  • Patent number: 8118241
    Abstract: A surface cleaner system includes a base assembly having a housing movable along a surface, a pump supported by the housing and operable to pressurize a fluid, and a prime mover supported by the housing. The prime mover is coupled to the pump to drive the pump. The surface cleaner system also includes a spray assembly coupled to the housing. The spray assembly is operable to discharge fluid from the pump toward the surface. The surface cleaner system further includes a spray gun in fluid communication with the pump to receive pressurized fluid from the pump. The spray gun includes an outlet portion that is connectable to the base assembly to direct the pressurized fluid from the pump into the spray assembly. When the outlet portion is disconnected from the base assembly, the spray gun discharges the pressurized fluid from the pump toward the surface without directing the pressurized fluid into the spray assembly.

  • Publication number: 20090065607
    Abstract: A spray apparatus for a pressure washer includes an adaptor configured to receive a flow of pressurized fluid through a conduit fluidly connected with a pressure washer. A multi-position valve is movably connected with the adaptor and positionable in a plurality of discrete positions. The valve position is modified with an operator engaged with the valve. A first output and a second output are defined within the adaptor, wherein the valve is rotatable to selectively allow the pressurized fluid to flow through one of the first or the second output.

  • Publication number: 20080272150
    Abstract: A spray system is disclosed having a housing and a blower motor and a pump assembly within the housing. A first output line is in fluid communication with the blower motor to provide a low-pressure stream of air. A second output line is in fluid communication with the pump assembly to provide a low-pressure fluid. An egress is attached to the housing, and the low-pressure fluid joins with the low-pressure stream of air and exits the housing through the egress.
