Greenworks is one of the popular brands in the electric pressure washer market. The company offers several electric cleaning tools that produce no direct exhaust emissions during operation. Unlike gas-powered pressure washers, its electric models are generally quieter and require less maintenance. Read this Greenworks 1600 PSI pressure washer review to learn more about its features, cleaning performance, advantages, and limitations.
In this review, we’re going to look at the Greenworks GPW1604 1600 PSI pressure washer. This compact electric unit is suitable for light-duty residential cleaning jobs, including washing outdoor furniture, vehicles, patios, and small walkways. It features a 13-amp universal motor that generates up to 1600 PSI and delivers 1.2 GPM of water flow. Its compact design also makes it easier to transport and store than many larger pressure washers designed for demanding cleaning tasks.
The GPW1604 is an older Greenworks model, so availability, accessories, and warranty terms should be checked before purchasing in 2026. The following review focuses on the GPW1604 rather than other Greenworks 1600 PSI models that may have different features.

Greenworks 1600 PSI Pressure Washer Reviews 2026
Construction
The Greenworks 1600 PSI pressure washer has a compact design that makes it suitable for homeowners with limited storage space. Its lightweight housing is made primarily from durable plastic components, which help keep the overall weight manageable.
The GPW1604 has a practical residential design with a handle for convenient transportation. Its compact construction makes moving the machine around the yard relatively easy.
However, plastic components are more vulnerable to damage from strong impacts than heavy-duty metal frames. Therefore, you should avoid dropping the pressure washer or dragging it by the power cord or high-pressure hose.
If you want another compact electric option, the Greenworks 1700 PSI pressure washer is worth comparing. It provides slightly higher maximum pressure and has a different design.
Powerful 13-Amp Universal Motor
Another important feature of this pressure washer is its 13-amp universal motor. The motor operates using standard 120V AC household electricity and generates up to 1600 PSI of water pressure with a flow rate of 1.2 GPM.
Multiplying the PSI by the GPM gives 1920 cleaning units. This figure provides a basic comparison of pressure and water flow, although it does not fully measure actual cleaning performance.
For everyday tasks such as washing patio furniture, removing loose dirt from sidewalks, and cleaning vehicles, this machine provides enough power when used correctly.
However, it is not the best choice for heavy-duty cleaning, such as removing deeply embedded stains from large concrete areas. If you need more pressure, consider the Greenworks 2000 PSI electric pressure washer.
Compact and Lightweight
Not everyone has enough space to store a large pressure washer. If you have a small garage or storage area, the compact Greenworks GPW1604 can be a convenient choice.
Weighing approximately 18.6 pounds, it is light enough for many homeowners to lift and carry without much difficulty. Its relatively small size also makes it practical for occasional outdoor cleaning.
Compared with large gas-powered units, it takes up less storage space and doesn’t require separate gasoline storage.
Convenient Carrying Handle
The Greenworks GPW1604 includes a handle that makes lifting and transporting the pressure washer easier.
This is particularly useful when moving the machine between your driveway, patio, and backyard. Instead of lifting a heavy steel-framed pressure washer, you can carry this compact electric model to the next cleaning area.
Always switch off and unplug the machine before moving it. Also, avoid carrying the washer by its electrical cord, spray gun, or high-pressure hose.
Check Price on AmazonQuick-Connect Nozzles
The Greenworks 1600 PSI pressure washer is designed to handle different light-duty cleaning tasks. The GPW1604 manual identifies 25° and 40° fan spray tips, along with its detergent application system.
- 25° nozzle: Produces a narrower spray for removing dirt from suitable hard surfaces.
- 40° nozzle: Provides a wider spray for general cleaning and surfaces that require a gentler approach.
- Soap application: Allows compatible pressure-washer detergent to be applied at low pressure.
The 40° nozzle is generally the better starting point for delicate cleaning tasks. However, even a wide spray can damage painted surfaces or soft wood if held too close.
Always begin at a safe distance and test an inconspicuous area before cleaning the entire surface.

High-Pressure Hose and GFCI-Protected Power Cord
The Greenworks GPW1604 comes with a high-pressure hose and an electrical cord designed for residential operation. The GFCI protection helps reduce the risk of electric shock if certain electrical faults occur.
Having a suitable hose length makes cleaning vehicles, walkways, and patios more convenient. However, the actual included hose length should be checked against the package contents because Greenworks has sold several similar 1600 PSI models.
Before starting the machine, inspect the hose for cracks, leaks, and damaged fittings. Never attempt to repair a damaged high-pressure hose with ordinary tape.
Use a properly grounded electrical outlet and keep electrical connections away from standing water. Follow the manufacturer’s instructions before using an extension cord.
Hose and Accessory Storage
Storing the hose properly is important because sharp bends and repeated kinking can shorten its lifespan.
The original article described an onboard hose reel, but this should not be assumed for the GPW1604. Some Greenworks pressure washer models include hose reels, while others use simple holders or storage hooks.
Check your exact machine before purchasing accessories. When storing the unit, coil the hose loosely and keep the spray tips in a safe place.
A separate garden hose reel can help organize the water supply hose, but it should not be used to store a high-pressure hose unless specifically rated for that purpose.
Warranty
Greenworks provides limited warranty coverage on eligible pressure washers. However, warranty periods differ by model, product category, and purchase conditions.
Some Greenworks electric pressure washers are advertised with a three-year limited tool warranty. That does not automatically establish the warranty period for every older GPW1604 unit.
If you’re purchasing this model in 2026, confirm the applicable warranty with the seller or Greenworks. Keep your proof of purchase and check whether replacement parts remain available.
Greenworks 1600 PSI Pressure Washer Troubleshooting Guide
Like other electric pressure washers, the GPW1604 may occasionally develop issues involving power, water supply, or detergent application. Most basic problems can be checked without disassembling the machine.
| Problem | Possible Cause | Solution |

