An electric pressure washer can make a big difference when it comes to cleaning around the home. Cars, outdoor furniture, decks, patios, paths and driveways can all collect dirt, mud, mould and grime that are difficult to remove with a standard garden hose.
The tricky part is choosing the right machine. A pressure washer with a higher PSI isn't automatically the best choice, and buying a machine that's too small for the jobs you have in mind can leave you frustrated.
In this guide, we'll look at what to consider when choosing an electric pressure washer in Australia, including pressure, water flow, motor type, pump construction, accessories and the type of cleaning you actually plan to do.
Electric Pressure Washer Cleaning Guide
If you're looking for a quick answer, start with the type of cleaning you expect to do most often.
| Cleaning Task |
Recommended Bar |
Recommended PSI |
Recommended Machine Type |
| Cars |
70–120 bar |
1,000–1,700 PSI |
Compact electric |
| Outdoor Furniture |
70–120 bar |
1,000–1,700 PSI |
Compact to mid-range electric |
| Timber Decking |
70–145 bar |
1,000–2,100 PSI |
Mid-range electric |
| Patios |
125–145 bar |
1,800–2,100 PSI |
Mid-range electric |
| Driveways |
125–160+ bar |
1,800–2,300+ PSI |
Higher-performance electric |
| Concrete |
125–160+ bar |
1,800–2,300+ PSI |
Higher-performance electric with suitable nozzle |
These are general starting points rather than strict rules. The right pressure also depends on the material you're cleaning, the nozzle you're using and how close you hold the lance to the surface. Softer settings are generally more suitable for delicate surfaces such as timber, painted finishes and outdoor furniture, while harder surfaces like concrete and masonry can usually handle higher pressure. Always start with a lower setting and test on an inconspicuous area before cleaning the entire surface.
What Is an Electric Pressure Washer?
An electric pressure washer uses an electric motor to drive a pump, which forces water through a small nozzle at much higher pressure than a standard garden hose.
The result is a concentrated stream of water that can loosen and remove dirt, mud, grime and other build-up from outdoor surfaces.
Electric models are particularly popular for household cleaning because they're straightforward to start, don't require petrol and generally need less routine maintenance than petrol-powered machines.
How Does an Electric Pressure Washer Work?
The process is fairly simple.
Water enters the machine from your garden hose. The electric motor powers the high-pressure pump, which pressurises the water before sending it through the spray gun and nozzle.
Changing the nozzle or spray setting changes how that water hits the surface. A wider spray is useful for covering larger or more delicate areas, while a narrower spray concentrates the cleaning force in a smaller area.
Some machines also allow detergent to be applied through the pressure washer, which can help with jobs such as washing vehicles or removing built-up grime.
Benefits Over Traditional Cleaning Methods
A pressure washer can clean much faster than a garden hose alone because the water is delivered at significantly higher pressure.
They're useful for everything from washing the family car to cleaning outdoor furniture, patios and hard surfaces around the property.
Electric pressure washers also have a few practical advantages for homeowners:
- Easy push-button or trigger starting
- No petrol to mix, store or refuel
- Generally lower routine maintenance
- Lower noise than many petrol models
- Compact options are easy to store
- Suitable for a wide range of household cleaning jobs
The key is choosing a machine that matches the work you're actually going to do.
What Can You Clean with an Electric Pressure Washer?
Electric pressure washers can handle a surprisingly wide range of jobs, but not every surface should be treated with the same amount of pressure.
Start with a wider spray and lower pressure where possible, then increase the cleaning power if necessary. This is particularly important on painted surfaces, timber and vehicles, where excessive pressure can cause damage.
| Surface |
Recommended Pressure |
Safe to Clean? |
| Cars |
1,000–1,700 PSI |
Yes, with a suitable nozzle and setting |
| Motorcycles |
1,000–1,700 PSI |
Yes, with care around sensitive components |
| Bicycles |
1,000–1,700 PSI |
Yes, using a gentle setting |
| Patios |
1,800–2,100 PSI |
Yes |
| Decking |
1,000–2,100 PSI |
Yes, but use lower pressure on timber |
| Driveways |
1,800–2,300+ PSI |
Yes |
| Concrete |
1,800–2,300+ PSI |
Yes |
| Outdoor Furniture |
1,000–1,700 PSI |
Yes, depending on material |
| Fences |
1,000–2,100 PSI |
Yes, with care on timber and painted surfaces |
| Garden Tools |
1,000–1,700 PSI |
Yes, avoiding electrical components |
The pressure figures are useful as a guide, but don't treat them as a target you always need to reach. Using the highest possible setting isn't the goal. The goal is to remove the dirt without damaging the surface underneath.
