A wand held at a slightly different height on every pass leaves clean bands next to dirty ones, and driveway owners know that pattern by name: zebra striping. The fix is not more pressure, it is the right attachment. When we lined up the best pressure washer attachments for driveways, the difference between a mediocre wash and an even one came down to three things: a spinning spray arm, a nozzle height that never changes, and enough flow to keep that spinning arm turning.
A surface cleaner attachment is a disc-shaped head that bolts to the end of your wand or gun. Underneath, two nozzles sit at a fixed height above the concrete and spin fast, laying water down in a uniform overlapping pattern. No height drift means no stripes, and the splash skirt keeps the water and the overspray on the slab where you want it.
Most people reading this already own a washer, so the useful question is which head fits it. If you own an electric machine rated around 2,000 PSI, an undersized 11 to 14 inch deck is the right buy and a 20 inch steel deck is wasted money. Gas and diesel owners above 3,000 PSI can step up to a wider stainless steel deck. We cover the electric-first buying path in the matching section, and our related roundup on the best pressure washer surface cleaners goes deeper on deck sizing alone.

1. Karcher 15 inch Surface Cleaner for Even, Stripe-Free Results
Kärcher Pressure Washer 15″ Surface Cleaner Suitable for 2600 to 3200 PSI
- Dual spinning nozzles hold a fixed height
- Light deck at only 3.8 pounds
- Works with most washers from 2600 to 3200 PSI
- Splash skirt keeps you dry
- Includes an extension wand
- Leaves roughly a half inch gap at edges
- Plastic nut on the splash shield can loosen
- Not a vertical surface tool
This is the head I reach for first on a two-car driveway, and the reason is the 3.8 pound weight. On a wet slab with a spinning arm throwing water sideways, a heavy deck tires quickly, and a light deck lets you work longer without wrecking your grip or your afternoon.
The 15 inch cleaning path is the sweet spot. It is wide enough that overlapping passes cover a standard two-car slab in a handful of strokes, and narrow enough to steer around a parked car or a planter without fighting it. Two spinning nozzles hold a fixed height above the concrete, which is the entire anti-striping mechanism in one sentence.
Flow is the one number to watch. Rated up to 2.7 GPM and 3,200 PSI, it wants a machine in the 2,600 to 3,200 PSI band with real flow behind it. Pair it with a small electric unit and the arm will slow down, and a slow arm on a wet driveway leaves swirls rather than an even finish.
Reviewers report cutting cleaning time by more than half on driveways and patios, and the sealed bearing on the arm is a sensible detail for a tool that lives in a damp garage nine months of the year. The shroud and splash skirt also do real work: the water stays on the slab instead of soaking your ankles.
Who should buy the Karcher 15 inch?
Anyone with a washer in the 2,600 to 3,200 PSI range who cleans more than one driveway a year. Its light frame also makes it easier to handle on a slope or across a rolled curb, which matters if your driveway is not dead flat.
Where it falls short?
It cannot reach the last half inch against a wall or a curb, so you still need a wand or a turbo nozzle for edges. The plastic nut that holds the splash shield is also the part reviewers flag as loosening over time, so check it before a long job.
2. Greenworks 12 inch Surface Cleaner for Smaller Electric Washers
- Smallest and lightest deck here at 2.5 pounds
- Matches sub-2000 PSI electric machines
- 3 year warranty
- Brush skirt contains overspray
- Quick-connect 1/4 inch fitting
- Circular swirls if you move too slowly
- Not built for deep stains on neglected concrete
- Tight corners are awkward
This is the correct pick for a very common group of washer owners, which is anyone on a 1,800 to 2,000 PSI electric machine. At 2.5 pounds and a 12 inch path, it asks almost nothing of a small pump and still delivers the even finish a wand cannot.
The 2,000 PSI ceiling is not a marketing cap, it is a protection. On a driveway with oil, algae, or a season of road grime, a 12 inch deck at low pressure gives you the tool and the chemistry both a chance. The brush skirt keeps the dirty water inside the cleaning path.
Reviewers report cleaning two to three times faster than a wand, and they describe it as a maintenance tool rather than a restoration tool. That distinction matters: annual cleaning keeps a concrete slab in good shape, while neglected concrete with embedded oil needs more pressure than this deck can be given.
The 3 year warranty stands apart in this group, where 90 days and one year are more common. That is a meaningful signal on a spinning part that takes abuse from grit and dried debris.
Who should buy the Greenworks 12 inch?
