Greenworks 15-Inch Surface Cleaner (GSC15B)
Best OverallPros
- Wide cleaning path reduces time
- Dual high-pressure nozzles
- Sturdy metal housing
Cons
- Heavier than some competitors
- Not ideal for very small patios
The Greenworks GSC15B is the most popular surface cleaner in the lineup. It features a 15-inch cleaning width that covers ground quickly, and the dual nozzles create a balanced spray pattern that prevents streaking. Owner reviews consistently praise its ability to remove tough grime from concrete and brick without leaving swirl marks.
Build quality is solid with a metal housing that withstands bumps and drops. The 4-year warranty is among the best in the category. It connects to most Greenworks pressure washers with a standard M22 fitting, though some users note it works well with other brands too.
Greenworks 12-Inch Surface Cleaner (GSC12B)
Best BudgetPros
- Lightweight and easy to maneuver
- Affordable price point
- Works with lower PSI washers
Cons
- Smaller cleaning path takes longer
- Plastic housing less durable
The GSC12B is the entry-level Greenworks surface cleaner. Its 12-inch width is best for small patios, walkways, and garage floors. Owner reviews note that it works well with Greenworks 2000-2800 PSI pressure washers, delivering streak-free results on light to medium dirt.
The plastic housing keeps weight down to 7.2 pounds, making it easy to carry and store. However, some users report that the plastic can crack if dropped on concrete. The 4-year warranty covers defects, but it is not as robust as the metal-bodied models.
Greenworks GPW1501 Surface Cleaner
Best for Large AreasPros
- Large cleaning path
- Compatible with most pressure washers
- Good for heavy dirt
Cons
- Shorter warranty than other models
- Heavier build
The GPW1501 is designed for users who need to clean large driveways or commercial patios. It has a 15-inch cleaning width and can handle up to 3000 PSI. Owner reviews highlight its ability to remove algae and mildew quickly without leaving streaks.
The build is heavier at 10.1 pounds, which some users find tiring during extended use. The 2-year warranty is shorter than the standard 4-year coverage on other Greenworks models. It uses a universal M22 connection, so it works with most pressure washers on the market.
Greenworks 18-Inch Surface Cleaner (GSC18B)
Best Heavy DutyPros
- Fastest cleaning path
- High PSI rating
- Durable metal construction
Cons
- Heavy and bulky
- Requires high-flow pressure washer
The GSC18B is the largest surface cleaner in the Greenworks range. With an 18-inch cleaning width and support for up to 3400 PSI, it can clean large concrete areas in a fraction of the time. Owner reviews note that it leaves a consistent finish on driveways and sidewalks.
The weight of 12.3 pounds makes it less portable, and it requires a pressure washer with at least 2.5 GPM to perform properly. The metal housing and 4-year warranty give confidence in its longevity for frequent use.
Greenworks GPW1201 Surface Cleaner
Best CompactPros
- Very lightweight
- Easy to store
- Good for light cleaning
Cons
- Not for heavy grime
- Shorter warranty
The GPW1201 is the most compact Greenworks surface cleaner. It weighs only 6.8 pounds and has a 12-inch cleaning width. Owner reviews say it is ideal for small patios, steps, and garage floors. It works best with pressure washers up to 2600 PSI.
The plastic housing keeps weight down but feels less durable than metal models. The 2-year warranty is adequate for occasional use. It is a good choice for homeowners who need a lightweight tool for light-duty cleaning tasks.
What to check before buying a Greenworks surface cleaner
Before choosing a surface cleaner, check the PSI and GPM of your pressure washer. Greenworks surface cleaners are rated for specific pressure ranges. Using a cleaner with too low PSI will result in poor cleaning, while too high PSI can damage the unit.
Consider the cleaning width. A 15-inch model covers 25% more area per pass than a 12-inch model. For large driveways, a wider cleaner saves significant time. For small patios, a 12-inch model is more maneuverable.
Check the connection type. Most Greenworks surface cleaners use a standard M22 fitting. If your pressure washer has a different connection, you may need an adapter. The weight and build material also matter: metal housings last longer but are heavier.
Mistakes to avoid when using a surface cleaner
One common mistake is using a surface cleaner on a pressure washer with insufficient flow. If your pressure washer has less than 2.0 GPM, the cleaner may not spin properly, leading to uneven cleaning. Always match the cleaner to your washer's specs.
Another mistake is not moving the cleaner in a steady, overlapping pattern. Stopping or moving too slowly can leave swirl marks on concrete. Keep a consistent pace and overlap each pass by about 50% for best results.
Do not use a surface cleaner on delicate surfaces like wood decking unless the manufacturer explicitly states it is safe. The high-pressure spray can damage soft materials. Stick to concrete, brick, and stone.

Greenworks surface cleaners are designed for pressure washers between 2000 and 3400 PSI. Using a lower PSI washer may result in poor cleaning performance.

How do I clean a Greenworks surface cleaner after use?
Rinse the cleaner with clean water to remove debris. Dry it thoroughly before storing to prevent rust or mold buildup.
Is a wider surface cleaner always better?
