       2 . The power floor cleaning apparatus as claimed in  claim 1 , wherein said handle comprises a handle body formed of a plurality of rod members that are detachably connected to one another through a respective screw joint, said handle body having a top end and a bottom end, a handle grip at the top end of said handle body, an extension rod axially movable in and out of the bottom end of said handle body, a chuck provided at the bottom end of said handle body and adapted to lock said extension rod, and a swivel connector provided at an outer end of said extension rod and coupled to said housing.  
   
   
       3 . The power floor cleaning apparatus as claimed in  claim 1 , further comprising a power switch mounted inside said top cover shell of said housing for power on/off control, a spring member mounted on said top cover shell of said housing corresponding to said power switch, and a button supported on said spring member for pressing by the user t 5 o switch on/off said power switch.  
   
   
       4 . The power floor cleaning apparatus as claimed in  claim 1 , further comprising a locating plate mounted inside said top cover shell and supporting one end of the axle of said first sweeper.  
   
   
       5 . The power floor cleaning apparatus as claimed in  claim 1 , further comprising a plurality of rollers pivotally mounted in a bottom side of said bottom cover shell of said housing for moving.  
   
   
       6 . The power floor cleaning apparatus as claimed in  claim 1 , wherein said housing further comprises a bumper mounted around the connection area between said top cover shell and said bottom cover shell.  
   
   
       7 . The power floor cleaning apparatus as claimed in  claim 1 , wherein said actuator is a motor.  
   
   
       8 . The power floor cleaning apparatus as claimed in  claim 1 , wherein said cylindrical sweeper body of said second sweeper is comprised of a plurality of plate-like brush elements arranged in parallel, said plate-like brush elements each having a plurality of brush portions extending in different directions.  
   
   
       9 . The power floor cleaning apparatus as claimed in  claim 1 , wherein said cylindrical sweeper body of said second sweeper comprises a roller-like brush and a frame holding said roller-like brush, said frame comprising an upper clamping plate and a bottom clamping plate fastened to said upper clamping plate to hold down said roller-like brush.  
   
   
       10 . The power floor cleaning apparatus as claimed in  claim 1 , wherein said second sweeper further comprises a guard mounted inside said housing and covered over a top side of said cylindrical sweeper body.  
   
   
       11 . The power floor cleaning apparatus as claimed in  claim 1 , further comprising a power supply unit formed of a storage battery and adapted to provide the necessary working voltage to said actuator.  
   
   
       12 . The power floor cleaning apparatus as claimed in  claim 1 , wherein said cylindrical sweeper body of said second sweeper is comprised of a plurality of rolls connected in series and respectively covered with a layer of hook material for the fastening of a cloth pad.
