A pressure washer surface cleaner is a round, rotating-arm attachment that sits flat on the ground and cleans in even, overlapping circles, so pavers and driveways come up streak-free in a fraction of the time a bare wand takes. If you’re sorting out pressure washer hire in Perth for a grimy driveway or a mossy paved patio, adding a surface cleaner is the single biggest upgrade you can make to the finished result.
This guide explains how a surface cleaner works, which surfaces suit it, what pressure washer you need to run one, and the exact steps to clean pavers and driveways without blasting out the joints or leaving stripes.
What Is a Surface Cleaner and How Does It Work?
A surface cleaner is a circular housing that attaches to the end of your pressure washer lance. Inside the housing, a spinning bar with two or more nozzles blasts the surface, while the cover keeps the spray contained. Because the nozzles rotate at a fixed height above the ground, every part of the surface gets the same amount of cleaning force.
Most residential surface cleaners are roughly 30cm to 50cm across, so each pass covers a much wider strip than a single fan nozzle. The cover also cuts splashback, which keeps dirty water off your shoes, walls and garden beds.
Surface Cleaner vs Bare Wand
| Factor | Surface Cleaner | Bare Wand |
|---|---|---|
| Finish | Even, streak-free | Prone to stripes and “tiger marks” |
| Speed on large areas | Much faster | Slow and tiring |
| Splashback | Contained under the cover | Sprays everywhere |
| Control on edges and steps | Limited | Excellent |
| Risk of gouging the surface | Lower | Higher if held too close |
In practice you’ll use both: the surface cleaner for flat open areas, and the wand for edges, steps and tight corners.
Which Surfaces Suit a Surface Cleaner?
Surface cleaners are made for flat, hard, horizontal surfaces. They work well on:
- Concrete driveways, paths and garage floors
- Concrete, clay and limestone pavers
- Exposed aggregate (use a gentler approach so you don’t loosen the stones)
- Brick paving and flat retaining wall tops
Avoid using one on timber decks, painted surfaces, soft stone, loose gravel or anything with damaged, crumbling joints. If you’re unsure about a particular surface, test a small hidden patch first.
What Pressure Washer Do You Need to Run a Surface Cleaner?
A surface cleaner needs a pressure washer with enough water flow, not just high pressure. A small, light-duty machine will run the attachment slowly and leave you with a patchy clean. For driveways and pavers, a medium-duty machine is the practical starting point, which our size guide puts at roughly 2000 to 3000 PSI.

Petrol or Electric?
Petrol pressure washers are the usual choice for large driveways because they deliver more flow and don’t need a power outlet. Electric machines are quieter and fine for smaller paved areas. Our buyer’s guide breaks down the differences in more detail.

Check Compatibility Before You Book
Surface cleaners connect to the lance with a specific fitting, and they have a recommended pressure and flow range. When you book, tell our team you want to use a surface cleaner so we can match the machine and attachment properly. Surface cleaner availability changes, so ask about it up front rather than assuming it’s included.
Before You Start: Prep Checklist
A few minutes of prep makes the job quicker and the result better.
- Sweep or blow off loose dirt, leaves and debris.
- Move cars, furniture, pots and toys off the area.
- Cover or protect nearby plants, and close windows and doors close to the work area.
- Check the pavers for loose, cracked or sunken units and the joints for gaps. Heavy cleaning can make weak spots worse.
- Pre-wet the surface lightly and apply a suitable detergent to oil, algae or stubborn stains, following the label directions.
- Connect the machine to a clean water supply and check hoses and fittings for leaks.
Step-by-Step: How to Clean Pavers and Driveways with a Surface Cleaner
- Do a test patch. Pick a hidden corner and clean a small square to check the pressure won’t damage the surface or strip the joint sand.
- Start at the highest point. Work downhill so dirty water runs away from the clean area.
- Hold the cleaner flat and move slowly. Keep the housing resting on the surface and walk at a steady pace. Rushing leaves lines.
- Overlap each pass. Overlap by a few centimetres so you don’t leave stripes.
- Work in sections. Clean one section fully, then move on, rather than skipping around.
- Switch to the wand for edges. Use the bare wand with a wide fan nozzle for steps, edges and tight corners, keeping the nozzle at a safe distance.
- Rinse and inspect. Rinse the whole area, let it dry, and check for missed patches or remaining stains before packing up.

