RIDGE WASHER Pressure Washer Undercarriage Cleaner, 16 Inch Undercarriage Washer with Foam Cannon, Under Car Cleaner with Straight Extension Wand, 4000 PSI

So simple and a great solution to get the winter road treatment off of your vehicle.

The under car pressure washer roller works really well. I only have a 2300psi washer so I probably need over 3000psi as the roller takes more pressure than a single tip pressure washer. Either way, it was easy to put together and easy to use and worked with either of my pressure washers. It’s compatible with any normal pressure washer attachment. I wish it had more power but that’s just due to my pressure washer being electric and not gas. Great bang for the buck to get the mud out from under my truck from wheeling and camping. Definitely need more power.

Purchased this back in September of 2025. This is the second time I have used it since. First time I had no issued and no keakes. Today I used it again and it started to leak. Adley from both ends of the foam cannon and quick connects. Made sure quick connects where locked in and nothing was lose on the foam canon. Yet here you go

Foam was little bit too thin, next time trying more foaming agent. Pressure nozzles work fine and wheels are super smooth

This pressure washer undercarriage cleaner is exactly what I was looking for. I live in South Eastern Pennsylvania where some winters can be very cold and there are times when the roads get covered with snow or ice. The result is that salt can accumulate along the undercarriage. Since my new car came with a ceramic coating, it is recommended to not run them through a car wash. I purchased a foam cannon to clean the body of the car but still had no solution until I came across the Ridge Washer for the under carriage. In spite of some reviews stating it leaked at all the connections, I figured I would give it a try! As long as you follow the manufacturer instructions, I feel this is not the case! The cleaner comes with to different sets of sprayer heads. The one set is i believe stainless with larger holes to allow the foam to flow freely and to reduce the pressure on the unit to avoid leaks. The second set are made of what i believe is brass and has much smaller holes. The smaller holes create more pressure for water to rinse the foam and loose debris. I have only used it one time so far and the cleaner worked as it should. It produced plenty of foam and I was impressed with the pressure of the rinse water as well! I really like this cleaner and would recommend it to those that are sitting on the fence due to some negative reviews!

First, I read the reviews about how the foam cannon was junk and they were correct. After one use the foam cannon started leaking! Poor quality imo. Second, I said if the foam cannon is junk, I'll order an injector system for it bc I have another undercarriage washer with the stainless fitting for water. Im glad I ordered the injector system bc I didn't have any down time waiting on responses or replacement. So lastly, just order this and a pressure washer injection system and your go to go!

I bought this to pressure wash the undercarriage of the car from road salt. It was great that the angled foam cannon and extending wand was included in the box. Most undercarriage brooms doesn't have large enough orfices to be able to dispense foam detergent to get the job done. With this item I would have the option of using the foam cannon or not. I do have another less expensive undercarriage broom with regular orfices that I use to rinse as it would make the job easier. The product is sturdy and I would highly recommend it.

Every now and again you find a tool and figure I'll take a shot. I bought this in Winter know full well I'd be long past the return window if there is an issue. Well I set it up yesterday 4/11/26 and went to on my my wifes SUV. At first I was thinking ummm ok its blowing a lot of soap and I do mean a LOT OF SOAP but where i the winter dirt. Then literally came a swarm of black/brown and gross soap with the dirt. So I hit it again and much more came out. So I let it sit with the soap for maybe 7-10 minutes and went to straight water. The dirt I can assure you is ALL gone and the water I sprayed I continued until it ran clear. The overall Power is superb The water pressure is depended upon 2 things your power washer and your supply. In my care the pressure was amazing it is very versatile in moving it around to get every inch of the undercarriage The value for the money lets just say using this item even 4 times annually as it only took a total of 10-15 minutes will save you over $200.00 at the car wash. If you enjoy your car and have pried in it - DO NOT PASS THIS BY

Great product, Fast Shipping

bon qualité

Great for undercarriage use no issues

Looks to be great product haven’t used it yet summer time. Looks to be solid.

Unfortunately, I didn't try to use the foam cannon until 6 days after the return period expired. One of the reasons I purchased this was for the foam cannon feature which I cannot use. If you purchase, make sure you test everything out right away.
