7 Top Patio Cleaner Picks
These patio cleaning solutions are ranked by cleaning power, surface safety, value, and ease of use, counting down to the top pick.
7. Westinghouse PWSC12 Pressure Washer Surface Cleaner
Best for: Electric pressure washer driveway cleaning
The Westinghouse PWSC12 is a 12-inch surface cleaner attachment for flat outdoor surfaces. It connects through a universal 1/4-inch quick-connect fitting and supports pressure washers rated up to 3,000 PSI and 2.3 GPM. Two rotating jets spray beneath the cleaning deck, covering a wider path than a standard wand. It suits driveways, patios, decks, sidewalks, garage floors, walls, and fences.
At about two pounds, this attachment should feel easier to move across open areas and lift onto vertical surfaces. Its skirt helps contain spray, which can reduce splashing onto nearby objects. The 12-inch width may cut cleaning time by up to four times compared with repeated wand passes, though results depend on the washer and surface condition. Around $26, it offers a practical way to clean large, flat areas with more even coverage. The compact shape also fits narrow walkways, steps, and corners better than larger surface cleaners.
Pros
- Two rotating jets provide more consistent coverage than a single spray wand.
- The 12-inch cleaning path can reduce repeated passes on driveways and garage floors.
- Two-pound weight makes stairs, walls, fences, and tight spaces easier to reach.
Cons
- It is intended for electric pressure washers, not gas-powered units.
- A 1/4-inch quick-connect fitting may still require an adapter for some machines.
6. MEKOH Pressure Washer Surface Cleaner
Best for: Homeowners cleaning large concrete areas
MEKOH’s 20-inch surface cleaner is a wheeled attachment for a separate pressure washer. It uses two spinning spray nozzles beneath a PP housing, with solid-brass parts and sealed bearings. Four casters hold the bar at a consistent height, which can help reduce stripes and protect the spray tips from scraping. The unit is rated up to 4,500 PSI and is listed for pressure washers producing at least 2 GPM and 2,000 PSI.
The wide 20-inch path should cover driveways, sidewalks, patios, and garage floors faster than a wand nozzle. Two angle-adjustable handles give you more control than a single grip, while the wheels support back-and-forth passes. Changeable nozzles allow a choice between more forceful and gentler cleaning patterns, based on the installed tips. The attachment accepts cold, hot, and soapy water, but your washer must support those conditions. Around $210, it costs more than small 10- to 15-inch cleaners. Check your connector type, flow rate, and pressure before ordering.
Pros
- 20-inch cleaning width suits driveways and patios.
- Four wheels keep nozzle height steady during passes.
- Two handles offer better control over the wide body.
Cons
- It cannot operate without a compatible pressure washer.
- Around $210 is a high upfront cost for occasional cleaning.
5. Greenworks Surface Cleaner Pressure Washer Attachment
Best for: Small driveway and patio cleaning
This Greenworks surface cleaner attachment gives a pressure washer a wider, more controlled cleaning path. Its 12-inch cleaning width suits driveways, sidewalks, patios, and decks, while helping reduce the narrow striping that can happen with a standard spray wand. It is an attachment, not a standalone cleaner, so you will need a compatible pressure washer and a water connection.
The fitting uses a 1/4-inch quick-connect design, which works with most pressure washers that accept this common connection. That makes it a practical option for owners who already have the right machine. At around $24, it costs less than many larger surface-cleaning attachments, but the smaller head may take more passes on broad concrete areas. Greenworks also covers it with a 3-year warranty, giving buyers a defined period of support if a covered problem appears. The listing does not state a rated pressure range, so confirm your washer’s connection and manufacturer guidance before ordering.
Pros
- The 12-inch head covers more ground than a handheld spray tip.
- A 1/4-inch quick connect fits most compatible pressure washers.
- The 3-year warranty adds coverage beyond the initial purchase.
Cons
- Its 12-inch width can make large driveways slower to clean than wider attachments.
- It will not work with every pressure washer, despite the common fitting.
