Pressure Washer

Hi, and thank you for your help.

Has anyone made/created a pressure washer. Here is link: http://www.nextag.com/SIMONIZ-1300-PSI-Pressure-582276230/prices-html.

I am wondering if someone has made somthing small, like the one in the link. Or, this link: http://www.amazon.com/Ultra-Portable-Compact-1700-Pressure-Washer/dp/B000U5V018

Thanks for any and all help.
