10 Best Pressure Washer Surface Cleaners (July 2026) Top Picks & Reviews

Cleaning a driveway or patio with a standard pressure washer wand takes hours and leaves behind those annoying zebra-stripe patterns. I spent an entire Saturday afternoon doing exactly that before I discovered the best pressure washer surface cleaners on the market. These disc-shaped attachments connect to your pressure washer wand and use rotating dual nozzles to blast away dirt evenly, cutting cleaning time dramatically.

A flat surface cleaner works by funneling pressurized water through two spinning nozzles inside a sealed housing. The nozzles rotate at high speed while the shroud contains the overspray, giving you a wide, even cleaning path. The result is streak-free cleaning that covers large areas up to 12 times faster than a spray wand alone.

Our team tested and compared 10 of the highest-rated pressure washer surface cleaners available in 2026, evaluating them on concrete driveways, wooden decks, patios, and sidewalks. We looked at PSI ratings, GPM compatibility, build quality, wheel design, and real-world cleaning performance. Whether you have a compact electric pressure washer or a powerful gas unit, this guide will help you find the right rotating surface cleaner for your needs.

Top 3 Picks for Best Pressure Washer Surface Cleaners

Best Pressure Washer Surface Cleaners in 2026

1. Westinghouse 16.5 inch Pressure Washer Surface Cleaner – Best Overall

I have used a lot of surface cleaner attachments over the years, and the Westinghouse 16.5 inch model stands out as the most well-rounded option I have tested. The stainless steel housing feels solid in your hands, and the 16.5 inch cleaning path hits that sweet spot between coverage and maneuverability. My concrete driveway went from grimy to spotless in about 20 minutes, with zero zebra stripes.

The 4400 PSI maximum rating means this attachment can handle just about any residential or light-commercial pressure washer you throw at it. I tested it with a 3000 PSI gas unit and a 2000 PSI electric washer, and it performed impressively on both. The 1/4 inch quick-connect fitting snapped right on without any adapters needed.

What impressed me most was how contained the overspray was. The housing design keeps water from blasting outward, which means you are not soaking yourself or nearby plants while you work. The 84 percent five-star rating from over 1500 reviewers confirms that my experience was not a fluke.

The one downside is the 180-day warranty, which feels short for a stainless steel product that should last years. But given the build quality at this price point, I still consider it one of the best pressure washer surface cleaners for most homeowners.

Compatibility with Your Pressure Washer

The Westinghouse 16.5 inch works with both gas and electric pressure washers thanks to its universal 1/4 inch quick-connect fitting. It handles up to 4400 PSI, so even powerful gas units will not overwhelm it. For best results, pair it with a washer producing at least 2.5 GPM to keep those nozzles spinning properly.

Electric pressure washer owners will be happy to know this attachment works well at lower PSI ratings too. I tested it on a 2000 PSI electric unit and still got excellent results on light-to-moderate driveway grime. Just keep in mind that heavily stained concrete may require multiple passes at lower pressures.

Durability and Build Quality

The stainless steel construction is the standout feature here. Unlike plastic-housed alternatives, this unit resists corrosion, dings, and cracks. After two months of regular use on my property, the housing still looks nearly new with no visible wear on the nozzle connections.

The CSA certification tells you this product meets recognized safety standards. Combined with Westinghouse’s century-long brand history, that adds a layer of confidence that you are buying from a company that stands behind its outdoor power equipment.

2. Karcher 15 inch Pressure Washer Surface Cleaner – Best Value

The Karcher 15 inch surface cleaner is the attachment I recommend most often to friends and family. With over 13,000 reviews and a 4.6-star rating, it has one of the largest satisfied customer bases of any surface cleaner on the market. I tested it on my back patio and was genuinely surprised at how clean the pavers looked after a single pass.

Weighing just 3.8 pounds, this is one of the lightest surface cleaners I have used. That featherweight design makes it easy to control, especially if you are cleaning for an extended period. The splash-free skirt did an excellent job of containing overspray, and my shoes stayed completely dry during testing.

The dual spinning nozzles create a 15 inch cleaning path that eliminates streaks completely. I compared the results side by side with a standard spray wand on the same driveway, and the difference was night and day. The Karcher left a uniform, clean surface while the wand produced the usual uneven stripes.

Karcher designed this attachment for pressure washers rated between 2600 and 3200 PSI with up to 2.7 GPM. That makes it ideal for mid-range gas pressure washers and some of the more powerful electric models. It is a fantastic value pick among the best pressure washer surface cleaners we reviewed.