4. TOR 14″ Pressure Washer Surface Cleaner
Best for: Large driveways and patios
The TOR 14-inch surface cleaner is a pressure washer attachment for flat concrete, patios, sidewalks, and decks. It connects to a pressure washer gun or wand through a 1/4-inch quick-connect plug, not directly to a garden hose. It supports machines rated from 2,000 to 4,000 PSI. If your washer has a 3/8-inch outlet, you will need a separate adapter. Its stainless steel housing should resist rust better than plastic models, while four caster wheels keep the nozzle height steady as you move it.
Inside, two rotating nozzles cover a wider path than a standard wand. The manufacturer claims cleaning can take up to five times less time, though actual speed depends on your washer’s pressure, water flow, and surface condition. A mesh inlet filter helps keep debris from reaching the nozzles. The package also includes two 15-inch extension wands, two replacement nozzles, four O-rings, a cleaning needle, and Teflon tape. At around $37, that is a useful set of included maintenance parts.
Pros
- Four wheels help the 14-inch cleaner glide across flat surfaces.
- Stainless steel construction offers better rust resistance than plastic housings.
- Included spare nozzles, O-rings, and cleaning tools reduce extra purchases.
Cons
- It will not work with a garden hose alone, and a 3/8-inch outlet requires an adapter.
- Caster wheels and the wide cleaning head may perform poorly on deeply uneven concrete.
3. Westinghouse Universal Surface Cleaner Attachment
Best for: Large patios, driveways, and decks
The Westinghouse Universal Surface Cleaner uses a 16.5-inch stainless steel housing to cover broad areas faster than a standard spray wand. It connects through a 1/4-inch quick-connect fitting and works with most gas and electric pressure washers. Its rated maximum pressure is 4,400 PSI, though your washer’s own pressure still sets the practical limit.
This attachment suits driveways, patios, decks, walls, and other large surfaces. The enclosed cleaner can help reduce overspray compared with using an open nozzle, while its wide cleaning path limits the number of passes needed. Around $90, it costs more than a basic wand but offers a more controlled option for recurring outdoor cleanup. Storage space may matter, since the 16.5-inch width is larger than a typical nozzle or lance. A 180-day limited warranty provides some coverage, but it is shorter than the warranty periods offered with some competing equipment.
Pros
- The 16.5-inch cleaning path covers broad flat areas with fewer passes.
- Stainless steel construction is suited to repeated outdoor use.
- The 1/4-inch quick-connect fitting works with most gas and electric pressure washers.
Cons
- Compatibility is not universal, so users should confirm their washer has a matching 1/4-inch connection.
- The wide head is less useful for stairs, corners, narrow walkways, and small detail work.
2. Hourleey 14-Inch Pressure Washer Surface Cleaner
Best for: Concrete driveways and wide patios
The Hourleey surface cleaner covers a 14-inch path, measured from the outside edge of one wheel to the other. Its stainless steel body and heavy-duty bearing are built for pressure-washer cleaning across driveways, patios, sidewalks, decks, and pathways. Four wheels rotate 360 degrees, helping the cleaner move across broad, flat areas with less repositioning.
The unit connects through a standard 1/4-inch quick plug and works within a 2,000 to 4,000 PSI range. Hourleey recommends using a pressure washer rated at 2,500 PSI or higher for stronger cleaning. The package includes two extension wands, a nozzle cleaner, thread seal tape, four O-rings, and two replacement nozzles. Around $36, it offers a fairly complete setup for homeowners who want faster coverage than a spray wand provides.
Pros
- 14-inch cleaning width: Covers more concrete with each pass than a narrow pressure-washer nozzle.
- Four rotating wheels: Improves movement and control across large, flat surfaces.
- Useful spare parts: Includes replacement nozzles, four O-rings, seal tape, and a nozzle-cleaning tool.
Cons
- Requires enough pressure: Performance may be limited with pressure washers below the suggested 2,500 PSI level.
- Best on flat surfaces: The wheeled design is less practical on steps, uneven ground, walls, or tight corners.
1. Simple Green Oxy Solve Outdoor Cleaner Concentrate
Best for: Large outdoor cleaning projects
Simple Green Oxy Solve Total Outdoor Cleaner is a peroxide-based concentrate for outdoor maintenance. It can be used with a pressure washer or applied by hand, depending on the job. The formula is intended for wood decks, vinyl siding, concrete driveways, brick, composite surfaces, patios, fences, and outdoor furniture. Its EPA Safer Choice certification may appeal to households that want a cleaner with a clearer ingredient-safety profile around children and pets. It is still a chemical cleaner, so label directions and protective measures matter.
