Greenworks Surface Cleaner for Pressure Washers, 11in Universal Attachment — Quick-Connect, Low-Splash

The Greenworks 11" Surface Cleaner is a universal pressure-washer attachment that delivers faster, streak-free cleaning of patios, driveways, decks, and sidewalks without constant wand-swiveling.

Swap the back-and-forth of a wand for a rotating, enclosed head built to reduce splash and speed up large flat-surface jobs. This quick-connect accessory fits Greenworks pressure washers and many other common threaded units, transforming concentrated spray into a wide, consistent cleaning path so you spend less time and effort removing dirt, mildew, oil marks, and grime.

How does the 11" surface cleaner speed up outdoor cleaning?

Instead of covering a surface with narrow, repeated passes from a nozzle, the cleaner’s twin rotating jets deliver an even, broad swath that removes grime in one pass. Its enclosed housing prevents overspray and channels pressure where you need it most, cutting overall job time and water use.

• 11-inch cleaning diameter covers more area per pass than a single nozzle.
• Dual rotating arms provide uniform contact with the surface.
• Enclosed skirt reduces splash, keeping you and surroundings drier.
• Quick-connect coupling attaches in seconds to compatible pressure washers.

Will this Greenworks attachment fit my current pressure washer?

The tool is designed for compatibility with Greenworks pressure washers and many standard-thread models. Check your machine’s wand or adapter threads and pressure rating to confirm a safe match before attaching.

• Quick-connect system for Greenworks units and common adapters.
• Works within typical residential pressure washer PSI ranges—verify manufacturer specs.
• Lightweight design keeps the wand manageable for extended jobs.
• No special tools needed to install or remove the attachment.

What surfaces and stains is the surface cleaner best suited for?

Its rotating jets and wide head work well on flat, hard surfaces where consistent pressure is needed for thorough cleaning. Use it on concrete, pavers, sealed decks, garage floors, and sidewalks to clear away algae, mud, tire marks, and general buildup without uneven striping.

• Concrete driveways and sidewalks—removes dirt, oil residue, and mildew.
• Paved patios and brick pavers—cleans joints and surfaces uniformly.
• Sealed wood or composite decks—use lower pressure settings to prevent damage.
• Garage and workshop floors—efficiently pull grime and lubricants from surfaces.

How do I maintain the attachment for long-lasting performance?

Routine rinsing and periodic inspection of jets and seals keep spray patterns consistent and prevent clogging. Store the cleaner dry and protected from freezing temperatures to extend the life of O-rings and swivel components.

• Flush with clean water after each use to clear detergent or debris.
• Inspect rotating arms and nozzles for blockages before use.
• Replace worn O-rings and seals as part of seasonal maintenance.
• Keep in a dry place and avoid freezing to protect internal parts.

Who is this for: The Greenworks 11" Surface Cleaner is ideal for homeowners and renters who regularly maintain patios, driveways, and other large, flat exterior surfaces and want a faster, cleaner finish than a standard wand provides. It also suits weekend DIYers and small property managers who already own a compatible Greenworks or standard-thread pressure washer and want to cut cleaning time while reducing overspray.
