 a power supply unit to supply power to the suction force generating unit, and 
   wherein the suction force generating unit is disposed between the suction port and the dust separating unit so that the drawn air and dust passes through the suction force generating unit before being introduced into the dust separating unit.   
   
   
       2 . The stick type vacuum cleaner of  claim 1 , wherein the suction force generating unit comprises:
 an impeller exposed to a passage defined between the suction port and the dust separating unit, the impeller being configured to generate the suction force by rotational movement; and   a suction motor to receive a power from the power supply unit and rotate the impeller.   
   
   
       3 . The stick type vacuum cleaner of  claim 1 , wherein the dust separating unit comprises:
 a cyclone chamber to separate dust from the air and dust drawn through the suction port by using a centrifugal force; and   a dust collecting chamber to accommodate the dust separated from the cyclone chamber.   
   
   
       4 . The stick type vacuum cleaner of  claim 3 , wherein the dust separating unit comprises:
 a cyclone dust separating unit in which the cyclone chamber and the dust collecting chamber are arranged in parallel, in a manner such that a cyclone inlet is formed on a first end and the cyclone chamber and the dust collecting chamber are open in a second end; and   a side cover to cover the second side of the cyclone dust separating unit, the side cover comprising an air discharge pipe to guide the air to be discharged from the cyclone chamber.   
   
   
       5 . The stick type vacuum cleaner of  claim 4 , wherein the dust separating unit comprises:
 a filter member formed on an outer surface of the side cover to filter remaining dust from the air being discharged from the cyclone chamber; and   a filter support member removably formed on the outer surface of the side cover to support the filter member formed on the side cover.   
   
   
       6 . The stick type vacuum cleaner of  claim 5 , wherein the filter support member comprises at least one air passing hole. 
   
   
       7 . The stick type vacuum cleaner of  claim 4 , wherein an upper side of the cyclone dust separating unit is made out of a transparent material to enable a user to see the cyclone chamber and the dust collecting chamber therethrough. 
   
   
       8 . The stick type vacuum cleaner of  claim 1 , wherein the casing part comprises a dust separating unit chamber so that the dust separating unit is removably housed in the dust separating unit chamber. 
   
   
       9 . The stick type vacuum cleaner of  claim 1 , wherein the suction port assembly further comprises:
 a rotatable brush movably formed in the suction port; and   a rotatable brush motor to drive the rotatable brush.   
   
   
       10 . The stick type vacuum cleaner of  claim 9 , wherein the rotatable brush motor receives power from the power generating unit. 
   
   
       11 . The stick type vacuum cleaner of  claim 1 , wherein the stick part comprises:
 an engaging part engaged to the first side of the suction port assembly;   a stick type extension part extended from the engaging part; and   a handgrip formed on one end of the stick-type extension part.   
   
   
       12 . The stick type vacuum cleaner of  claim 1 , wherein the power supply unit comprises a battery removably disposed inside the casing part. 
   
   
       13 . A stick type vacuum cleaner comprising:
 a stick-type extension part having a handgrip part formed at a first end thereof;   a casing part comprising a suction port and stick engaging part, the stick engaging part being configured to engage a second end of the stick-type extension part;   a suction force generating unit inside the casing part to generate a suction force, the suction force being configured to draw in air and dust from an object being cleaned through the suction port;   a dust separating unit to separate and collect the dust from the air and dust; and   a battery removably inside the casing part, the battery being configured to supply power to the suction force generating unit, wherein the suction force generating unit is disposed between the suction port and the dust separating unit so that the drawn air and dust passes through the suction force generating unit before being introduced into the dust separating unit.   
   
   
       14 . The stick type vacuum cleaner of  claim 13 , wherein the suction force generating unit comprises:
 an impeller exposed to a passage defined between the suction port and the dust separating unit, the impeller being configured to generate the suction force by rotational movement; and   a suction motor to receive a power from the battery and rotate the impeller.   
   
   
       15 . The stick type vacuum cleaner of  claim 13 , wherein the dust separating unit comprises:
 a cyclone chamber to separate dust from the air and dust drawn through the suction port by using a centrifugal force; and   a dust collecting chamber to accommodate the dust separated from the cyclone chamber.
