Choosing a surface washer for pressure washer use comes down to a handful of practical questions: how much flat area you need to clean at once, what PSI and connector your machine uses, whether you want wheels to do the pushing, and how well the housing holds up to repeated use on concrete and wood. This guide compares six surface cleaner attachments sold on Amazon US. The selection method is research-based, drawing on listed specifications, brand reputation and common owner feedback patterns. None of these products were tested by us in a lab or in the field.

Buying Guide
Cleaning Width
Width is the single biggest factor in how long a job takes. A 20-inch cleaner covers roughly twice the area of a 12-inch unit per pass. For driveways and large patios, wider models save significant time. For steps, fence lines and narrow walks, a 12-inch housing gives you better control.
Good picks for this: WOJET 20″ Commercial Surface Cleaner, Westinghouse PWSC12 12″ Surface Cleaner
Pressure Rating and Machine Match
Check your pressure washer’s rated PSI and GPM before buying. Surface cleaners are designed to work within a machine’s output range. A high-PSI attachment on a low-output machine may not perform well, and a rating well above your machine’s output adds little benefit.
Good picks for this: Westinghouse Universal 16.5″ Surface Cleaner, Hourleey 14″ Surface Cleaner
Connector Type
Most surface cleaners use either a 1/4-inch or 3/8-inch quick-connect fitting. Confirm your machine’s outlet and wand connection before purchase. Adapters are available, but a mismatch can cause leaks or pressure loss.
Good picks for this: MEKOH 20″ Heavy-Duty Dual-Handle Surface Cleaner, Westinghouse PWSC12 12″ Surface Cleaner
Wheels and Ground Clearance
Wheels keep the cleaning head at a consistent distance from the surface, which helps avoid striping and uneven results. Four-wheel designs tend to track better on slightly uneven concrete. Look for wheels that roll freely and a housing that clears common curbs and expansion joints.
Good picks for this: Hourleey 14″ Surface Cleaner, JANZ 14″ Surface Cleaner
Housing Material and Durability
Stainless steel housings generally resist corrosion better than painted or plastic alternatives, especially when they stay wet between uses. Check weld quality and wheel mounts, since these are common failure points with repeated heavy use.
Good picks for this: Hourleey 14″ Surface Cleaner, WOJET 20″ Commercial Surface Cleaner
Accessories and Extension Wands
Some kits include extension wands and extra nozzles, which can help reach railings, undersides of decks and tight corners. Confirm what is included and whether replacement parts are easy to find.
Good picks for this: JANZ 14″ Surface Cleaner, Hourleey 14″ Surface Cleaner
Storage and Portability
A 20-inch housing can be difficult to store in a small garage. Measure your storage space and consider how you will move the unit between the garage and work area.

FAQ
What size surface washer should I buy?
For large driveways and open concrete, a 20-inch model covers ground fastest. For patios and decks, a 14-inch unit is a practical middle ground. For steps and narrow walkways, a 12-inch cleaner is easier to control.
Will a surface washer work with any pressure washer?
Not always. Check the attachment’s rated PSI, the machine’s output, and the connector type. Mismatched connectors may need an adapter, and attachments rated well below your machine’s output may not clean effectively.
Can I use a surface cleaner on wood decks?
Many owners use them on decks, but wood needs lower pressure and careful passes to avoid gouging. Use a wider nozzle or lower pressure setting, and keep the housing moving. Consult the manufacturer’s guidance for your deck material.
Why do surface cleaners leave streaks?
Streaking usually comes from uneven height, a clogged or worn nozzle, or inconsistent speed. Wheels help maintain height, and cleaning the nozzle before use reduces streaking.
Do I need wheels on a surface cleaner?
Wheels are not strictly required, but they keep the cleaning head at a steady distance from the surface and reduce operator fatigue on large jobs. Most owners find them worth having for driveways and patios.
Is a stainless steel housing necessary?
It is not essential, but stainless steel generally resists rust and corrosion better than painted or plastic housings, especially if the unit is stored damp.
Should I consult a professional before buying?
If you are unsure about pressure compatibility, connector sizing or safe use on a specific surface, consult a qualified equipment dealer or the manufacturer before purchase.
Conclusion
For most homeowners with large flat areas, a 20-inch surface washer such as the MEKOH or WOJET models offers the fastest coverage, provided the machine’s output and connector match. Mid-size patios and decks suit the 14-inch Hourleey or JANZ units, and the Westinghouse Universal works well for owners with either gas or electric machines. For narrow walkways and steps, the 12-inch Westinghouse PWSC12 gives better control. Match the cleaning width to your typical surface and confirm the connector and PSI before you buy.