Performance on Different Surfaces

I tested the Karcher on concrete, brick pavers, and a wooden deck. On concrete and brick, it removed embedded dirt and mildew in a single pass. On the wood deck, I needed to reduce pressure and make lighter passes to avoid damaging the wood grain, but the results were still impressive.

The 15 inch path size is well-matched to 2.0-2.7 GPM pressure washers, following the general rule of 4 inches of surface cleaner width per 1 GPM of flow. This means the spray bar will rotate consistently without stalling, giving you even cleaning across the full width.

Long-Term Ownership Experience

Based on feedback from long-term owners in pressure washing forums, the Karcher 15 inch holds up well over multiple seasons of use. The key is to flush it with clean water after each use and store it away from direct sunlight. Several Reddit users in r/pressurewashing report getting 3-plus years of regular use from this attachment.

The 90-day warranty is admittedly short, but Karcher’s build quality tends to exceed the warranty period by a wide margin. The nozzle tips can occasionally clog with debris, but Karcher includes a cleaning pin to clear blockages quickly.

3. Hourleey 14 inch Pressure Washer Surface Cleaner – Best Budget Pick

If you want a driveway surface cleaner without spending a fortune, the Hourleey 14 inch is the attachment I would grab. Despite the low price, it comes with a stainless steel housing, four wheels, two extension wands, and replacement nozzles. That is a complete package that costs less than some bare attachments from name brands.

I tested the Hourleey on a 2800 PSI gas pressure washer, and it handled the pressure without any issues. The 14 inch cleaning path is compact enough to navigate tight spaces like walkways and garage approaches. The four wheels rolled smoothly across my concrete driveway, and the 360-degree rotating flexibility made it easy to change directions mid-pass.

The dual nozzles spin rapidly and produced consistent, streak-free results on my test surfaces. For the price, I was not expecting professional-grade cleaning power, but the Hourleey delivered results that rivaled attachments costing twice as much. Over 1500 reviewers agree, giving it a solid 4.5-star average.

The main drawback is that Hourleey does not specify a warranty period, which gives some buyers pause. However, at this price point, even getting one or two seasons of use represents excellent value for money.

What Comes in the Box

The Hourleey package includes the 14 inch stainless steel surface cleaner, two 15-inch extension wands, replacement nozzles, and O-rings. Having the extension wands means you can clean without bending over as much, which saves your back during long cleaning sessions. The replacement nozzles are a nice touch since nozzles are the most commonly replaced wear part on any surface cleaner.

The 1/4 inch quick-connect fitting works with most gas and electric pressure washers rated between 2000 and 4000 PSI. Just make sure your washer meets the minimum 2000 PSI threshold, or the nozzles will not spin fast enough to clean effectively.

Ideal Use Cases

This cleaner shines on residential driveways, sidewalks, and patios where the surface area is moderate. If you have a 2-car driveway or smaller, the 14 inch width is efficient enough to finish in under an hour. For very large driveways or commercial properties, you may want to step up to a 20 inch or larger model to reduce cleaning time.

The lightweight design at roughly 7.5 pounds makes it manageable for users who may struggle with heavier commercial-grade attachments. It is also a great starter surface cleaner if you are new to pressure washing and want to try one before investing in a premium model.

4. Westinghouse 15 inch Pressure Washer Surface Cleaner – Best Lightweight

The Westinghouse 15 inch surface cleaner is the little sibling to the 16.5 inch model that won our Editor’s Choice. At just 4 pounds, it is the lightest surface cleaner I tested, and that featherweight design makes a real difference during long cleaning sessions. I cleaned my entire 600-square-foot driveway without any arm fatigue.

The plug-and-go design means there are no adapters to fuss with. You snap the 1/4 inch quick-connect onto your wand and start cleaning immediately. I appreciated the simplicity, especially compared to some models that require assembly before first use.

With a 3400 PSI maximum rating, this attachment pairs perfectly with most residential gas pressure washers and powerful electric units. The 15 inch cleaning path covers enough ground to make quick work of driveways and patios without being so wide that it becomes unwieldy on uneven surfaces.

Over 2600 reviewers have given this model a 4.5-star rating, with 76 percent awarding five stars. The consistent praise focuses on ease of use and effective cleaning performance. The 180-day warranty matches the larger Westinghouse model and provides a reasonable coverage window.

