Pressure washers are apparently made out of many complex parts and assembly is not all automated. So, most of the pressure washers are made in China. We have only found one company that makes pressure washers outside of China.

Ryobi
Ryobi is a huge company that manufactures tools all over the world. They happen to be the only company that we found that makes pressure washers outside of China. Their pressure washers seem to all be manufactured in Vietnam.
