First, the various components are obtained. Grip 13, motor housing 154, mop support frame 52, drive shaft 158, scrubber support frame 74 and cleaning member base plates 57 and 59 may be injection molded to conform to the structures shown in FIGS. 1-5. Handle 12, cleaning member actuator 26, lever arm 35, dual squeeze arms 40 and 42, cleaning member support plates 54 and 56, spring member 58 and screws are conventional components known to those of skill in the art. Motor 156, wiring and scrubber actuator 28 may be purchased from a hardware or electronics store.

Second, the various components are assembled. In no particular order, mop support frame 52 is provided. Scrubber bracket 76 is secured to mop support frame 52 by aligning the apertures 101 in mop support frame 52 with the apertures 136 of scrubber bracket 76 and inserting a screw or other fastener. Squeeze members 40 and 42 and lever arm 35 are provided. As is customary, ends 44 and 46 of squeeze members 40 and 42 are inserted through openings in mop support frame 52 and cleaning member support plates 54 and 56 are secured to mop support frame 52. Drive shaft 158 is positioned within central channel 98 of mop support frame 52. Motor 156 is positioned within motor housing 154, which is affixed to lower end 16 of handle 12. Rotating pin 159 of motor 156 is positioned within central opening 168 of drive shaft 158. After scrubbers 22 and gears 106 are secured to scrubber support frame 74, apertures 118 and grooves 123 in scrubber support frame 74 are aligned with corresponding countersinks and elongated projections 103 in mop support frame 52 for attachment. Cleaning member 20 is positioned on cleaning member support plates 54 and 56, with dual screws 64 and 66 of cleaning member 20 projecting out of openings 68 and 70. Guard 34 is secured to mop support frame 52. Cover 32 is positioned over mop support frame 52 and edge 80 of cover 32 is secured to groove 145 of guard 34.

In operation, butterfly mop 10 can be used in either of a mopping or scrubbing mode. After mop 10 is assembled, a user can clean flat smooth surfaces through a mopping action with cleaning member 20. After cleaning member accumulates 20 dirty water, downward pressure on cleaning member actuator 26 pivots cleaning member support plates 54 and 56 and base plates 57 and 59, compressing a portion of cleaning member 20 to remove excess water. Mop 10 can also be used for more concentrated scrubbing action, (e.g., when a deep-seated or ingrained soiled area is encountered), by tilting handle 12 downwardly to contact scrubber members 22 with the surface to be cleaned, turning on motor 156 with scrubber member actuator 28 and moving scrubber members 22 over the targeted area.

Variations, modifications and other implementations of what is described herein will occur to those of ordinary skill in the art without departing from the spirit and scope of the invention. Accordingly, the invention is in no way limited by the preceding illustrative description.