Electric vs Petrol Pressure Washer: Which One Should You Choose?
Electric vs Petrol Pressure Washer: Which One Should You Choose?
Choosing between an electric and petrol pressure washer depends on the type of cleaning you need to do.
Electric pressure washers are generally convenient for household cleaning, including cars, outdoor furniture, patios and paths. Petrol models offer greater freedom of movement and are worth considering for more demanding cleaning tasks or locations without convenient access to electricity.
If you're unsure which option is right for your needs, read our guide to [Electric vs Petrol Pressure Washers](INSERT-LINK-HERE) for a more detailed comparison.
For this guide, we'll focus on choosing the right electric pressure washer for your home or property.
8 Most Important Things to Consider Before Buying an Electric Pressure Washer
There's more to choosing a pressure washer than looking at the biggest PSI number on the box. Pressure, water flow, the motor, pump, hose and accessories all affect how the machine performs.
Here are eight things worth checking before you buy.
1. Choose the Right Pressure (Bar & PSI) for Your Cleaning Tasks
Pressure is commonly shown in PSI (pounds per square inch) or bar.
As a rough conversion, 1 bar is approximately 14.5 PSI.
Higher pressure can help remove tougher dirt, but more isn't always better. Using excessive pressure on a car, painted surface or timber deck can cause damage.
As a general guide:
-
1,000–1,700 PSI: Cars, bikes, garden tools and lighter cleaning.
-
1,000–2,100 PSI: Timber decking and fences, using lower pressure on delicate surfaces.
-
1,800–2,100 PSI: Patios and general outdoor cleaning.
-
1,800–2,300+ PSI: Driveways, concrete and more demanding hard-surface cleaning
Many domestic electric pressure washers are designed to handle everyday cleaning tasks around the home, including vehicles, outdoor furniture, pathways and garden equipment. The pressure you need will depend on the type of surface and the level of dirt or grime you're removing. For more delicate surfaces, choosing the right nozzle and maintaining a suitable distance can help prevent damage.
When comparing machines, don't simply choose the one with the highest pressure rating. Consider the surfaces you'll be cleaning, the machine's water flow rate and whether it offers suitable nozzle options and accessories for different tasks. Having the right balance of pressure and control is often more important than choosing the most powerful machine.
2. Compare Water Flow Rate for Faster and More Efficient Cleaning
Pressure gets most of the attention, but water flow rate matters too.
Flow rate tells you how much water the machine can deliver, usually measured in litres per minute (L/min) or litres per hour (L/h).
A higher flow rate can help move loosened dirt away from the surface more quickly. That's one reason two machines with similar PSI figures can still feel quite different when you're using them.
When comparing STIHL pressure washers, look at both the maximum pressure and water flow rate to understand the machine's overall cleaning performance. STIHL offers different electric pressure washer models designed for a range of household and outdoor cleaning tasks, so consider the specifications of each model alongside the type of work you regularly undertake.
For lighter household cleaning, a lower flow rate may be sufficient for everyday tasks. If you're regularly cleaning larger areas, a machine with a higher water flow rate can help move loosened dirt and debris away more efficiently. Always compare the manufacturer's specifications and consider the cleaning tasks you need the machine to handle.
The important thing is to look at pressure and flow together, rather than choosing a machine based on PSI alone.
3. Choose the Right Motor Type for Better Performance and Longer Life
The motor is one of the main components that determines how an electric pressure washer performs.
You'll commonly come across universal motors and induction motors.
Universal motors are often found in more compact and affordable machines. They're useful for occasional household cleaning where keeping the machine light and easy to handle is a priority.
Induction motors are generally associated with larger, heavier-duty electric pressure washers. They tend to run more quietly and are designed for longer service life.
For example, the STIHL RE 110 PLUS uses an induction motor and aluminium high-pressure pump, while the RE 125 X also combines an induction motor with an aluminium pump.
If you only pull the pressure washer out a few times a year, you may not need to spend more on a heavy-duty motor. If you're using it regularly, the extra durability can be worth considering.
4. Check the Pump Material for Long-Term Reliability
The pump is another component worth paying attention to.
Pressure washers may use composite, aluminium or brass pump components, depending on the machine and price range.
Composite pumps can keep the machine lighter and are common in entry-level and domestic models.
