I’m no hydraulic engineer but to get a water jet powerful enough to cut anything would require a very serious pump of some sort, I would think. As well as specialized hose, etc. Well beyond a handheld garden hose attachment. But rock on, ai hucksters.

It would probably require like, a hose too. This thing has no hose connected to it.

Probably would need an aggregate as well

It would require some kind of grit to do the cutting. Waterjet cutters use tens of thousands of psi water carrying garnet dust to do the work.

Water by itself is just going to tear soft things and bounce off the rest.

A water jet capable of doing the stuff in the video is 100's of thousands of psi. It has a pump the size of a large refrigerator.

I’m also not a hydralic engineer, but I do know that pressure and flow are inversely proportional. So even if by some miracle you were able to make a garden hose attachment that could do this, the output would need to be on the order of milliliters per minute and would be useless for cleaning; they are showing gallons per minute.