Electric washer owners, first-car driveway owners, and anyone working on a patio or sidewalk rather than a full four-car slab. It also pairs well with the foam cannon listed later for the detergent pre-treatment pass.
Where it falls short?
Pushing it too slowly leaves faint circular patterns, which is a technique problem rather than a defect. It also struggles in tight corners, and its light frame is less stable on a high-flow gas machine than on the electric unit it is designed for.
3. LidoDola 14 inch Surface Cleaner for the Full Accessory Kit
LidoDola 14” Pressure Washer Surface Cleaner, Power Washer Accessory
- Stainless steel housing with heavy-duty bearing
- Weighted base resists lifting under pressure
- Four wheels roll over rolled curbs
- Inlet filter helps prevent clogs
- Heavy at 7.7 pounds
- Newer brand with a shorter track record
- Wants the upper half of its PSI range to shine
What separates this one is the box contents. Two extension wands, two replacement nozzles, O-rings, an inlet filter, thread seal tape, and a nozzle cleaner are all included, which removes the most common reason a new surface cleaner ends up unused.
The stainless steel shell and the weighted base both solve the same real problem: a deck that tries to lift or walk under pressure. At 7.7 pounds it is one of the heavier picks here, and on a sloped driveway that weight is an advantage rather than a burden.
Four universal wheels make the 14 inch path manageable, and the 1/4 inch quick-connect plug with an anti-clog inlet filter is a sensible pairing because the filter sits exactly where driveway grit tries to get in. The stated compatibility range of 2,000 to 4,000 PSI is broad and honest.
Reviewers call the feature set generous for the money and the streak-free result strong. The one consistent drawback in reviews is the weight on longer jobs, and the fact that you get less real estate on the slab per push than a wider deck would give you.
Who should buy the LidoDola 14 inch?
Owners of a 2,500 to 4,000 PSI washer who want a complete kit in one box and who value a stainless shell over a featherweight frame. It also suits people cleaning sloped or uneven slabs where stability beats portability.
Where it falls short?
At 7.7 pounds it is one of the heaviest units in this roundup, so it is a poor choice for a person who wants a light tool for a small patio. It also may need higher pressure to reach its best result, so a small electric washer will not unlock its full potential.
4. JANZ 14 inch Surface Cleaner for the Widest Compatibility Window
- Flow rated from 1.8 to 3.7 GPM
- Stainless steel housing and heavy-duty bearing
- Three spare tips plus two extension wands
- Built-in filter blocks impurity blockage
- Top connector can feel fragile
- Jets occasionally arrive blocked with machining debris
- Below 2000 PSI electric machines struggle
The 1.8 to 3.7 GPM window is the reason this deck suits so many machines. Most listings quote a pressure ceiling and stop, and that number tells you nothing about whether a small electric pump can keep the arm turning.
Reviewers report it working with smaller washers down around 1,750 PSI, which is unusual for a stainless steel 14 inch deck. The fixed nozzle height and dual spinning jets do the anti-striping work, and the four wheels let you push it across a rolled curb without lifting.
The attachment kit is unusually complete: two extension wands, two replaceable nozzles, three 0 degree spray tips, O-rings, an inlet filter, thread seal tape, and a nozzle cleaner. That spare tip set matters more than it sounds, because a driveway job will block a jet at some point.
Two things come up repeatedly in reviews. The top connector can feel slightly fragile, and jets occasionally arrive blocked with metal shavings from machining, which the included nozzle cleaner clears in a minute.
Who should buy the JANZ 14 inch?
Owners who are not certain how much flow their washer delivers, or who want one deck that covers a small electric unit today and a bigger gas machine later. The spare tips and wands also make it a good first purchase.
Where it falls short?
Below about 2,000 PSI the result depends heavily on your technique, and a couple of reviewers note that performance tracks the flow coming out of the washer more than the deck itself. The top connector is the part to watch for stress cracks over time.
5. Biswing 14 inch Surface Cleaner for Gas Washer Owners
- Brass and stainless fittings resist wear
- Handles 3200 PSI and above washers well
- Four wheels glide over rolled curbs
- Two 15 inch extension wands included
- Handle is short for taller users
- Fine thread connection may need an adapter
- Splits flow between two nozzles
For a gas washer pushing 3,200 PSI and above, this is the deck that makes sense. It handles high pressure without complaint, and the stainless steel and brass fittings are the right materials for a tool that sees water at temperature and grit at the same time.
