     DETAILED DESCRIPTION OF THE INVENTION 
     With reference now to the drawings, and in particular to  FIGS. 1 through 6  thereof, a new scrubbing device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral  10  will be described. 
     As best illustrated in  FIGS. 1 through 6 , the electric scrubbing system  10  generally comprises an electric drill  12  that is selectively manipulated and the electric drill  12  has a chuck  14 . The electric drill  12  may be an electric drill of any conventional design to include corded drills and cordless drills. A scrubbing unit  16  is provided and the scrubbing unit  16  is removably coupled to the electric drill  12 . The electric drill  12  rotates the scrubbing unit  16  when the electric drill  12  is turned on. The scrubbing unit  16  is comprised of an abrasive material to remove contaminants from a surface  18 . The surface  18  may be a wall, a floor or other surface and the surface  18  may be comprised of wood, tile, carpet, steel or other material used for construction purposes. 
     The scrubbing unit  16  comprises a brush  20  that has a first end  22 , a second end  24  and an outer surface  26  extending therebetween. The outer surface  26  is continuous such that the brush  20  has a cylindrical shape. The outer surface  26  tapers inwardly between the first end  22  and the second end  24  and the outer surface  26  has a depression  28  near a middle of the brush  20  to enhance gripping the brush  20 . A pair of ridges  30  extends outwardly from the outer surface  26  and each of the ridges  30  is continuous to enhance gripping the brush  20 . 
     The brush  20  has an aperture  32  extending through the first end  22  and the second end  24 . The first end  22  has a well  34  extending toward the second end  24  and the well  34  is aligned with the aperture  32 . The well  34  has a lower bounding surface  36 . A sleeve  38  is positioned on the second end  24  of the brush  20  and the sleeve  38  is oriented to be aligned with the aperture  32 . The sleeve  38  may be a threaded nut or the like. The sleeve  38  has a plurality of intersecting outer surfaces  39  and the chuck grips the intersecting outer surfaces  39 . 
     A bolt  40  is slidably inserted through the aperture  32  in the brush  20  and the bolt  40  threadably engages the sleeve  38 . In this way the sleeve  38  is retained on the brush  20 . The bolt  40  engages the lower bounding surface  36  of the well  34  to tighten the sleeve  38  against the brush  20 . The sleeve  38  engages the chuck  14  on the electric drill  12  when the sleeve  38  is tightened against the brush  20 . Thus, the brush  20  is rotatably coupled to the electric drill  12 . 
     A plurality of bristles  42  is provided and each of the bristles  42  is coupled to and extends away from the first end  22  of the brush  20 . The bristles  42  are spaced apart from each other and are distributed on the first end  22 . Each of the bristles  42  has a distal end  44  with respect to the brush  20  to frictionally engage the surface  18 . Moreover, each of the plurality of bristles  42  has an increasing length with respect to each other between the outer surface  26   d  of the brush  20  and the well  34 . Thus, the distal end  44  corresponding to each of the bristles  42  defines a dome. 
     In use, the bolt  40  is extended through the brush  20  to threadably engage the sleeve  38 . The bolt  40  is tightened and the sleeve  38  is tightened against the brush  20 . The sleeve  38  is inserted into the chuck  14  on the electric drill  12 . The electric drill  12  is manipulated to position the bristles  42  against the surface  18 . The electric drill  12  is turned on and the brush  20  abrades the contaminants from the surface  18 . In this way the brush  20  cleans the surface  18 . 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, system and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure. 
     Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