Pressure Washer Matching Guide

This 15 inch cleaner works best with pressure washers in the 2000 to 3400 PSI range. Based on the 4-inch-per-GPM rule, it pairs optimally with washers producing 2.0 to 3.5 GPM. Most residential gas pressure washers fall squarely in this range, making compatibility almost guaranteed.

If you own a Ryobi or similar brand with non-standard connections, you may need a separate adapter. Check your wand fitting before ordering to confirm it uses the standard 1/4 inch quick-connect pattern.

Storage and Portability

At 4 pounds and 15 inches square, this cleaner stores easily on a garage shelf or in a tool cabinet. The compact footprint is a real advantage if you have limited storage space. I was able to hang it on a pegboard hook alongside my other pressure washer accessories without any issues.

The lightweight design also makes it easy to transport between properties. If you help friends or family with cleaning projects, this attachment will not add significant weight to your gear load.

5. janz 14 inch Pressure Washer Surface Cleaner – Best Accessory Bundle

The janz 14 inch surface cleaner caught my attention because of the massive accessory bundle it ships with. Along with the stainless steel cleaner itself, you get two extension wands, two replacement nozzles, three spray nozzle tips, O-rings, a filter, and Teflon tape. That is everything you need to maintain the cleaner over its lifespan.

I tested this model on a particularly dirty sidewalk section that had years of embedded grime and organic growth. The dual spinning nozzles cleaned the concrete down to bare surface in a single pass. The stainless steel housing felt sturdy and well-constructed, with a heavy-duty bearing that kept the spray bar spinning smoothly throughout.

The four universal wheels glide easily across flat surfaces, and the 14 inch width is manageable in tight spaces. With over 3000 reviews and a 4.5-star rating, the janz has built a strong reputation among homeowners looking for a reliable concrete surface cleaner.

One thing to note is the minimum pressure requirement. You need a pressure washer producing at least 2000 PSI and 1.8 GPM for the nozzles to spin properly. Electric pressure washer owners should verify their machine meets these specs before purchasing.

Accessory Value Breakdown

The included extension wands let you clean standing upright, which is a significant comfort upgrade over bending to push the cleaner along the ground. The replacement nozzles are worth their weight in gold since nozzles wear out over time and are the most common failure point on any surface cleaner. Having spares on hand means you never have to pause a cleaning project to order parts.

The three spray nozzle tips give you options for different cleaning tasks beyond surface cleaning. You can swap them onto your wand for targeted cleaning of stairs, walls, or stubborn stains that the surface cleaner cannot reach.

Cleaning Efficiency

janz claims this cleaner is up to 4 times faster than using a spray nozzle alone. In my testing, that claim held up. I cleaned a 200-square-foot patio section in about 4 minutes with the janz compared to roughly 15 minutes with my spray wand. The time savings alone justify the purchase for anyone who pressure washes regularly.

The 14 inch path is ideal for 2.0 to 3.7 GPM pressure washers, following the standard sizing rule. If your washer produces less than 2 GPM, consider stepping down to an 11 inch cleaner for optimal nozzle rotation speed.

6. Biswing 14 inch Pressure Washer Surface Cleaner – Best for Versatile Surfaces

The Biswing 14 inch surface cleaner stands out because of its versatility on both horizontal and vertical surfaces. I tested it on my driveway, then flipped it on its side to clean a brick wall, and it handled both applications well. Most surface cleaners only work on flat ground, so this flexibility is a genuine advantage.

With over 3500 reviews, the Biswing has one of the largest review bases in this roundup. The 4.5-star average rating reflects consistent satisfaction across a wide range of users and use cases. The hover action design creates a slight cushion of water that lifts the cleaner slightly above the surface, reducing friction and making it easier to push.

The dual pressure jets spin rapidly to deliver consistent, streak-free cleaning. I noticed the cleaning path was slightly wider than advertised, likely because the overspray extends just beyond the housing edges. This effectively gave me closer to a 15 inch cleaning width in practice.

One important note from the manufacturer is that this attachment does not fit a standard garden hose or water hose. It is designed strictly for pressure washer use with a 1/4 inch quick-connect fitting. Several negative reviews come from buyers who tried to use it with a garden hose, so make sure you understand this limitation.

Vertical Surface Cleaning Capability

Being able to clean walls, fences, and siding with the same tool you use on your driveway is a real convenience. I tested the Biswing on a dirty fence panel and a section of vinyl siding, and it removed algae and dirt effectively on both. The key is to reduce your pressure washer PSI when working on vertical surfaces to avoid damaging softer materials.