The stated operating window runs from 2,000 to 4,000 PSI and 1.8 to 3.7 GPM, which lines up with most mid and upper gas machines. A built-in filter keeps driveway grit out of the spray path, and four wheels handle a rolled curb without dragging.
Two 15 inch extension wands, two replacement nozzles, thread seal tape, O-rings, and a nozzle cleaner are all included. Reviewers consistently frame this as a maintenance cleaning tool that cuts job time roughly in half, not a restoration tool for concrete that has gone untouched for years.
It is worth being clear about that limit. On badly neglected concrete with no pre-treatment, reviewers note the result falls short, and the chemistry step matters more here than on any other pick in the list.
Who should buy the Biswing 14 inch?
Owners of a gas pressure washer in the 3,000 PSI class and up who clean large slabs and want a frame that survives high pressure. It is also a strong option if you are buying your first surface cleaner and want spare parts included.
Where it falls short?
The handle length is short, and reviewers with more height ask for a longer one after a long job. Some pressure washer guns use a fine thread that needs an adapter, so check the coupler on your gun before you order.
6. Tool Daily 14 inch Surface Cleaner for High-Output Machines
Tool Daily 14” Pressure Washer Surface Cleaner with 4 Wheels, 4000 PSI
- Stainless steel build with four wheels
- Includes two 15 inch wands and spare nozzles
- Also made in wider sizes for larger slabs
- Splash skirt keeps the user dry
- Best results need 3000 PSI and 3 GPM or more
- Some pieces arrive with a misaligned spray arm
- Handle quality varies from one to another
This deck is built for the high end of the range. Reviewers are direct that it wants 3,000 PSI and 3 GPM or more to show what it can do, which puts it in a very different league from the small electric-friendly units above it.
The stainless steel housing and four wheels are the right combination for big work. Pushing a 14 inch deck across a four-car slab at speed on a high-flow machine is where the frame earns its weight, and the splash skirt keeps you out of the runoff.
Two 15 inch extension wands and two replacement nozzles are included, and the same line is made in 16.5, 18, 20, and 24 inch sizes. If your driveway is long and your washer is genuinely powerful, the wider versions are the ones to look at next.
Who should buy the Tool Daily 14 inch?
Owners of a 3,000 PSI plus machine who want a stainless deck with wheels and a full accessory kit. The wider sizes in the same line suit anyone cleaning more than a two-car driveway at a time.
Where it falls short?
It is a poor match for a small electric washer, where the result falls well short of what the deck suggests. Reviewers also report spray arm misalignment on some pieces and handle quality that varies from one to another, so inspect it on arrival.
7. Hourleey 14 inch Surface Cleaner as the Most Versatile
- Stainless steel shell with a heavy-duty bearing
- Four 360 degree casters glide smoothly
- Full accessory kit included
- Works well from 2500 PSI up
- Struggles with washers under 2000 PSI
- Swirl marks appear if you push too fast
- Works better pulling than pushing
This is the value entry in the roundup, and the casters are the detail that separates it from cheaper plastic decks. Ball bearing casters with 360 degree rotation make a 14 inch stainless head glide across a flat slab instead of digging in.
The manufacturer suggests 2,500 PSI or above for the best result, and reviewers with machines in that range report large time savings. Below 2,000 PSI the deck struggles, which is a fair description of a tool that is being asked for more than the pump can give.
Two extension wands, replacement nozzles, O-rings, thread seal tape, and a nozzle cleaner are all included. The stainless steel shell carries enough weight to resist lifting under pressure, which is a real problem with light plastic decks on a wet surface.
Technique matters more here than with the heavier picks. Reviewers note that slow movement gives the best result, and that it works better pulled than pushed, both of which are adjustments rather than faults.
Who should buy the Hourleey 14 inch?
Owners with a 2,500 to 3,200 PSI washer who want a wheeled stainless deck without paying for a premium brand. It suits maintenance cleaning on an already-kept driveway rather than a first-time restoration.
Where it falls short?
It does not suit low-PSI electric machines, where reviewers report weak results. Move too quickly and swirl marks show up, so this is a tool that rewards a slower, more deliberate pace than the lighter decks do.
8. Tool Daily Foam Cannon for the Detergent Pre-Treatment Pass
Tool Daily Foam Cannon with 1/4 Inch Quick Connector, 1 Liter, 5 Pressure Washer Nozzle Tips
- Adjustable knob controls foam thickness
- Five tips cover 0 to 65 degrees
- Quick-connect swaps on in seconds
- Works for driveway pre-treatment and cars
- Not for a garden hose or faucet
- Plastic bottle can collapse when empty
- Coarse adjustment knob
A surface cleaner moves dirt, it does not lift it. The detergent pass is where driveway cleaning is actually won, and this foam cannon is the most direct way to do that step properly on a large slab.
