AURORA CAR Dual-Function Undercarriage Pressure Washer Attachment 16 Inch | Undercarriage Cleaner, Under Car Wash Water Broom with 3 Extension Wands, Power Washer Surface Cleaner, 4000 PSI

Works really well. Should have bought along time ago.

Using this to clean composite decks, comes ready to go, just connect and you're ready to clean. Also tried this after a mudding outing and this worked well on the undercarriage.

This attachment is a game changer. I used to dread trying to clean underneath my car, but this completely eliminates the need to crawl around on the ground. You just slide it under and let the pressure washer do the work. It’s super satisfying to see all the dirt and grime get blasted away. The build quality feels solid, and the wheels roll smoothly, making it easy to maneuver under the vehicle. The included extension wands are also a big plus, they give you plenty of reach without having to bend or strain. Setup was quick with the standard quick-connect fitting, and it worked perfectly with my pressure washer right out of the box.

I wasn’t sure what to expect when I ordered this undercarriage washer attachment, but after using it a few times I actually get why folks rave about it. It’s basically a 2-in-1 pressure washer tool that doubles as a surface cleaner and a foam-cannon sprayer, so you’re not just blasting the dirt off the bottom of your vehicle but also can shift into cleaning driveways and decks with ease. The quick-connect wands and the way it rolls under your car save you from the miserable crawling-around routine that most of us dread every time winter salt or mud gets packed in under the frame. When you’ve got a decent pressure washer (I use a 3300PSI Honda / Ryobi), the spray pattern clears away dirt, salt, and grime better than a garden hose ever could. It’s not built like a tank — there’s some flex in the extension tubes and if you’re really hard on tools the plastic fittings can feel a bit light — but I haven't had any issues with it yet. What stands out is how this thing makes a chore feel almost worth doing. Instead of dragging out awkward brushes or multiple tools, you hook this up, roll it under your ride, and wipe away weeks of road crud without lying on the cold ground. You won’t get perfect results every time, but for everyday maintenance it’s a big step up from conventional car washes or guessing at angles with a wand. Worth the purchase? Yep.

I’m pretty sure I’m not unique here, but the underside of my truck gets absolutely nasty—especially behind the bumper where sand, dirt, and winter road grime seem to pack in and never come out. I live in the Chicago area, where the roads get salted heavily, and while that buildup might not cause immediate problems, I really don’t like leaving salt and gunk sitting underneath the vehicle. That’s exactly why I picked up this undercarriage pressure washer attachment—and honestly, it works great. The first thing I noticed is the solid stainless steel construction. It feels well made, not flimsy, and the two-wheel design rolls smoothly thanks to what seem like decent bearings and rubber wheels. That makes it easy to slide back and forth under the vehicle without fighting it. One feature I really liked is the pivoting connection where the pressure washer hose attaches. You can rotate it to get the correct angle depending on what part of the vehicle you’re trying to reach, which makes setup and use much easier than I expected. It also comes with three extension wands, which is a big plus. With those connected, you can reach well toward the middle of the vehicle without crawling underneath. You just lean over, roll it back and forth, and let the pressure washer do the work. It had plenty of pressure to blast away packed-in grime, dirt, and salt. For me, the biggest benefit is getting that road salt off after winter. Anything that helps reduce rust and corrosion while being quick and easy to use is a win. This lets me knock out a fast undercarriage wash without making a huge mess or turning it into a full project. Overall, it does exactly what I hoped it would: makes undercarriage cleaning easy, effective, and much less annoying. I’ll definitely be using this regularly.

This undercarriage pressure washer attachment honestly needs no pictures or videos to prove how well it works, you just have to use it. I was skeptical at first about how effective it would be at cleaning under cars and trucks, and I also wasn’t sure how useful the water broom feature would be. Turns out, both work perfectly. I ran it under multiple cars and trucks, and it did an outstanding job cleaning the undercarriages blasting away dirt, grime, and buildup with ease. After that, I backed the vehicles out of the driveway, switched it over to water broom mode, and cleaned up all the dirt and debris that had washed off from underneath. That mode worked just as well, leaving the driveway clean and finished. The dual-function design is what really makes this shine. You’re not just buying a one trick tool, this attachment handles two jobs extremely well without feeling gimmicky or underpowered. It’s solid, effective, and does exactly what it claims. Simply put, if I could give this six stars, I would. It’s well worth the money and easily one of the most useful pressure washer attachments I’ve ordered. Highly recommended.

I used this thing all winter to get the salt off our cars, works great. This thing is a true workhorse of an attachment for our pressure washer. Its amazing what gets stuck under there.