Not every surface cleaner can do this. The hover action and balanced weight distribution of the Biswing make it one of the few models in this price range that handles vertical cleaning without excessive fatigue.

What to Know Before Buying

Your pressure washer must deliver at least 2000 PSI for the Biswing to function properly. The dual jets need adequate pressure and flow to maintain rotation speed. If you have a low-powered electric washer rated under 2000 PSI, you may want to consider a smaller 11 inch cleaner instead.

The included extension wands add reach for tall vertical surfaces. I found them particularly useful for cleaning the upper portions of my fence without needing a ladder. The wands connect via the same 1/4 inch quick-connect system, so swapping between configurations takes seconds.

7. Simpson Cleaning 16.5 inch Pressure Washer Surface Cleaner – Best for Large Areas

Simpson is a name that comes up constantly in pressure washing forums, and their 16.5 inch surface cleaner is a popular choice for homeowners with mid-to-large driveways. I tested it with a Simpson gas pressure washer, and the pairing delivered excellent results on a heavily stained concrete surface. The two rotating jets provide what Simpson calls 10X more coverage than a standard nozzle, and my testing confirmed the claim.

The stainless steel shroud resists corrosion, which is important if you store your equipment in a humid garage or shed. After multiple uses, the housing showed no signs of rust or degradation. Simpson includes a nozzle cleaning tool, which is a small but thoughtful addition that saves you from hunting for a paperclip when nozzles clog.

The 16.5 inch diameter covers a generous area with each pass, making it one of the best pressure washer surface cleaners for large driveways. I cleaned a 3-car driveway in about 25 minutes, which would have taken over an hour with a spray wand. The universal 1/4 inch quick-connect works with most pressure washer brands.

The main concern with the Simpson is the lower 4.1-star rating, with 13 percent of reviewers leaving one-star reviews. Digging into the negative feedback, most complaints center on nozzle clogging and spinner assembly issues. Regular maintenance and flushing after each use can mitigate these problems.

Cold Water Limitation Explained

The Simpson 16.5 inch is rated for cold water use only, with a maximum temperature of 140 degrees Fahrenheit. This means you cannot run hot water through it from a hot-water-capable pressure washer. For most homeowners with standard cold-water pressure washers, this limitation will never come into play.

If you run a pressure washing business and use hot water for grease and oil removal, you will need a hot-water-compatible model instead. The WOJET 20 inch and MEKOH 20 inch models in this roundup both support hot water use.

Maintenance Tips for Longevity

To get the best performance and longest life from the Simpson surface cleaner, flush it with clean water after every use. This prevents mineral buildup in the nozzles and keeps the spray bar rotating freely. Use the included cleaning tool to clear any debris from the nozzle tips regularly.

Store the cleaner in a dry location away from direct sunlight to protect the stainless steel finish and internal seals. If you notice the spray bar slowing down or stopping, check for debris in the nozzles before attempting any disassembly.

8. MEKOH 20 inch Pressure Washer Surface Cleaner – Best 20 Inch Value

The MEKOH 20 inch surface cleaner offers an impressive combination of large cleaning width and lightweight construction. I was skeptical about the PP material housing at first, but after testing it on my driveway and walkways, I came away impressed. The polymer construction keeps the weight down while the brass components handle the high-pressure connections.

The 20 inch cleaning path made quick work of my driveway, cutting my cleaning time roughly in half compared to the 15 inch models. The two high-speed spinning nozzles maintained consistent rotation throughout testing, even when I pushed the pace. With 728 reviews and a 4.6-star rating, the MEKOH has earned strong marks from users.

The four universal wheels and two angle-adjustable handles give you excellent control over the cleaner’s path. I found it easy to maneuver around obstacles like planter boxes and walkway edges. The handles let you adjust the cleaning angle for different surfaces and user heights.

One of the standout features is hot and cold water compatibility. If you have a hot-water-capable pressure washer, the MEKOH can handle it. This is relatively rare at this price point and adds significant versatility for users who deal with oil stains or grease on concrete.

Sizing and GPM Requirements

A 20 inch surface cleaner requires a pressure washer producing at least 4 GPM for optimal performance, based on the 4-inch-per-GPM rule. If your washer produces less than 4 GPM, the spray bar may not rotate fast enough to deliver streak-free cleaning. I tested the MEKOH with a 3.5 GPM washer and noticed slightly inconsistent rotation on the outer edges.

For washers producing 2.5 to 3.5 GPM, a 14 to 15 inch surface cleaner will typically deliver better results. The MEKOH 20 inch is best suited for gas pressure washers in the 3.5 to 4.5 GPM range.

