     DETAILED DESCRIPTION 
     The invention will be understood from the following detailed description of embodiments of the invention, which are meant to be descriptive and not limiting. For the sake of brevity, some well-known features are not described in detail. 
     The reference numbers have been used to point out elements in the embodiments described and illustrated herein, in order to facilitate the understanding of the invention. They are meant to be merely illustrative, and not limiting. Also, the foregoing embodiments of the invention have been described and illustrated in conjunction with systems and methods thereof, which are meant to be merely illustrative, and not limiting. 
       FIG. 1  is in an exploded perspective view of a brushing accessory according to one embodiment of the invention. 
     A brushing accessory  10  such as for soaping, according to one embodiment of the invention, includes a motorized member  50 A and a brushing member  50 B, including holes  26 A and  26 B. 
       FIG. 2  is the exploded perspective view of  FIG. 1  from another angle of view. 
     Connecting motorized member  50 A to brushing member  50 B inserts pin  24 A of motorized member  50 A into hole  26 A and pin  24 B into hole  26 B of brushing member  50 B. 
       FIG. 3  is a sectional view of the motorized and brushing members of  FIG. 1 . 
     A motor  32  rotates a central cog  54 C. 
     Referring again to  FIG. 2 , equal cogs  54 A and  54 B are interlaced to central cog  54 C, one opposite to the other, thus they rotate at equal speeds. 
     The interlacing of cogs  54 A and  54 B to central cog  54 C disposes pins  24 A and  24 B at the same side. 
       FIG. 4  is a top view of the opposing cogs at the state of  FIG. 3 . 
     Pins  24 A and  24 B are shown disposed at the left, enumerated  64 A. 
       FIG. 5  is the top view of the opposing cogs upon rotating  90  degrees. 
     Since cogs  54 A and  54 B are equal, and pins  24 A and  24 B are equally distanced  58 , once pin  24 A is disposed up enumerated  64 B, pin  24 B as well is disposed up, and the virtual line  60  therebetween maintains its angle, to the angle of the state of  FIG. 5 , being horizontal according to the examples. 
       FIG. 6  depicts 4 locations of one of the pins of  FIG. 2 , and the disposition of the brush member for each of the dispositions. 
     Pins  24 A and  24 B extend from cogs  54 A and  54 B respectively, and having the equal distances  58  between center  20  and center  22  of the cogs. 
     In case pin  24 A is disposed at location  64 A, brush  18  is disposed at zone  62 A; in case pin  24 A is disposed at location  64 B, brush  18  is disposed at zone  62 B; in case pin  24 A is disposed at location  64 C, brush  18  is disposed at zone  62 C; and in case pin  24 A is disposed at location  64 D, brush  18  is disposed at zone  62 D. 
     Zone  62 A is left to zone  62 C, thus providing a left to right back and forth motion to brush  18 ; zone  62 B is above zone  62 D, thus providing a top to bottom back and forth motion to brush  18 ; and zone  62 A is below and left to zone  62 B, thus providing a 45 degrees back and forth motion to brush  18 . Considering the states between these 4 shown states, brush  18  moves back and forth in all directions. 
     This brushing movement is further advantaged in applying equal distances and speeds to all points of the user&#39;s body, being in contrast to symmetric rotating of a brush, or even to eccentric rotating of a brush applying a higher distance and speed away from the center of the rotation. 
       FIG. 7  is a side view of the brushing accessory of  FIG. 1  including an elevator. 
     Brushing accessory  10  may include an elevator  44 , for brushing various heights. 
       FIG. 8  is a front view of the brushing accessory of  FIG. 7 . 
     The user may move left and right in relation to the elevator of  FIG. 7 . 
     Thus, in one aspect, the invention is directed to a brushing accessory ( 10 ), including:
         a brushing member ( 50 B), including a brush ( 18 ); and   a motorized member ( 50 A), including a motor ( 32 ) including a first cog ( 54 C), and including a second cog ( 54 A) interlaced with the first cog ( 54 C),       where the diameter of the second cog ( 54 A) is of several centimeters,   thereby the second cog ( 54 A) moves the brush ( 18 ) several centimeters at least back and forth.   

     The brushing accessory ( 10 ) may further include:
         a third cog ( 54 B) interlaced with the first cog ( 54 C),       thereby the back and forth moving of the brush is along all directions.   

     Centers of ( 22 , 20 ) of the first, second and third cogs may be disposed along a virtual line ( 60 ). 
     The second ( 54 A) and third ( 54 B) cogs may be equal. 
     The brush ( 18 ) may be connected to a point ( 24 A) of the second cog ( 54 A) and to a point ( 24 B) of the third cog ( 54 B),
         and the points ( 24 A, 24 B) may be equally distanced ( 58 ) each from the center ( 22 ) of that cog.       

     The interlacing of the second ( 54 A) and third ( 54 B) cogs may dispose the points ( 24 A, 24 B) at an equal side.
