Getting under a car to hose off road salt and mud means lying on cold, wet pavement, and most people just skip it. This undercarriage pressure washer attachment clears the underside from a standing position instead, running at up to 4000PSI for 5X higher efficiency than crawling around with a bare wand. Switch the pivot connector and the same tool becomes a pressure washer surface cleaner for the driveway, so avoiding the crawl doesn't mean buying a second attachment.

As a car undercarriage cleaner or an undercarriage washer it reaches the underside in a few passes, and the 1/4-inch quick connector fits any 1/4-inch pressure washer, so it works with the machine you already own.