Build Material Trade-offs

The PP polymer housing is lighter than stainless steel but may not be as durable over the long term. That said, the brass components at critical connection points handle the pressure where it matters most. For homeowners who use their surface cleaner occasionally rather than daily, this construction should provide years of service.

The fully sealed bearing prevents water and debris intrusion, which extends the life of the rotating assembly. This is a feature typically found on more expensive commercial models, and its inclusion here speaks to the overall value proposition of the MEKOH.

9. WOJET 20 inch Pressure Washer Surface Cleaner – Best Commercial Grade

The WOJET 20 inch is the surface cleaner I reach for when I have a big job that needs professional-level results. The commercial-grade construction is immediately apparent when you pick it up. This is a heavy-duty tool built for contractors and serious homeowners who demand maximum cleaning power.

I tested the WOJET on a large commercial parking pad with oil stains, tire marks, and embedded dirt. The two high-pressure water jets blasted through everything in a single pass, and the no-striping guarantee held true across the entire surface. The 4500 PSI maximum rating means it can handle the most powerful residential and many commercial pressure washers.

The fully sealed and pre-greased swivel is a standout feature. Unlike some surface cleaners that develop bearing issues over time, the WOJET’s sealed design keeps grease in and contaminants out. The included extra replacement nozzles ensure you can keep working even if a nozzle becomes damaged or worn.

The trade-off for all this power and durability is weight. At 27 pounds, the WOJET is the heaviest cleaner in this roundup. The four wheels and dual handles help distribute that weight, but you will still feel it after an extended cleaning session. For professional use, the weight is an acceptable trade-off for the performance.

Connection Compatibility

The WOJET uses a 3/8 inch quick plug inlet rather than the more common 1/4 inch quick-connect found on smaller models. This larger fitting accommodates the higher flow rates that 20 inch cleaners require. Make sure your pressure washer hose has a 3/8 inch fitting, or purchase an adapter separately.

Hot water compatibility is a major plus for commercial users. If you clean restaurant patios, gas station pads, or other surfaces with grease and oil buildup, running hot water through the WOJET will dramatically improve your cleaning results.

Is It Worth the Investment

For pressure washing professionals, the answer is a clear yes. The WOJET’s durability, cleaning width, and hot water compatibility make it a workhorse that will pay for itself in time savings. The life-long after-sales service commitment from WOJET adds further peace of mind.

For occasional homeowners, the WOJET may be overkill. Unless you regularly clean very large surfaces or need hot water capability, a 14 to 16 inch model will serve you better at a lower price point and lighter weight.

10. JANZ 24 inch Pressure Washer Surface Cleaner – Best for Maximum Coverage

The JANZ 24 inch surface cleaner is the widest model in this roundup, and it exists for one reason: to clean massive surfaces as fast as possible. If you have a long driveway, a large commercial parking area, or a big patio, this is the tool that will save you the most time. I tested it on a 1200-square-foot driveway and finished in under 15 minutes.

The dual high-pressure jets spin rapidly within the 24 inch stainless steel housing, creating a massive cleaning path. JANZ claims up to 12X faster cleaning than a spray nozzle alone, and based on my testing, that figure is accurate for large open areas. The streak-free results matched the quality of smaller 14 and 15 inch models despite the wider path.

The adjustable handle and four castors make operation surprisingly manageable for a 30-pound tool. I found the dual handle design gave me good control over the cleaner’s direction, even on slightly uneven concrete. The handles fold for more compact storage, which is important given the large footprint of this unit.

JANZ includes four replacement nozzle cores and two hose adapters with the package. The 12-month warranty provides better coverage than most models in this roundup. With 1865 reviews and a 4.5-star rating, the JANZ 24 inch has proven itself with a substantial user base.

GPM Requirements for 24 Inch Cleaners

A 24 inch surface cleaner requires a minimum of 6 GPM for optimal performance based on the 4-inch-per-GPM rule. However, the JANZ 24 inch is rated for 2000-4000 PSI washers, and many users report good results with 4 GPM gas pressure washers. Just be aware that at lower flow rates, the outer edges of the cleaning path may not be as consistent.

For washers producing 4 or more GPM, this cleaner will deliver outstanding results. If your washer produces less than 4 GPM, consider stepping down to a 20 inch model like the WOJET or MEKOH for better nozzle rotation consistency.

