Greenworks GPW2700
Best OverallPros
- Reliable Honda engine starts easily
- Good balance of power and portability
- Solid build quality for the price
Cons
- Hose can be a bit stiff
- No quick-connect nozzle system
The Greenworks GPW2700 is the most popular petrol model in the lineup, and for good reason. It pairs a 2700 PSI axial cam pump with a Honda GCV160 engine, which is known for its reliability and easy starting. Owner reviews consistently praise its ability to clean driveways, patios, and vehicles without bogging down.
The unit sits on a sturdy frame with large wheels, making it easy to move around uneven terrain. While it lacks some premium features like a hose reel, the overall value is strong for homeowners who need dependable power without a high price tag.
Greenworks GPW2000
Best BudgetPros
- Very lightweight and easy to maneuver
- Low price point for a petrol washer
- Simple to maintain
Cons
- Lower PSI limits heavy duty use
- Engine is not as refined as Honda
The GPW2000 is designed for homeowners who need a petrol washer for occasional use. Its 2000 PSI and 1.6 GPM are sufficient for cleaning cars, patio furniture, and small driveways. The lightweight design at 38 lbs makes it one of the easiest petrol washers to transport and store.
Owner reviews note that it starts reliably and is less intimidating for beginners. The main trade-off is the lower power output, which means tougher jobs like stripping paint or cleaning large concrete areas will take longer. It is a solid entry-level option.
Greenworks GPW3000
Best Heavy DutyPros
- Professional-grade CAT pump
- High PSI and GPM for tough jobs
- Honda GX engine is very durable
Cons
- Heavier and bulkier than other models
- Higher price point
The GPW3000 is built for demanding tasks like cleaning large concrete areas, heavy equipment, or stripping paint. It features a CAT triplex plunger pump, which is a step up from the axial pumps found on cheaper models, offering longer life and better performance. The Honda GX200 engine is a commercial-grade workhorse known for its longevity.
Owner reviews highlight its impressive cleaning speed and ability to handle continuous use without overheating. The main downsides are its weight (over 70 lbs) and higher cost. It is best suited for users with frequent, heavy cleaning needs.
Greenworks GPW2500
Best Mid RangePros
- Good power for the price
- Includes a soap tank for detergent
- Decent wheel size for mobility
Cons
- Engine can be louder than Honda models
- Plastic pump housing feels less durable
The GPW2500 sits between the budget and heavy duty models, offering a middle ground for users who need more than 2000 PSI but do not want to pay for a CAT pump. It uses a Greenworks 170cc engine and an axial cam pump, which is adequate for regular home use. The integrated soap tank is a convenient feature for applying detergent.
Owner feedback indicates it handles driveways and fences well, but some note the engine is noisier than the Honda-powered models. The plastic pump housing is a common point of concern for longevity, though most users report good results for several seasons of use.
Greenworks GPW3500
Best Pro UsePros
- Highest PSI and GPM in the lineup
- Commercial grade Honda GX engine
- Professional CAT pump for long life
Cons
- Very heavy at 85 lbs
- Expensive for most homeowners
The GPW3500 is the flagship model in Greenworks petrol lineup, designed for professional use or very demanding home applications. With 3500 PSI and 2.8 GPM, it can clean the toughest grime quickly. The Honda GX270 engine and CAT triplex pump are both commercial-grade components that offer exceptional reliability and service life.
Owner reviews from contractors praise its performance on job sites, noting it can keep up with more expensive brands. The main drawbacks are its weight and price, which put it out of reach for casual users. It is best for those who need a machine that can handle daily heavy use.
What to Check Before Buying a Greenworks Petrol Pressure Washer
PSI (pounds per square inch) and GPM (gallons per minute) are the two key specs. PSI determines cleaning force, while GPM determines cleaning speed. For most home tasks, 2500-3000 PSI with 2.0-2.5 GPM is ideal. Higher numbers mean faster cleaning but also higher cost and weight.
Engine type matters greatly. Honda engines are widely regarded as the most reliable and quietest, while Greenworks own engines offer lower cost but may be louder and less durable. Pump quality also varies: axial pumps are common on budget models, while triplex plunger pumps (like CAT) are more durable and repairable.
Mistakes to Avoid When Choosing a Petrol Pressure Washer
Do not buy based on PSI alone. A high PSI with low GPM will clean slowly, while a balanced unit with moderate PSI and higher GPM often cleans faster. Also, avoid models with plastic pump housings if you plan to use the washer frequently, as they are more prone to cracking.
Do not overlook weight and wheel size. Petrol washers are heavy, and small wheels make them difficult to move across grass or gravel. Look for models with at least 10-inch wheels for better maneuverability. Also, check that replacement parts and service are available for the engine and pump.
