A couple weeks ago someone on here brought up undercarriage washing and someone else posted a link to an undercarriage attachment for pressure washers on eBay. For $49 I figured what the heck and ordered one.
It arrived just 3 days after ordering. It was well packed and is a stout, well constructed attachment.
Easily attached to my pressure washer by just unscrewing the nozzle attachment from the wand/trigger assembly, then screwing the undercarriage extension piece on. The undercarriage washer assembly itself is two casters, a metal bar and four nozzles with quick connect attachment that the extension piece goes onto.
I fired it up and water sprayed from all four nozzles (for a little while).
One problem I encountered were the outer nozzles clogging. Some pieces of debris (looked like metal shavings) became lodged in the outer two nozzles.
I grabbed two wrenches, removed the nozzles and cleaned them out real quick.
Notice the left nozzle not sending out any water. It had clogged completely and the right nozzle is partly clogged. After cleaning they were fine.
Here it is after cleaning the outer two nozzles out. They now spray great!
I find the undercarriage attachment very useful. I'm able to reach all the way to the middle of the vehicle without having to get onto the ground and get wet. A good deal of pressure is utilized and does a good job of cleaning. You need to be careful around the outer edges of the vehicle because if you pull the washer out too far without angling the water jet back into the underside of the vehicle, you'll get sprayed.