| Pressure washer won’t start | No power, tripped GFCI, or incorrect switch position | Check the outlet and power cord. Reset the GFCI according to the manual and verify the power switch is on. |
| Low water pressure | Clogged nozzle, restricted inlet filter, or insufficient water supply | Check the water supply. Turn off, unplug, and depressurize the unit before cleaning the nozzle or filter. |
| Pressure fluctuates | Air trapped in the pump or restricted water flow | With the motor off and water connected, squeeze the trigger to purge trapped air until the water flows steadily. |
| Water leaks from connection | Loose fitting or damaged O-ring | Depressurize the washer and inspect the connection. Replace damaged seals or fittings. |
| Motor stops unexpectedly | Electrical interruption, overheating, or faulty connection | Switch off and unplug the washer. Allow it to cool and inspect the power supply before restarting. |
| Soap doesn’t dispense | Incorrect spray setting, clogged detergent system, or thick detergent | Use the appropriate low-pressure soap setting and inspect the detergent tank and passages. |

Greenworks 1600 vs 1800 PSI Pressure Washer Comparison
The Greenworks 1600 PSI and 1800 PSI pressure washers are both designed for household cleaning. However, specifications vary depending on the model number and production version.

Before choosing between them, consider the hose length, included nozzles, price, and availability of replacement parts.
How to Maintain the Greenworks 1600 PSI Electric Pressure Washer
Electric pressure washers require less maintenance than gas-powered machines, but proper care is still important.
- Inspect the water inlet filter: Clean out dirt and debris that could restrict water flow.
- Check the hose: Look for cracks, leaks, or damaged connections before every use.
- Clean the nozzles: Remove blockages using the recommended nozzle cleaning tool after unplugging and depressurizing the unit.
- Use suitable detergent: Choose pressure-washer-compatible cleaning solutions and avoid chemicals prohibited by the manufacturer.
- Prevent freezing: Drain and winterize the unit according to the manual before storing it in cold weather.
- Store it properly: Keep the washer dry and protect the electrical cord from sharp bends or damage.
Never run the pressure washer without enough water. Operating the pump dry can damage internal components.
Why Buy the Greenworks 1600 PSI Electric Pressure Washer?
Generating up to 1600 PSI and 1.2 GPM, the Greenworks GPW1604 provides enough cleaning power for many ordinary household tasks. It is especially useful for homeowners who want a compact machine for cleaning cars, patio furniture, fencing, and smaller outdoor surfaces.
The electric motor makes it more convenient than a gasoline-powered machine for occasional use. You don’t need to store fuel, change engine oil, or deal with exhaust fumes.
However, this model is not ideal for stripping paint, removing heavily embedded concrete stains, or cleaning large commercial areas. Such jobs generally require more specialized equipment.
Conclusion
The Greenworks GPW1604 1600 PSI pressure washer is a compact and practical electric unit for light-duty residential cleaning. Its 13-amp motor, 1600 PSI pressure rating, and 1.2 GPM water flow make it suitable for routine outdoor maintenance.
It is easy to transport and store, and its electric operation avoids the fuel-related maintenance required by gas pressure washers. It is also generally quieter than gasoline-powered cleaning equipment.
However, its cleaning power is limited when dealing with tough stains or large concrete areas. Plastic components also require careful handling.
Overall, the Greenworks 1600 PSI pressure washer remains a useful option for basic home cleaning. If you’re buying one in 2026, check the exact model number, included accessories, warranty terms, and seller availability before making your decision.
Frequently Asked Questions
Is it normal for the Greenworks 1600 PSI pressure washer motor to turn off and on?
Yes, when the washer is equipped with an automatic stop system, the motor may stop after you release the trigger and restart when you squeeze it again. This is normal operation. However, frequent cycling while the trigger remains released or pressure is leaking may indicate a problem with the connections, seals, or pressure-control system.
Does the Greenworks GPW1604 have an onboard hose reel?
Do not assume that the GPW1604 includes a built-in hose reel. Greenworks has sold several similar pressure washers with different storage arrangements. Check the exact product photographs and manual before ordering. A hose can usually be coiled separately for storage if no reel is provided.
What is the difference between the GPW1604 and GPW1952?
The GPW1604 has a 1600 PSI maximum pressure rating and 1.2 GPM water flow. The GPW1952 belongs to a different Greenworks pressure washer configuration with higher advertised pressure. Other differences may include wheels, detergent equipment, and supplied accessories. Compare the exact product manuals to confirm the specifications before purchasing.
Can I use the Greenworks 1600 PSI pressure washer to clean my car?
Yes. Use a wide-angle nozzle, maintain a safe distance, and avoid spraying directly at damaged paint, sensitive seals, electrical connectors, or vulnerable components. Test the spray on an inconspicuous area first.
Can I use hot water with the Greenworks GPW1604?
No. The GPW1604 is designed for cold-water use, with a maximum inlet temperature of 104°F (40°C). Using hotter water may damage seals and pump components.
Is the Greenworks 1600 PSI pressure washer worth buying in 2026?
It can still be a reasonable purchase if the machine is in good condition, reasonably priced, and suitable for your cleaning needs. However, compare it with newer Greenworks electric pressure washers and verify replacement-part availability before buying an older model.
