2In1 Surface Cleaner 16.5Inch Undercarriage Washer Pressure Washer Max 4000PSI 1/4 Quick Connector with Universal Wheels and Wands for Car Ground Cleaning

Frequently Asked Questions

Will this surface cleaner work with my pressure washer?

Yes, this 2-in-1 surface cleaner is compatible with most pressure washers on the market. It's designed to work with pressure washers that have a maximum pressure of 4000 PSI and a maximum flow rate of 4 GPM. The 1/4" quick connector fits standard pressure washer hoses. If your washer is rated at or below 4000 PSI, you're good to go. Just make sure you check your pressure washer's specifications before purchasing.

Can I use this for both my driveway and car undercarriage?

Absolutely – that's what the 2-in-1 design is all about. The 16.5-inch surface cleaner works brilliantly on large flat surfaces like driveways, patios, decks, and sidewalks. But it's also specifically engineered for car undercarriage cleaning, which makes it perfect for removing stubborn road dirt, sand, mud, oil, and fuel contaminants. The 360-degree universal wheels give you the mobility you need for both jobs, and the dual high-pressure nozzles handle everything from light mud to tough grime without streaking.

What surfaces will this damage, and what surfaces is it safe for?

This cleaner is designed for most horizontal surfaces including concrete driveways, timber decks, patios, and undercarriage. The dual high-pressure nozzles and tough flexible bristles are engineered to clean effectively without striping or streaking surfaces. However, we'd recommend testing on a small inconspicuous area first if you're using it on sensitive surfaces like rendered walls or painted finishes, as 4000 PSI is quite powerful. The bristles help control water splash and protect surrounding areas during use.

How long will delivery take, and do you offer returns?

Yarra Supply offers Australia-wide free shipping on this product, so you won't pay extra for delivery across the country. Most orders arrive within 5-10 business days depending on your location. If you're not entirely happy with your 2-in-1 surface cleaner, we offer a 30-day returns policy, so you can shop with confidence. Just contact our team if you need to arrange a return.

Is this heavy to move around, and how does it stay in place during use?

The surface cleaner weighs enough to stay stable under high pressure – this is actually a design feature. The heavy-duty stainless steel construction means the dome housing won't rise up when you're operating it at 4000 PSI, making it easy to control and effort-saving. The four universal castors with wheels provide excellent mobility, so despite its solid build, you can roll it around your driveway or underneath your car without struggling. This design means less effort and time spent cleaning.

What's included in the box, and will I need to buy anything else?

Your 2-in-1 surface cleaner comes complete with two extension wands and one angled wand, all fitted with 1/4" quick connectors. You'll have everything you need to get started – just connect it to your existing pressure washer and you're ready to clean. No additional attachments are required, though you may want to grab a pressure washer if you don't already own one. The package includes everything specified in the product bundle.

How much area can this cover in one pass?

The 16.5-inch cleaning width means you'll cover a decent-sized area with each pass. For a standard driveway or patio, this translates to faster cleaning times compared to smaller nozzle attachments. The dual spinning nozzles working across that 16.5-inch width deliver commercial-level cleaning results, so you're not spending all day on a single project. Combined with the mobility from the four wheels, this is designed to be time-saving and effort-saving for Australian homeowners tackling regular outdoor cleaning.