Fill the 1 liter tank with warm water and your degreaser, snap it onto any standard 1/4 inch quick connect wand, and turn the top knob to set the foam thickness. The nozzle on the end adjusts the spray pattern, and the included tips cover 0, 15, 25, 40, and 65 degrees.
Working pressure is rated 1,000 to 3,000 PSI, which covers essentially every residential washer. Apply the foam, let it dwell for 10 to 15 minutes, and then run the surface cleaner over the same area while the chemistry is still working.
Reviewers note the plastic bottle can collapse as it empties and that the adjustment knob is coarse, giving you either a lot of soap or almost none. Drilling a small vent hole in the cap is the standard fix and takes a minute.
Who should buy the foam cannon?
Anyone with algae, mildew, oil, or tire marks on a driveway, and anyone who washes vehicles. The 1 liter tank covers a full pass on a full-size vehicle and is quick to refill.
Where it falls short?
It will not run off a garden hose or a faucet, only a pressure washer with a 1/4 inch quick connect. Expect a coarse adjustment knob and expect to drill a vent hole in the bottle once it starts to flex.
9. AURORA CAR Turbo Nozzle for Edges, Corners, and Oil Stains
AURORA CAR Pressure Washer Tips Turbo Nozzle Pressure Washer 4000 PSI Max
- Ceramic core resists wear
- Brass and stainless construction
- Snaps onto a 1/4 inch quick connect
- Handles concrete
- brick
- rust and heavy grime
- Not for wood or painted surfaces
- Noisy with noticeable vibration
- Prefers 4 GPM or more to run well
Every surface cleaner leaves a gap at the edges, and that gap is where a turbo nozzle earns its place. The rotating action combines a concentrated punch with wider coverage, which is what makes it the right tool for a drip line against a curb and a stubborn oil spot.
The build is the surprise here. A ceramic core inside a brass and stainless steel body resists the wear that chews through cheap plastic nozzles, and the 1/4 inch quick connect means it fits the same wand as the surface cleaner you already own.
It is rated from 1,000 to 4,000 PSI with a 4.0 orifice and 4.0 GPM flow rating, so it wants a machine with real flow. Reviewers report cutting cleaning time roughly in half on driveways, siding, and heavy grime, and note it works on rust and metal as well as concrete.
Two cautions come straight from owners. It is not a tool for wood or painted surfaces, and it is loud with real vibration, so ear protection is sensible on a long session.
Who should buy the turbo nozzle?
Anyone cleaning driveway edges, corners, wheel wells, and oil or rust stains on concrete or brick. It pairs naturally with a surface cleaner, covering exactly the zones the disc cannot reach.
Where it falls short?
On a small electric machine the rotation slows and the impact drops, so it is a weaker partner with low-flow washers. It also wears out faster than a metal nozzle, and some can stick before the ball seats on first use.
10. Greenworks Soap Applicator for Low-Flow Washers
Greenworks High Pressure Soap Applicator Universal Pressure Washer Attachment
- Works with small 1.4 GPM washers
- On and off dial without disconnecting
- Keeps aggressive cleaner out of the washer tank
- Universal 1/4 inch connection
- Produces thinner soap than a foam cannon
- Plastic bottle can collapse when empty
- Dial is coarse
This is the detergent option for the smallest machines. Rated for up to 1.4 GPM and 3,000 PSI, it works on compact electric washers where a heavy foam cannon can starve the pump and produce nothing but air.
The easy on and off dial means you can switch between soap and rinse without breaking the connection, which saves a surprising amount of time over a full driveway. The 1 liter tank holds enough for a full pass on a two-car slab.
Who should buy the soap applicator?
Owners of a compact electric washer who want to pre-treat a driveway or wash a car without a second piece of equipment. It is also a clean way to keep harsh deck cleaner out of the pressure washer reservoir.
Where it falls short?
It makes thinner soap than a foam cannon, so coverage takes longer to build. The bottle can collapse as it drains, and the dilution dial moves in coarse steps rather than small ones.
The Attachment Types You Actually Need for a Driveway
Most driveways need two attachments, not ten. The surface cleaner handles the flat field, and something in your hand handles the edges.
