• the spray mop has a structure suitable for use as either a wet mop or a dry mop.
• the spray mop When used as a wet mop, the spray mop is able to project a fluid, such as a cleaning solution, in front of the mop and onto a surface for cleaning. The spray mop can then be guided over the surface by the user to clean the surface.
• the spray mop 100 can include a handle 102, a trigger 104, an external shaft 106, a grip 108, a spray housing 110, a bottle 112, a multidirectional joint 114, and a cleaning end 116.

• the bottle 112 is filled with a fluid for cleaning a surface, such as a floor.
• the bottle 112 is reusable and is removeably mounted to the spray housing 110 so that it can be filled with a desired fluid. As described further below, the bottle 112 is connected to a pump mechanism to draw fluid out of the bottle 112.
• the multidirectional joint 114 provides freedom of movement in multiple directions between the spray housing 1 10 and the cleaning end 1 16 such that a user can easily direct the cleaning end 116 along a desired path.
• the cleaning end 116 can have a plurality of attachment structures to connect a cleaning pad 1 18 to the cleaning end 1 16.
• the cleaning pad 118 can be any suitable type for any suitable surface to be cleaned.
• the spray housing 110 includes a nozzle 120 on its front surface.
• the nozzle 120 is generally directed forward and downward so that fluid exiting the nozzle 120 is sprayed onto a surface in front of the cleaning end 116 of the spray mop 100.
• the spray mop 100 can utilize a pump mechanism in the form of a mechanical pump to draw fluid from the bottle 112 to the nozzle 120 for spraying the fluid onto a surface.
• the components for operation of the mechanical pump can include the trigger 104, an internal shaft 122, a spring coupler 124, a reload spring 126, a sleeve 128, a piston 130, a piston housing 132, a fluid connector 134, a bottle base 194, two unidirectional valves (inlet 136 and outlet 138), a nozzle connector 140, and a nozzle 120.
• the trigger 104 can be attached to the handle 102.
• the trigger 104 can be pivotably mounted to the handle 102 with a proximal end 142 on one side of a pivot joint 144 and a distal end 146 on the other side of the pivot joint 144.
• the trigger 104 and handle 102 can be arranged such that a user's palm can rest on the top 148 of the handle 102 and one or more of the user's fingers can contact the trigger 104 near its proximal end 142.
• the user can clench the trigger 104 to pivot the proximal end 142 in a direction 150 toward the top 148 of the handle 102, and accordingly, the distal end 146 then pivots in the opposite direction 152.
• the distal end 146 is in contact with the internal shaft 122, which is disposed within the external shaft 106. As the distal end 146 pivots during actuation of the trigger 104, it depresses the internal shaft 122 to move it downward in direction 152.
• the trigger 104 can be any suitable shape and size and can be attached to the spray mop 100 in any suitable manner.
• the internal shaft 122 can be in contact with a spring coupler 124, which is surrounded by a reload spring 126.

• the piston housing 132 can be disposed at least partially within an open cylinder 158.
• the internal shaft 122 is moved downward to push the spring coupler 124 downward and compress the reload spring 126.
• the reload spring 126 can compress, for example, by contacting an interior ledge 160 of the sleeve 128 as the spring coupler 124 moves downward.
• the reload spring 126 can be compressed between the upper end 162 of the spring coupler 124 and the ledge 160.
• the spring coupler 124 moves downward, it also moves the piston 130 downward.
• the reload spring 126 Upon release of the trigger 104, the reload spring 126 exerts a force upward against the spring coupler 124 to move the spring coupler 124 and pull the piston 130 back to their initial positions, which likewise results in the internal shaft 122 and the trigger 104 moving back to their initial positions.
• the reload spring 126 may be disposed in a position with respect to the piston 130 such that the reload spring is not exposed to fluids that enter into the piston housing. This arrangement can reduce wear on the reload spring, which could be damaged through extended exposure to certain fluids that may be used with the spray mop 100.
• the piston 130 is situated in the piston housing 132.
• the piston housing 132 can have an interior surface 131 surrounding the piston 130.

• a fluid chamber 170 is formed between the piston 130 and the lower surface 168 of the piston housing 132.
• the piston 130 moves downward, it decreases the volume of the chamber 170 and pushes fluid out of the chamber 170 through the fluid outlet 166.
• the piston 130 moves upward, the volume of the chamber 170 increases and a pressure differential is created so that fluid is drawn into the chamber 170 from the fluid inlet 164.
• the reload spring 126 can be disposed outside of the fluid chamber 170 to prevent contact between the reload spring 126 and the fluid.
• both the fluid inlet 164 and the fluid outlet 166 can be connected to a suitably oriented unidirectional valve.
• a unidirectional inlet valve 136 can be attached to the fluid inlet 164 such that fluid is able to flow into the chamber 170 of the piston housing 132 through the fluid inlet 164, but fluid is not able to flow out of the fluid inlet 164 through unidirectional inlet valve 136.
• a unidirectional inlet valve 136 can be attached to the fluid inlet 164 such that fluid is able to flow into the chamber 170 of the piston housing 132 through the fluid inlet 164, but fluid is not able to flow out of the fluid inlet 164 through unidirectional inlet valve 136.
• a unidirectional inlet valve 136 can be attached to the fluid inlet 164 such that fluid is able to flow into the chamber 170 of the piston housing 132 through the fluid inlet 164, but fluid is not able to flow out of the fluid inlet 164 through unidirectional inlet valve 136.
• unidirectional outlet valve 138 can be attached to the fluid outlet 166 such that fluid is able to flow out of the chamber 170 of the piston housing 132 though the fluid outlet 166, but fluid is not able to flow into the fluid outlet 166 through unidirectional outlet valve 138.

• the spring 186 biases the valve pin 184 against the perimeter of the valve passage in the inlet housing 182 to seal and close the valve 136, 138.
• the movement of the piston 130 draws fluid into and pushes fluid out of the chamber 170 of the piston housing 132.
• a force is asserted against the fluid in the chamber 170 that overcomes the spring biasing force in the unidirectional outlet valve 138 to permit fluid to flow out of the fluid outlet 166 and through the unidirectional outlet valve 138.
• the valve pin in the unidirectional outlet valve 138 returns to the closed position.
• the unidirectional inlet valve 136 remains closed as the fluid is pushed out of the chamber 170.

• the nozzle 120 and/or nozzle connector 140 can have an internal diameter that decreases as the fluid approaches the nozzle opening 121. The decrease in internal diameter can increase the velocity of the fluid exiting the nozzle opening 121.
• the nozzle 120 can be removable such that it can be cleaned by the user when, for example, the user switches fluids.
• a user might utilize a different fluid or cleaning solution for one surface (e.g., hardwood floors) than another (e.g., tile), and switching between the fluids might require the cleaning and/or unclogging of the nozzle 120.
• the nozzle 120 may be removable in any suitable manner, such as by rotating/unscrewing the nozzle 120 from the spray housing 110.
• the unidirectional inlet valve 136 may be connected to the fluid connector 134.
