M MINGLE Pressure Washer Undercarriage Cleaner, Under Car Wash, 4000 PSI (13 Inch)

It’s too good for 4 stars, not quite good enough for 5. Why? Well now, I’m so glad you asked! Obviously I’m using it to clean the underside of vehicles, specifically old Toyota Land Cruisers, meaning they have 40+ years of gunk underneath. Powering it with a gas 4000psi pressure washer. It’s good!! Four jets with overlapping spray pattern more than 12” (30cm) wide and producing enough force to knock loose rust and junk even though the underside of the 4WD truck is a lot higher up than your average car or 2WD vehicle. It did not peel off the coagulated grease that’s encapsulating the transmission, but when I tried to do so with the pressure washer nozzle directly it also didn’t come off, so that “failure” wasn’t really a failure of this roller thingy, just super-tough gunk. Blah blah blah. The thing that wasn’t great is that tor some reason it rolls perfectly when not spraying, but when you begin blasting it doesn’t want to roll sideways. Forward & back, no problem. Side to side, nope. It’s like the castors lock in that direction, somehow. You can force it to go sideways with some effort but it doesn’t want to roll smoothly and freely like it does without the water flowing. Definitely not a big deal for me, but someone out there is going to have a screaming fit and demand to speak to the manager because it isn’t rolling freely sideways. If that person is you….wow. The rest of us don’t like you. Just saying. For everyone else this is a good undercarriage washer thingamajig!

This is the perfect way to clean the undercarriage of a vehicle! Washed my car at the car wash the other day and realized that since I didn’t do the automatic wash, the underneath of my car still had salt and grime. Came home and bought this. Works great!!

This undercarriage cleaner is a total game changer for me 🙌. I used to dread trying to clean the underside of my truck after off-roading or rainy days because it meant getting dirty and crawling around like a mechanic 😂. With this attachment, I just hooked it up to my pressure washer and rolled it underneath — boom, all the mud and grime gone in minutes! 💨💧It’s solidly built, rolls smoothly, and the spray pattern covers everything evenly. The pressure is strong enough to get rid of caked-on dirt but not so aggressive that I worry about damaging anything underneath. Super easy to connect and use! 🔧✨If you’re tired of bending, crawling, or skipping the underbody altogether, this is 100% worth it 👏🔥.

This attachment did a great job cleaning a ton of crud off the bottom of my truck. My only gripe, as others have mentioned, is the casters. They work well if you have things at exactly the right angle; otherwise you're battling to position it.I'd probably recommend a version with the fixed wheels on the ends. That said, having already spent the money I'll happily continue using this tool with no plans to replace it with something different.

Works great. Muddy water and dirt just pours off the bottom of car. We have a 3300 psi pressure washer though and when we pulled the trigger with it not under the car it sprayed all the way to our 11' tall ceiling. This is that under body wash that every northern car needs that carwashes charge extra for. The one thing before we couldn't do at home. Good purchase glad I made it.

This is hugely useful washing salt off the bottoms of my vehicles in Michigan winters. Make sure your pressure washer has enough flow to run 4 nozzles, at least 2GPM.

For $25 this thing is great. I can blast out the bottom of my truck in minutes using my cheap Sun Joe 1.3 gpm power washer. The casters work great. No issues with the sprayers. Its a nicely machined hunk of metal for a very low price. I found I didn't need the extension piece. I just used the wand I already had for the rest of my spray tips. Great value especially if using it is going to save me from rust issues from driving on salted roads.

This was tested with a gas 3000psi, 2.4 GPM Pressure washer and it is great! The build quality is as good as it gets from china. I have a gravel driveway and the wheels still work very well.
