I purchased this to clean mud/dirt/salt from underneath my vehicles and it does a great job of doing that. You do need to pay attention to the minimum psi/gpm specs that it requires. I'm using a relatively light duty (under the minimum specs) electric pressure washer and I can tell that it's not performing as good as if I was using something more powerful.

My several cars were packed with dried on mud from months of travelling on our gravel road. This undercarriage pressure washer attachment made short work of cleaning all along the underside of the rocker panels. Great satisfaction in seeing the mud dropping down and reaching underneath after cleaning to feel nice clean underside of the cars. This product is sturdy and easy to use. Wonderful.

I have now used this extension wand a couple of times, and I love it! I was able to clean to the top of my 2 story house without any problems. It is super sturdy, little to no deflection, and easy to handle with any size nozzle. I previously had a longer extension wand(not a westinghouse) that bent so much when using I had to return it. I have also used my new extension wand with a foam canon on the end and this makes for a great cleaning combo. I would highly recommend this product.

Bought a couple of days ago so I have only used it once. It works great for getting the mud off of the underside of my van. I have used a similar product before but it only had 3 jets. the extra jet puts a lot more water under there with great results.

I did not expect this to be made entirely (it appears) of stainless steel and brass. For the affordable price, the quality amazes me. I use it for washing the underside of my Landcruiser after overlanding trips where it's common for the underside to get caked with mud, and in the winter (horrors) road salt. For that it works great. I honestly can't see how this thing could be improved. I only wish I had bought it earlier.

Great product, works really good, keeps me off the ladder and saves me a lot of time. The full length of all 3 tubes has a really nice reach. Very comfortable to use with two tubes for lower projects, you don't get as much spray or splash back on you. I would recommend this product.

Bought product mainly to clean my vehicle undercarriage. I live in Tennessee and during the winter months the roads are covered with salt and other corrosive chemicals that will cause rusting of the underside of your vehicle. Product performs as advertised and is well worth the price. I am very satisfied and just waiting for the arrival of the bonus spray nozzles that were promised for registering my water broom/undercarriage washer.

Got this as a Christmas gift last year and it's made cleaning the garage and underside of my truck much less frustrating. Broom helps me move all the wet debris that I missed until after it got wet out the garage and from under the truck. Also helps push all that pooled water from washing everything else around. Getting the salt off the truck without having to wait for car washes or mud when I need to fix something has been great too.

I just used my Undercarriage cleaner yesterday for the first time. It works very well. I had a lot of debris in my driveway from all the salt and grime it washed off from another Winter in Michigan. It should reduce corrosion caused from salt deposits.

I believe this product will work well for what it is intended for such as rinsing off the undercarriage of a car after driving on salt roads, or using a water broom. I wanted to use it for the underside of my zero turn mower deck but with multiple nozzles and a broad pattern installed, there wasn't enough power to knock down the thick grass accumulation. But I think it is a good product for what it is designed for.
