Key takeaways
- Compatibility: Check the pressure washer’s maximum PSI, hose fitting, and quick-connect size before ordering; a 1/4-inch connector and a 3/8-inch connector are not interchangeable without the correct adapter.
- Cleaning width: A 14- or 15-inch cleaner is easier to steer around steps and furniture, while a 16.5- or 20-inch model can reduce passes across a large driveway.
- Pressure rating: Choose an attachment rated at or above your pressure washer’s maximum output. Do not assume a higher rating makes every machine clean more effectively.
- Wheels and handling: Four wheels can make long sessions less tiring, but smooth rolling depends on a reasonably flat surface and a housing that remains balanced during use.
- Surface and technique: These tools are best for durable, relatively flat materials such as concrete and sealed decking. Begin with a test area, keep the cleaner moving, and avoid delicate finishes.
What's inside
Cleaning a driveway, patio, or deck with a bare pressure-washer wand can be slow, tiring, and surprisingly difficult to keep even. The narrow spray often leaves visible stripes, while overspray can reach siding, furniture, vehicles, and nearby garden beds.
From a home-appliance testing lab perspective, a surface cleaner is the better tool for broad, flat areas: its enclosed housing helps contain spray, while rotating jets cover more ground in a consistent pattern. This guide compares pressure-washer attachments by working width, connector compatibility, maneuverability, construction, and suitability for common household surfaces.

The Best Surface Cleaner For Pressure Washer (2026)s Reviewed
Westinghouse Universal 16.5-Inch Surface Cleaner
The Westinghouse Universal 16.5-inch attachment is a strong all-purpose choice for homeowners who want broad coverage without moving to an especially large, cumbersome tool. Its stainless-steel housing and 4,400-PSI rating suggest useful durability for demanding concrete and patio jobs, while the 1/4-inch connector suits many gas and electric pressure washers.
Hourleey 14-Inch Surface Cleaner
Hourleey’s 14-inch model is a practical fit for routine residential cleaning, particularly where maneuverability matters more than maximum coverage. Four wheels, two extension wands, and a stainless-steel body make it well equipped for sidewalks, decks, patios, and smaller driveway sections; verify that the supplied fittings match your washer before use.
MEKOH 20-Inch Heavy-Duty Surface Cleaner
The MEKOH 20-inch cleaner is designed for large, open areas where reducing the number of passes is the priority. Its dual-handle layout can provide better control over a wide housing, but that generous footprint is best suited to flat driveways and sidewalks rather than tight spaces or detailed work near edges.
Westinghouse Universal 15-Inch Surface Cleaner
This 15-inch Westinghouse attachment occupies a useful middle ground: it should cover more area than a compact cleaner while remaining easier to guide than a 20-inch unit. The 3,400-PSI rating makes it especially important to compare the attachment’s limits with the pressure washer’s output before connecting it.
LidoDola 14-Inch Surface Cleaner
LidoDola’s 14-inch accessory combines a four-wheel stainless-steel housing with two extension wands and replacement nozzles, giving buyers useful maintenance flexibility. It is a sensible option for standard residential surfaces, though nozzle care remains essential: grit or mineral buildup can affect spray balance and produce uneven cleaning.
Frequently Asked Questions
What is a surface cleaner attachment used for?
A surface cleaner uses one or more rotating spray nozzles beneath a protective housing to clean broad, flat surfaces more evenly than a handheld wand. It is commonly used on concrete driveways, patios, sidewalks, and some durable decks.
Can a surface cleaner be used with an electric pressure washer?
Yes, provided the attachment’s connector and pressure rating are compatible with the electric washer. Lower-powered machines may clean more slowly, and heavily stained concrete may require additional detergent, dwell time, or a second pass.
Will a surface cleaner remove every stain?
No. These attachments are effective against general dirt, grime, algae, and surface soil, but oil, rust, paint, and deeply embedded organic staining may need a suitable pretreatment. Always follow the cleaner and pressure-washer manufacturer’s instructions.
Why does a pressure-washer surface cleaner leave stripes?
Striping can result from moving too quickly, using a partially blocked nozzle, operating at an unsuitable pressure, or holding the housing unevenly. Clean both nozzles, inspect the swivel, overlap each pass slightly, and test the technique on a small area first.
Final Thoughts
For most homeowners, the Westinghouse Universal 16.5-inch model is a compelling balance of coverage and build, while the Hourleey 14-inch and LidoDola 14-inch are easier choices for everyday residential jobs. Choose the MEKOH 20-inch when driveway productivity matters most, and confirm connector size, PSI limits, and surface suitability before starting.
