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.

Abstract: A floor cleaning attachment is configured to attach to a pressure washer lance to receive a flow of fluid. The floor cleaning attachment includes a housing that defines a suction space and includes an attachment point configured to attach to the pressure washer lance to receive the flow of fluid. A rotatable brush is coupled to the housing, a vacuum producing member is coupled to the housing, and a valve is coupled to the housing and movable between a first position in which the flow of fluid is directed onto a floor, a second position in which the flow of fluid is directed to the vacuum producing member to produce a partial vacuum, and a third position in which the flow of fluid is directed to the rotatable brush to rotate the brush.

Abstract: A nozzle for use with a pressure washer, and the nozzle includes a body portion that defines a longitudinal axis and a head portion coupled to the body portion and in fluid communication with the body portion. The head portion includes a face substantially perpendicular to a longitudinal axis of the body portion. An elongated first slot is disposed upon the face of the head portion, and an elongated second slot is disposed upon the face of the head portion and in a nonparallel orientation with respect to the first slot. A fluid outlet aperture extends through the face and is at least partially located within at least one of the first and second slots to allow a fluid flow from within the body portion to exit the nozzle from the head portion.

Abstract: A pressure washer includes a frame, a power unit supported by the frame, a pump for raising the pressure of a fluid from a fluid source and being driven by the power unit, and a detergent tank positioned upstream of the pump and configured to hold a cleaning solution. The detergent tank is closed from the atmosphere and configured to be pressurized to at least a pressure of the fluid source. The detergent tank has a tank inlet configured to receive the fluid from the fluid source and a tank outlet configured to provide a mixture of the fluid and the cleaning solution to the pump.