Surface cleaner attachment
A disc with a spinning arm and a brush or splash skirt. This is the tool that eliminates zebra striping across the main slab, and it is where seven of our ten picks sit. Our dedicated pressure washer surface cleaner roundup compares deck widths in more detail.
Turbo nozzle
A rotating jet that combines a concentrated punch with a wider fan. It covers the half inch gap at curbs, works corners and edges, and gets into an oil stain or a patch of algae quickly. Keep it away from wood, painted surfaces, and anything sealed.
Soap applicator and foam cannon
Both draw detergent from a tank through your washer pump. A foam cannon makes thick clinging foam for a long dwell time, while a soap applicator is lighter and works on small low-flow machines. Either one belongs on the driveway before the surface cleaner does.
Extension wand
Several of the picks above include 15 inch wands, which is what lets you stand up instead of crouching. A longer wand also helps on a deep four-car driveway where you would otherwise be walking backward the whole job.
Match the Attachment to Your Pressure Washer
Two numbers decide whether an attachment works: pressure and flow. PSI is the stripping force, GPM is the water volume that carries the loosened dirt away, and a spinning arm needs both.
The working rule of thumb is 4 to 5 inches of deck per 1 GPM of your washer. A 2.0 GPM electric washer therefore wants a 10 to 12 inch deck, and a 4.0 GPM gas machine can justify a 16 to 20 inch one. Pair a wide steel deck with a small pump and the arm stalls, which is the streaky result people blame on the attachment.
On connectors, nearly everything here uses a 1/4 inch quick connect, which snaps to a standard gun or wand in seconds. A minority of brands use a proprietary fitting, and some guns use a fine thread that needs an adapter, so check the coupler on your gun before you buy.
Matching by washer class, in plain terms: an electric unit from 1,800 to 2,000 PSI wants an 11 to 12 inch deck. A mid-range gas machine from 2,500 to 3,000 PSI pairs with a 14 to 15 inch stainless deck. Above 3,500 PSI you can step up to 16 inches and wider, and that is the only situation where a larger deck actually pays for itself.
What PSI Is Safe for Your Driveway Surface?
Concrete is strong, but it is not indestructible. A cream coat of surface paste sits on top of the slab, and too much pressure will etch it and leave permanent pitting.
For fully cured standard concrete, 2,500 to 3,000 PSI is the right working range. Brick and pavers want less, around 1,500 to 2,500 PSI, because higher pressure blows polymeric joint sand out of the seams and leaves a mess to repair. Asphalt is softer still at 1,200 to 2,000 PSI, and stamped or sealed concrete sits in the same range because a sealer will not tolerate more.
New concrete is the exception. It reaches design strength at about 28 days but keeps hardening for a year, and washing it early is the fastest way to ruin it. If the pour is recent, wait.
On nozzle color, a 25 degree green tip is the standard choice for cured concrete, and a 40 degree white tip is the gentler option for asphalt, pavers, and sealed surfaces. The 0 degree red tip can etch concrete and has no place near a driveway you care about.
How to Use a Surface Cleaner on a Driveway?
The sequence matters more than the attachment. A spinning arm on a dirty slab grinds dirt into the concrete instead of lifting it.
Clear the slab. Sweep or blow off leaves, gravel, and twigs, and move planters and vehicles out of the way.
Pre-treat with a concrete cleaner or degreaser using the foam cannon or soap applicator.
Let it dwell for 10 to 15 minutes. Keep the surface wet, because a dry slab plus a spinning arm is how you etch concrete.
Pre-rinse with a 40 degree white tip if the dirt is heavy enough to mask the surface.
Run the surface cleaner in slow, overlapping passes, starting at the high end of the surface and working downhill.
Work in strips the width of the deck, overlapping each pass slightly so no seam is left behind.
Rinse from the top down with a wand, then let the slab dry fully before anyone drives on it.
Seal once dry, and keep vehicles off the new sealer until it has cured.
For black algae and mildew streaks that survive the first pass, a sodium hypochlorite solution at 3 to 6 percent applied after cleaning and left to dwell overnight is the standard follow-up. Rinse thoroughly the next morning.
While you have the slab wet, it is worth checking where the water is going. Poor drainage leaves standing water that finds the same weak spots every winter, and our guide to channel drain systems for driveways covers the options if pooling is a recurring problem.
Attachment Problems and Fixes
These are the five faults that come up again and again in pressure washing forums, and none of them mean you need a new attachment.
