Abstract
A portable pressure washer system includes a frame having at least one strap configured such that the frame is supported by a user by way of the at least one strap. A torque generating device is supported by the frame and has an output shaft. A pump is selectively coupled to the output shaft to receive a torque generated by the torque generating device. The pump includes an inlet for connecting to a remote fluid source and an outlet for connecting to a high pressure fluid delivery mechanism. The pump receives a fluid from the remote fluid source by way of the inlet, is driven by the torque generating device to raise a pressure of the fluid to a high pressure fluid, and delivers the high pressure fluid to the high pressure fluid delivery mechanism by way of the outlet.