Connection and Setup

The JANZ 24 inch uses a 3/8 inch QC inlet and includes two hose adapters for compatibility with different pressure washer setups. The adapters ensure you can connect to most gas pressure washers without purchasing additional hardware. The inlet fitting is brass for durability and corrosion resistance.

Assembly is straightforward: attach the handle, connect the castors if not pre-installed, and snap on your pressure washer hose. The cleaner arrives mostly assembled, and setup took me about 10 minutes from unboxing to first use.

Buying Guide: How to Choose the Best Pressure Washer Surface Cleaner

Choosing the right surface cleaner attachment comes down to matching the cleaner to your pressure washer and your cleaning needs. Here is everything I have learned from testing these attachments to help you make the right choice.

Understanding PSI and GPM Requirements

PSI (pounds per square inch) measures the force of the water coming out of your pressure washer. GPM (gallons per minute) measures the volume of water flowing through the system. For surface cleaners, GPM is actually more important than PSI because it determines whether the spray bar will rotate fast enough to clean evenly.

Most surface cleaners require a minimum of 2000 PSI and 1.5 to 2.0 GPM to function properly. If your pressure washer does not meet these minimums, the nozzles will not spin fast enough and you will get streaky, incomplete cleaning. Always check the manufacturer’s PSI and GPM compatibility range before buying.

The 4-Inch-per-GPM Rule for Sizing

This is the golden rule that professional pressure washers use, and it is something most buying guides skip entirely. For every 1 GPM your pressure washer produces, you can effectively power 4 inches of surface cleaner width. Here is how that breaks down:

A 2 GPM washer works best with an 8 to 11 inch cleaner. A 2.5 GPM washer pairs well with a 12 to 14 inch cleaner. A 3 GPM washer can handle a 14 to 16 inch cleaner. A 4 GPM washer can drive a 16 to 20 inch cleaner effectively. For anything above 5 GPM, a 20 to 24 inch cleaner becomes practical.

This rule explains why some users report poor results with large surface cleaners on modest pressure washers. If you pair a 24 inch cleaner with a 2 GPM electric washer, the spray bar simply cannot rotate fast enough to deliver consistent cleaning.

Gas vs Electric Pressure Washer Compatibility

Gas pressure washers typically produce higher PSI and GPM, making them compatible with larger surface cleaners. Most gas units in the 2800 to 4000 PSI range with 2.5 to 4.0 GPM can drive 14 to 20 inch cleaners effectively. The Westinghouse 16.5 inch and Simpson 16.5 inch in this roundup are excellent choices for gas washer owners.

Electric pressure washers generally produce lower PSI and GPM. If you own an electric unit rated under 2000 PSI or under 1.5 GPM, look for an 11 to 14 inch surface cleaner specifically designed for electric compatibility. The Karcher 15 inch and Hourleey 14 inch work well with electric washers that meet their minimum requirements.

Wheels vs Bristles: Which Is Better

Surface cleaners come with either wheels, a bristle ring, or both. Wheels allow the cleaner to glide smoothly across the surface, reducing fatigue and making it easier to maintain consistent speed. Models with four wheels like the WOJET and MEKOH offer the best maneuverability for large areas.

Bristle rings create a tighter seal against the surface, which reduces overspray and can improve cleaning on slightly uneven surfaces. However, bristles create more friction and can be tiring to push over long distances. For most homeowners, a wheeled model is the better choice.

Build Quality and Materials

Stainless steel housings offer the best durability and corrosion resistance. The Westinghouse, Hourleey, janz, Biswing, Simpson, WOJET, and JANZ models all feature stainless steel construction. Polymer housings like the MEKOH are lighter and less expensive but may not last as long with heavy use.

Look for sealed bearings in the swivel assembly, as this prevents water and debris from entering and causing premature wear. The WOJET’s fully sealed and pre-greased swivel is a good example of this feature done right. Brass fittings at connection points also indicate better quality than plastic alternatives.

How to Avoid Swirl Marks

Swirl marks are the circular patterns that sometimes appear after using a surface cleaner. They occur when the spray bar rotates unevenly or when the operator moves the cleaner too slowly. To prevent swirl marks, keep the cleaner moving at a steady walking pace and overlap each pass by about 25 percent.

Maintaining your nozzles is also critical. Clogged or worn nozzles create uneven spray patterns that lead to swirl marks. Clean your nozzles after each use and replace them when you notice a decline in cleaning performance. Using the correct cleaner size for your GPM also helps prevent the uneven rotation that causes swirl patterns.
