Debarking logs with a pressure washer - GIF

What's going on here? Unusually powerful pressure washer? Only works on a specific species of wood? Logs have been prepped somehow?



Regardless, this reminds me that I remain in search of a long German word that means, roughly translated:

"When you are happy to see a new way to do something, but also saddened by the realization that you have spent many years doing it the wrong way."