Aluminium pumps offer a good balance between weight and durability and are found in a number of mid-range and higher-performance machines.
Brass pump heads are commonly found on premium and heavy-duty pressure washers where durability is a major consideration.
For example, the STIHL RE 170 PLUS uses a brass pump head and ceramic piston and produces a maximum pressure of 180 bar.
There isn't one pump material that's automatically right for everyone. Match the construction to how often and how heavily you'll use the machine.
5. Consider Hose Length and Overall Ease of Use
A pressure washer can have plenty of cleaning power and still be frustrating to use if the hose is too short or the machine is awkward to move.
Look at:
- High-pressure hose length
- Power cable length
- Hose reel
- Wheel size
- Machine weight
- Handle design
- Accessory storage
A longer hose can save you from constantly moving the pressure washer around the driveway or garden.
A hose reel is another useful feature, particularly if you use your pressure washer regularly. It helps keep the high-pressure hose organised, makes packing away easier and reduces tangling during storage. When comparing STIHL pressure washers, check the hose storage options and included accessories to find a model that suits your workspace and cleaning routine.
6. Understand Pressure Washer Nozzles and Spray Patterns
The nozzle determines how the water is delivered to the surface, so it's just as important as the machine itself.
A narrower spray concentrates more cleaning force into a smaller area, while a wider spray spreads the water over a larger surface.
For vehicles, painted surfaces and timber, start with a wider spray and keep the nozzle at a safe distance. If you're unsure, start gently and work your way up.
7. Choose the Right Accessories to Get More from Your Pressure Washer
The right accessory can make a bigger difference than simply buying a more powerful machine.
Surface cleaner:
Useful for patios, paths and other large flat surfaces. It helps create a more consistent clean and can make large areas much quicker to cover.
Foam cannon or detergent attachment:
Applies detergent evenly across a vehicle or surface before rinsing. This can help loosen dirt and grime before you use the pressure washer.
Rotary nozzle:
Produces a rotating concentrated spray and is useful for stubborn dirt on suitable hard surfaces.
Extension lance:
Provides additional reach when cleaning higher areas or difficult-to-access surfaces.
Wash brush:
A softer brush can be useful for vehicles, outdoor furniture and other surfaces where you don't want to rely entirely on high-pressure water.
Suction kit:
Some pressure washers can draw water from an alternative source, such as a tank or water container, where the machine is compatible with it.
Before buying accessories, check that they're compatible with your particular pressure washer.
8. Check Warranty, Spare Parts and Local Servicing Before You Buy
A pressure washer is a machine you'll hopefully keep for years, so don't overlook what happens after the sale.
Check whether the manufacturer provides:
- A clear manufacturer's warranty
- Genuine replacement parts
- Local servicing
- Technical support
- Accessories and replacement hoses
- An established dealer network
This is particularly important if you're buying a higher-performance machine or expect to use it regularly.
A cheaper pressure washer isn't necessarily cheaper in the long run if replacement parts are difficult to find or there's nowhere local to get it serviced.

5 Common Mistakes to Avoid When Buying an Electric Pressure Washer
1. Buying Based Only on PSI
A high PSI figure looks impressive, but it doesn't tell you everything about a pressure washer. Water flow, motor type, pump quality and nozzle selection all affect how the machine performs.
2. Ignoring Water Flow Rate
Two pressure washers can have similar PSI ratings but clean differently. Check the L/min figure as well as the pressure.
3. Buying More Power Than You Actually Need
If you're mainly washing the car and cleaning garden furniture, you may not need a heavy-duty pressure washer. A smaller machine can be easier to store, move and use.
4. Forgetting Essential Accessories
The right surface cleaner, vehicle kit, foam attachment or nozzle can make a bigger difference to the job than you might expect.
5. Ignoring Warranty and Servicing Support
Think beyond the initial purchase price. Access to genuine spare parts, servicing and manufacturer support can make ownership much easier over time.
Final Thoughts
The best electric pressure washer isn't necessarily the most powerful one. It's the one that matches the jobs you actually need to do.
Start by thinking about what you'll be cleaning most often. Then compare pressure, water flow, motor type, pump construction, hose length and available accessories.
For most homeowners, an electric pressure washer offers a convenient way to clean cars, outdoor furniture, patios, decks and other areas around the property without the fuel and engine maintenance associated with petrol models.
If you're buying a more powerful machine for regular or demanding work, it's worth looking beyond the headline PSI figure and considering the overall build quality, warranty, servicing and availability of genuine spare parts.
