I really like this 16 inch underwater carriage broom it works well and has lots of pressure, Westinghouse has great products at a great price will buy from them again.

Great Product

walmart.com

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.

Incredible quality for the price

Works great to quickly “sweep” off the driveway and pool deck without leaving a lot of water behind and without applying too much pressure to the concrete surface. I also used it to clean under my trucks. The included extension are great and useful for other projects as well

Works great and the included extensions are added

This is perfect for the off-roaders!  Easy gets where you need to hit the mud and dirt.  Tell your friends to get there own because I'm tired loaning mine out. Best part is once the mud hits the ground just flip it over and start power sweeping.

Solid, better than expected!  2 tools in 1.

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.

Great tool for cleaning your undercarriage

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.

Sturdy and Works Great

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.

Does what it should. Been great

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.

Works Well

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.

Great Design

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.

Good product for what it is designed for.

The description of this product say it is 3400 rated and 3200 rated. My Westinghouse 3400 pressure washer blew out the hose on its first use.

NOT 34000 PSI rated
