the brushless models.
How to Choose the Right Greenworks Electric Pressure Washer
Understand PSI vs GPM first. PSI (pounds per square inch) is how hard the water hits; it loosens dirt. GPM (gallons per minute) is how much water flows; it rinses dirt away. High PSI with low GPM cleans small spots well but slowly; more GPM covers big areas faster. The 2700 PSI model has the highest flow, while the 3000 PSI model has the highest pressure.
Match the number to the job. Around 1700 to 1800 PSI suits cars, bikes and patio furniture. Around 2000 to 2100 PSI suits decks, fences and siding. The 2700 and 3000 PSI brushless models are built for driveways, boats and heavy grime. If you want a broader view of brand options, our Greenworks power washer guide covers more of the range.
Check the accessories. The two brushless models include five nozzles. The 1700 PSI includes only two tips, the 1800 PSI adds turbo and soap, and the 2000 PSI has an on-board soap tank.
Think about storage and weight. The 1700 and 1800 PSI units are compact, while the brushless models weigh 23 kg with wheels. If you are weighing corded against fuel-powered machines, our gas pressure washer guide explains that trade-off.
FAQ
Which Greenworks pressure washer should I buy for washing a car
The 1700 PSI or 1800 PSI model. Both are listed for light-duty cleaning of cars and trucks. Use the wider 40 degree nozzle on paint to stay gentle.
What does brushless mean on the 2700 and 3000 PSI models
A brushless motor uses electronic control instead of carbon brushes to spin. In general this reduces wear and improves efficiency. On the 2700 PSI model, the listing says the motor also adapts its power to the nozzle you choose.
Is more PSI always better
No. Too much pressure can damage soft wood, paint or car trim. Pick the pressure your jobs need, and use wider nozzles for delicate surfaces. For big areas, higher GPM often matters more than higher PSI.
Do Greenworks electric pressure washers need maintenance
The 1700, 1800 and 2100 PSI listings say there is no gas, oil, spark plugs, air filters or pull cord to worry about. You should still drain water and store the unit protected from freezing, as with any pressure washer.
Can I use hot water in these washers
The 3000 PSI listing gives a maximum inlet water temperature of 104°F, and the 1800 PSI is described as a cold water washer. The other listings do not specify, so use cold water to be safe. Our electric pressure washer roundup explains more basics for beginners.
