Liebherr car wash. Here’s what happens when you dump 22,000 litres of water on a car from 6 metres high.

A common question about pressure washing is: If I wash my car with a heavy-duty pressure washer will it damage it?

The answer is that you can avoid damage by using the correct nozzle at the correct distance. The more heavy-duty the pressure washer the further you should keep the stream from the car.

When I watched this video of a Liebherr R9400 Shovel dropping 22 tonnes (22,000 L) of water on a car it made me think about pressure washing a car with super crazy heavy-duty pressure.

Anyways, that’s why I’m sharing it with you here. It’s pretty cool to watch. There’s some pictures after the video.

The water, from that height, has the equivalent momentum (mass x velocity) of that same car going 50 mph (80.5 km/h). And if you look at the damage to the car… It’s about the same as you would expect from a car accident at that speed, yeah?
