A pressure washer straight out of the box is capable of impressive cleaning. But with the right accessories, you can dramatically expand what it can do, how efficiently it works, and how professional your results look. From time-saving surface cleaners to precision detailing tools, the accessory market offers solutions for almost every cleaning challenge.
The question isn't whether accessories are worth buying—it's which ones actually deliver value for your specific needs. Some are genuinely transformative, while others are gimmicks you'll use once and forget about. This guide will help you separate the essential from the unnecessary.
Surface Cleaners: The Game Changer
If you only buy one accessory, make it a surface cleaner. This circular attachment contains spinning spray bars that clean large flat areas dramatically faster than a standard spray wand—and without the striping that manual spraying often produces.
How They Work
Water enters the surface cleaner and exits through two or more nozzles mounted on a rotating bar. As water sprays out, the bar spins, creating an even cleaning pattern across the circular footprint. A housing contains the spray and allows you to guide the cleaner across the surface smoothly.
The Benefits
- Speed: Clean driveways and patios 3-4 times faster than with a spray wand
- Consistency: No more visible stripe patterns from overlapping passes
- Reduced splash: The housing contains most of the spray, keeping you drier and protecting nearby areas
- Less fatigue: Push instead of aim—much easier on your arms and back
Surface cleaners come in various sizes (typically 28-40cm diameter for domestic use). Match the size to your pressure washer's capability—too large and it won't clean effectively; too small and you lose the speed advantage. Check the manufacturer's PSI and LPM requirements.
Foam Cannons and Snow Foam Lances
Car enthusiasts swear by foam cannons, and for good reason. These accessories mix detergent with air and water to create thick, clinging foam that dwells on surfaces and loosens dirt before you touch the paintwork.
Why Foam Matters
Traditional pressure washer detergent application (through the soap nozzle) delivers a thin layer of cleaning solution that quickly runs off. A foam cannon produces dense foam that clings to vertical surfaces for minutes, giving the cleaning agents time to break down dirt, grime, and road film. This pre-wash step dramatically reduces the risk of scratching during contact washing.
What to Look For
- Adjustable foam thickness: Control the air/water ratio for different applications
- Spray pattern adjustment: Wide pattern for panel coverage, narrow for wheels
- Quality construction: Brass fittings outlast plastic
- Compatible connectors: Ensure it fits your pressure washer's quick-connect system
Key Takeaway
A quality foam cannon combined with a dedicated snow foam detergent is one of the best investments for safe car washing. The foam does most of the work, reducing the scrubbing that causes swirl marks.
Extension Wands
Standard spray wands are typically 40-50cm long. Extension wands add 60-120cm or more, letting you reach second-storey gutters, high walls, or the top of caravans without a ladder.
Benefits
- Reach high areas safely from the ground
- Clean under vehicles and equipment without bending
- Keep you further from the splash zone
- Reduce pressure washer recoil at the operator end
Considerations
Longer wands reduce control precision and can be heavy when extended, especially with water flowing. Telescopic options offer flexibility but add complexity. For most home use, a fixed extension of 60-90cm provides a good balance of reach and control.
Gutter Cleaning Attachments
These curved wand attachments are designed specifically for cleaning gutters from ground level. The curved end directs the spray into the gutter while you stand safely below.
What They Include
- Extension wand (often telescopic)
- Curved attachment that hooks into the gutter
- Sometimes a support harness for the extension
Effectiveness
These work reasonably well for flushing debris from gutters, but they don't replace manual clearing for heavily blocked downpipes or compacted leaves. Think of them as maintenance tools for keeping mostly-clear gutters flowing, not rescue tools for years of neglect.
Even with extension attachments, cleaning gutters with a pressure washer creates significant splash back. Wear full eye protection and expect to get wet. Never use these attachments from a ladder—the recoil and lack of control makes ladder work extremely dangerous.
Turbo/Rotary Nozzles
A turbo nozzle (also called a rotary nozzle or dirt blaster) combines the penetrating power of a zero-degree stream with a rotating motion, creating a circular spray pattern that cleans aggressively.
When to Use
- Heavy grease and oil on concrete
- Removing old paint or coatings
- Cleaning heavily soiled agricultural equipment
- Breaking up stubborn moss or lichen
When to Avoid
- Timber surfaces (will damage)
- Painted surfaces (will strip)
- Any surface prone to damage from concentrated spray
- Car washing (absolutely not)
Think of turbo nozzles as aggressive tools for tough jobs. They're not for general cleaning and require extra caution during use.
Replacement and Specialty Nozzles
Beyond the standard colour-coded set that came with your machine, you can buy individual nozzles for specific purposes or to replace worn ones.
Types Worth Knowing
- Variable/adjustable nozzles: Dial between patterns without changing nozzles
- High-efficiency nozzles: Designed to maximize cleaning power at your machine's specific PSI/LPM
- Underbody/angled nozzles: For cleaning under vehicles
- Chemical injection nozzles: Apply concentrated chemicals at low pressure
Nozzles wear over time, gradually enlarging the orifice and reducing pressure. If cleaning performance has declined despite good maintenance, worn nozzles might be the culprit. Replacement nozzles are inexpensive and easy to install.
Hose Extensions
Standard high-pressure hoses are typically 6-8 metres. If you have a large property or need to reach far from your water source, extension hoses can add another 6-15 metres of reach.
Considerations
- Pressure loss: Longer hose runs reduce pressure at the nozzle. For very long runs, you may notice decreased performance
- Quality matters: Use genuine manufacturer extensions or quality aftermarket hoses rated for your machine's pressure
- Storage: More hose means more storage space needed and more potential for kinks
Water Brooms
A water broom is essentially a wide, flat head with multiple nozzles spread across its width. It's designed for quickly cleaning large flat areas like car parks, warehouse floors, and sports courts.
For residential use, a surface cleaner usually makes more sense—water brooms are really designed for commercial scale operations where their wider cleaning path (often 60-90cm) justifies their awkwardness on smaller areas.
Brush Attachments
Rotating or fixed brush attachments combine water spray with physical scrubbing. They're useful for:
- Solar panel cleaning (gentle brushes)
- Vehicle washing (car wash brushes)
- Deck and fence scrubbing
- Heavy equipment with textured surfaces
Quality varies enormously. Cheap brushes shed bristles and don't rotate smoothly; quality units use durable materials and smooth bearings. For car washing, be cautious—even "car wash" brushes can trap grit and scratch paint if not used properly.
What to Skip
Not every accessory is worth buying. Consider skipping:
- Multi-function tools: Devices that try to do everything often do nothing well
- Extremely cheap sets: Bargain accessory kits often contain items you'll never use and quality issues with the items you would
- Sandblasting kits: Unless you have specific restoration projects, these require technique and safety equipment most homeowners lack
Key Takeaway
Buy accessories as you need them, not in anticipation of projects you might tackle someday. A surface cleaner is the one near-universal recommendation; beyond that, let your actual cleaning tasks guide your purchases.