The strongest practical feature is coverage. One bottle can clean up to 6,400 square feet, which suits spring cleanup, property staging, storefront maintenance, and larger contractor jobs. That area could include several patios or walkways, though actual coverage depends on dilution, surface porosity, and grime. Around $24, it costs less upfront than booking a pressure-washing service, but the buyer still needs equipment or time for manual scrubbing. It targets visible outdoor buildup across multiple materials instead of focusing on one surface.
Pros
- Covers up to 6,400 square feet per bottle for broad property cleanup.
- Works with pressure washers or manual application, giving users two ways to apply it.
- Suitable for wood, vinyl, concrete, brick, and composite surfaces.
Cons
- The concentrate requires dilution and application work, so it is not a spray-and-rinse shortcut.
- Heavy grime may still require scrubbing or pressure-washing equipment, adding time and effort.
Buying Guide
The most important factor is pressure and flow compatibility. A patio surface cleaner only spins correctly when its rated PSI and GPM match your washer, so a poor match can leave streaks or damage the attachment.
- Pressure and flow rating: Choose a model rated for your machine’s output, such as 2,000-4,000 PSI and 2-4 GPM. Never exceed the attachment’s maximum rating.
- Cleaning width: Pick a 12- to 15-inch deck for small patios and walkways. A 16- to 20-inch model covers larger areas faster but needs more water flow.
- Connector fit: Look for a standard 1/4-inch quick-connect plug. Verify the included adapter matches your pressure washer wand or hose.
- Build and handling: Stainless steel or powder-coated metal decks usually resist rust better than thin plastic. Two wheels and a skirt help keep the cleaner level and reduce splashback.
- Nozzles and upkeep: Select models with replaceable spray tips and accessible fittings. A $50-$120 attachment is common, while replacement nozzle sets often cost $10-$25.
If you cannot have everything, prioritize pressure and flow compatibility, because the wrong rating can prevent proper cleaning and shorten the unit’s life.
Frequently Asked Questions
How do I choose a patio cleaner for my pressure washer?
Choose a pressure-washer patio cleaner that matches your surface, machine, and the type of dirt you need to remove. For concrete, choose one labeled for masonry and pressure-washer use. For sealed stone, pick a gentler formula. Check dilution directions, since concentrates may mix at ratios such as 1:10, while ready-to-use products need no mixing.
What is the best patio detergent for a pressure washer?
The best choice is a detergent labeled for pressure washers and your patio’s surface, not a general household cleaner. Concrete often tolerates stronger formulas than natural stone, painted surfaces, or sealed pavers. A 1-liter concentrate can make several diluted batches, but coverage depends on the mix ratio and patio size.
Can I use bleach in a pressure washer patio cleaner?
You can use a bleach-based patio cleaner only when its label permits pressure-washer use and your surface can tolerate it. Bleach may damage plants, fabrics, metal fittings, colored pavers, and some sealers. Rinse nearby vegetation before and after cleaning, and never mix bleach with acids or ammonia.
Are patio cleaners safe for pressure washers?
Patio cleaners are generally safe for pressure washers when the label allows machine application and you follow its dilution and nozzle directions. Do not pour every outdoor cleaner into the detergent tank, because thick formulas or solvents can harm seals and pumps. Use low-pressure detergent mode when available, then rinse with clean water.
Conclusion
Simple Green Oxy Solve Outdoor Cleaner Concentrate is the top pick for homeowners who want a versatile patio wash for routine outdoor cleaning and pressure-washer projects. If your main priority is the lowest possible cost per use, choose a larger concentrated formula, provided it matches your machine and the surface you need to clean. Before buying, double-check the bottle size, pressure-washer compatibility, number of uses or dilution ratio, and current price. Also confirm that the cleaner suits concrete, brick, stone, or pavers, since surface directions can differ. Follow the label’s mixing instructions, use appropriate eye protection, and rinse nearby plants thoroughly. A good match saves product, protects surfaces, and makes patio maintenance easier.
