Impressive under carriage washer

Using it to wash under carriage of truck and car because New England has road salt during the winter. Unit is durable and well built. I like the heaviness of the product ensuring its durability. Seems like it will last for years

Great for cleaning under the car

I use this for cleaning under our cars; it's a little awkward to use at times, and you can douse yourself if your extension is not long enough; overall it's well built, it's very effective, and definitely a great tool for the money.

Perfect for After Winter Cleanup!

I had not seen anything like this before and when I found it, I knew I needed one. Living in an area where salt and chemicals are used often and repeatedly, it is vital that I keep the underside of my cars and truck flushed from the rust inviting and abrasive quality of these ice melting products. It is very well made, lightweight, and easy to roll around to ensure complete coverage.

Great idea!

We have side by sides and go wheeling almost every weekend. Getting the under side clean after playing in the mud was almost impossible. This worked perfectly!! Wish I would have found it years ago. Good quality fittings and well made. Highly recommend!!

If you’re thinking don’t think just buy it!

One of the most amazing products to use as a professional auto detailer, 10 years of getting on my hands and knees to spray underneath every car. This undercarriage washer accessory with an extension wand is just the best thing you could ever have!
