The Westinghouse 16.5-inch surface cleaner attachment is a game-changer for anyone looking to speed up pressure washing tasks. Designed for flat surfaces like driveways, patios, and sidewalks, this accessory connects to most gas and electric pressure washers via a universal 1/4-inch quick-connect fitting. Whether you're a homeowner tackling spring cleaning or a professional contractor, this tool promises to deliver professional-level results with minimal effort.
One of the standout features is its wide 16.5-inch cleaning path, which cuts cleaning time significantly compared to using a standard spray wand. The stainless steel construction ensures durability and resistance to corrosion, even with frequent use. Rated up to 4400 PSI, it easily removes stubborn dirt, grime, and mildew from concrete, brick, and wood surfaces. Users appreciate how it leaves a streak-free finish, eliminating the common tiger-striping effect of manual wand washing.
The design is thoughtful, with a lightweight body that reduces arm fatigue during long sessions. It works well on both horizontal and vertical surfaces, making it versatile for cleaning walls, fences, and even car floors. The quick-connect system allows for seamless attachment changes, and the included components are straightforward to assemble. However, some users note that the included hose length is short, so you may need an extension hose for large areas.
While this surface cleaner excels on flat, even surfaces, it is not ideal for uneven or curved areas, as the rotating arms may skip over bumps. Additionally, it requires a pressure washer with a 1/4-inch connector; those with 3/8-inch fittings will need an adapter. Despite these minor limitations, the overall performance and build quality are impressive for the price.
In conclusion, the Westinghouse 16.5-inch surface cleaner is a reliable, high-performing accessory that delivers excellent value. It's a must-have for anyone who regularly cleans large flat areas and wants to save time and effort. With a 180-day warranty and a trusted brand name, this attachment is a solid investment for both DIY enthusiasts and professionals.

Buying Guide: What to Look for in a Pressure Washer Surface Cleaner
Cleaning Width and Coverage
The wider the cleaning path, the faster you finish. A 16.5-inch model like the Westinghouse is great for driveways and patios, while a 20-inch unit like the MEKOH covers even more ground on large concrete areas. Think about the size of the surfaces you clean most often before you choose.
Narrower units are easier to maneuver around obstacles, but they demand more passes. If you regularly clean a long driveway or a big patio, the extra width pays off quickly. For smaller spaces, a compact design keeps storage simple.
Pressure Rating and Compatibility
Check your pressure washer’s PSI and GPM before buying. The Westinghouse handles up to 4400 PSI with a 1/4-inch quick-connect fitting, so it works with most gas and electric machines. The MEKOH is rated for 4500 PSI and requires at least 2000 PSI and 2 GPM for best results.
Matching the attachment to your machine prevents weak cleaning or unnecessary wear. Always confirm your washer’s flow rate, because a surface cleaner needs enough water volume to spin its nozzles properly. Just as you’d pair the right air filter with your furnace, pairing the right attachment with your pressure washer makes all the difference. Check our guide to the best 16x25x4 furnace filters for allergies for more on matching components.
Build Quality and Materials
Stainless steel, like the Westinghouse, resists corrosion and handles heavy use. The MEKOH uses lightweight polypropylene with solid brass fittings and a sealed bearing to prevent leaks. Both approaches work, but your choice depends on whether you prioritize weight or rugged metal construction.
Look for features like replaceable nozzles and sealed bearings. These details extend the life of the attachment and keep water where it belongs, so you stay dry and the machine keeps performing.
Maneuverability and Ease of Use
The MEKOH stands out with four universal wheels and two angle-adjustable handles, making it feel like a floor buffer rather than a wand. The Westinghouse is simpler, with a straightforward design that works well for quick jobs and tight spaces.
If you have a large area to cover, wheels reduce fatigue and protect your floors from nozzle scratches. For occasional use, a lighter attachment without wheels is easier to store and carry.

Final Thoughts
For most homeowners, the Westinghouse Universal 16.5” Pressure Washer offers the best balance of power, durability, and value for everyday driveways and patios. If you tackle large commercial-style surfaces and want maximum coverage with less effort, the MEKOH 20” Heavy-Duty Pressure Washer Surface is the better partner. Whichever you choose, you’ll leave streaks behind and get your weekends back.
Frequently Asked Questions
How does a pressure washer surface cleaner work?
A surface cleaner attaches to your pressure washer wand and spins two or more high-pressure jets under a protective shroud. The spinning action breaks up dirt evenly, while the shroud contains spray to prevent splashing and streaks. This lets you clean flat surfaces quickly without bending over.
Will a surface cleaner work with my pressure washer?
Most surface cleaners work with both gas and electric pressure washers, but you need to check the PSI and GPM ratings. The Westinghouse model handles up to 4400 PSI with a 1/4-inch quick-connect, while the MEKOH requires at least 2000 PSI and 2 GPM. Always confirm compatibility before you buy.
What is the best surface cleaner for driveways in 2026?
For driveways, the MEKOH 20” Heavy-Duty Pressure Washer Surface is a top choice because its wide deck and wheels cover large areas fast. The Westinghouse 16.5” model is also excellent for smaller driveways and patios. Both deliver streak-free results on concrete, brick, and pavers.
How do I prevent streaks when using a surface cleaner?
Keep the attachment flat and move it at a steady pace, overlapping each pass slightly. Check the nozzles for clogs and make sure your pressure washer provides enough water flow.