Protecting Paver Joints
Joint sand locks pavers together and keeps weeds out, and a pressure washer can blast it out if you’re not careful. Keep the surface cleaner moving, use a lower pressure setting on pavers than you would on plain concrete, and never point the wand straight down into the joints.
After cleaning, check the joints. If sand has washed out, sweep fresh paver or jointing sand across the surface until the gaps are full, then brush off the excess. If the pavers have shifted or sunk, they may need re-bedding, which is a bigger job than a clean.
Should You Seal After Cleaning?
Sealing can make pavers easier to clean in future and can deepen their colour, but it isn’t compulsory. If you plan to seal, let the surface dry completely first, which can take a day or more depending on the weather, and follow the sealer manufacturer’s instructions.
Common Perth Stains and What Pressure Washing Can Fix
Algae, Moss and Mould
Shaded, damp areas grow green and black growth. A surface cleaner with a suitable detergent removes most of it, and it clears the slippery film that makes pavers dangerous when wet.
Oil and Grease
Fresh oil lifts more easily than old oil. Treat the stain with a degreaser before you pressure wash, then repeat if needed. Old, deeply soaked stains may never disappear completely.
Rust Stains From Bore Water
Orange rust marks from reticulation or bore water are common on Perth driveways and pavers. Pressure washing alone often only fades them, so a dedicated rust remover suited to your surface usually does the real work. Always test first.
White Powdery Marks (Efflorescence)
New pavers and concrete can develop white, powdery salt deposits. These don’t respond well to water alone and typically need a product designed for efflorescence.
How Long Does the Job Take?
A single-car driveway can often be cleaned in a few hours with a surface cleaner, while a larger driveway plus paved patio and paths may take a full day once you include prep, detergent dwell time and rinsing. Quinns Rocks Tool Hire offers hire periods from 24 hours through to long-term, so you can plan around the weather.

Safety Tips for Using a Pressure Washer
High-pressure water can cut skin, so treat the lance like a power tool.
- Never point the nozzle at people, pets or your own feet.
- Wear closed shoes with good grip, eye protection and hearing protection, particularly with petrol machines.
- Wet pavers get slippery, so watch your footing, especially on slopes and steps.
- Run petrol machines outdoors only, where exhaust fumes can’t build up.
- Keep electric leads and connections dry and away from standing water.
- Don’t use the machine from a ladder, and never leave it running unattended.

Keep Runoff Out of the Stormwater Drain
Dirty wash water, detergent and oil can end up in stormwater drains, which lead to local waterways. Wherever you can, let wash water soak into a lawn or garden bed, or collect it, rather than letting it run onto the street. Choose a biodegradable detergent and avoid washing heavy oil or chemical residues straight down the drain.
Common Mistakes When Using a Surface Cleaner
- Using too much pressure on pavers. It strips joint sand and can roughen the surface.
- Moving too fast. Speed leaves stripes and missed patches.
- Skipping the detergent on algae and oil. Pressure alone won’t lift everything.
- Hiring an underpowered machine. Low flow means a slow, patchy job.
- Cleaning in direct midday sun. Detergent can dry on the surface before you rinse it.
- Forgetting the joints. Check and refill joint sand once the pavers are dry.
Pressure Washer Hire vs Buying vs Hiring a Cleaning Service
Most households only deep clean their driveway and pavers once or twice a year, which makes buying a quality machine and surface cleaner hard to justify. Hiring gives you a powerful machine and the right attachment for just the days you need it. A professional cleaning service is an option if you’d rather not do the work, but for a typical home, hiring equipment and doing it yourself is often the cheaper route.

Frequently Asked Questions
1. What is a pressure washer surface cleaner?
It’s a circular attachment with rotating nozzles that sits flat on the ground and cleans flat surfaces like driveways and pavers evenly and quickly, without the streaks a bare wand can leave.
2. Can I use a surface cleaner on pavers?
Yes, but use a lower pressure than you would on plain concrete, test a hidden patch first, and check the joint sand afterwards.
3. What size pressure washer do I need for a driveway?
A medium-duty machine, roughly 2000 to 3000 PSI, suits most driveways. Make sure it has enough water flow to run a surface cleaner properly.
4. Will a pressure washer remove oil stains from my driveway?
Fresh oil often lifts well with a degreaser and pressure washing. Old, soaked-in stains may fade but not disappear fully.