My surface cleaner is losing pressure
This is the most common thread on r/pressurewashing, and the diagnosis is a three-step check. First, test the spray without the spinning attachment attached. Then remove the spinning hub from its bearing and run it again. If the spray is strong with the hub off, the restriction is in the hub or its jets, and a rinse through the included nozzle cleaner usually restores full pressure.
The rotating arm stalls or stops spinning
An arm stops when it meets dried debris, a rough aggregate surface, or a hard edge. Clear the surface before you start, keep the slab wet, and lift the deck rather than forcing it forward when it snags. A stall leaves an uneven, streaky patch that you can fix with another pass once you know where it happened.
Jets are blocked or the spray is weak on one side
Driveway grit gets into the jets, and some decks arrive with machining debris in them. Every pick in this roundup that has a stainless steel deck includes a nozzle cleaner for exactly this. Pull the nozzles, soak them, clear the orifices, and recheck the pattern before you judge the attachment.
It will not connect to my gun
Almost everything here is a 1/4 inch quick connect, but a minority of guns use a fine thread or a proprietary fitting. Check the coupler on your gun first, and keep a short adapter hose in the garage, because swapping guns mid-project is a nuisance.
It leaves swirls instead of an even finish
Swirls come from moving too slowly or from a small washer that cannot keep the arm spinning fast enough. Speed up slightly, and if the machine is under 2,000 PSI, drop to a smaller deck where the flow can keep up.
Attachment Care and Storage
Rinse the deck and the skirt after every job, before the grit dries into the brush ring. Dry it standing on its wheels rather than flat, so water does not sit in the housing.
Store it off the concrete floor in a dry garage, and give the hub a spray of lubricant before a long layoff. If your washer has hot water capability, check the temperature rating of the attachment before you use it, because plastic housings do not tolerate near-boiling water.
Frequently Asked Questions
What pressure washer nozzle is best for a driveway?
A 25 degree green tip is the standard choice for fully cured concrete, and a 40 degree white tip is the safer pick for asphalt, pavers, and sealed or stamped concrete. A 0 degree red tip etches concrete and should never be used on a driveway. For the main field of the slab, a surface cleaner attachment beats any tip because it holds a fixed height.
Is 2500 PSI enough to clean a driveway?
Yes, for fully cured standard concrete, 2,500 PSI with a 25 degree nozzle or a surface cleaner attachment is enough to lift grime, algae, and tire marks. It is too much for pavers and brick, where it can blow polymeric joint sand out of the seams, and it is not appropriate for new concrete that has not finished curing.
What is a good PSI for a pressure washer for a driveway?
For fully cured standard concrete, 2,500 to 3,000 PSI is the right working range. Brick and pavers want 1,500 to 2,500 PSI, asphalt wants 1,200 to 2,000 PSI, and stamped or sealed concrete stays in the 1,500 to 2,000 PSI band. Newly poured concrete should not be washed until it has cured for months, not days.
Do pressure washer surface cleaners actually work?
Yes. A surface cleaner holds two spinning nozzles at a fixed height above the slab, which removes the clean and dirty banding that gives a wand its stripes, contains overspray, and uses less water than a nozzle alone. The one caveat is matching minimum flow to deck width, roughly 4 to 5 inches of deck per 1 GPM of washer flow.
Can I use a pressure washer surface cleaner on pavers?
Yes, but keep the pressure down to 1,500 to 2,500 PSI and use a wide 40 degree fan rather than a concentrated jet. Running too much pressure through the joints will wash polymeric sand out of the seams and leave you with a resanding job. Work in the direction of the joints and rinse the sand back into place as you go.
Will a surface cleaner attachment work with an electric pressure washer?
Yes, but only with an undersized deck. An electric washer rated 1,800 to 2,000 PSI pairs correctly with an 11 to 12 inch surface cleaner. A 15 inch or 20 inch stainless steel deck needs a gas machine with real flow, because a small pump cannot keep the spray arm spinning fast enough to clean evenly.
The Bottom Line on Driveway Attachments
Most driveways need two things and not ten: a surface cleaner for the flat field and a turbo nozzle for the edges. On a washer in the 2,600 to 3,200 PSI range, the Karcher 15 inch is the one to buy first. Electric washer owners should step down to the Greenworks 12 inch, and anyone who wants a complete kit in one box will be well served by the JANZ 14 inch.
Match the deck to your flow, keep the surface wet while you work, and let the chemistry do the lifting before the arm does. Check the current details for the picks above, then start at the top of the driveway and work your way down.
