<p>The present invention relates to a vacuum cleaner to clean a floor and, more specifically, to an electric floor vacuum cleaner which comprises: a housing; and a driving means provided in the housing to rotate a cleaning means, wherein the driving means consists of a first driving member and second driving members provided on both sides of the first driving member. The electric floor vacuum cleaner enables a user to clean a floor with less effort by rotating the second driving members on both sides in opposite directions to prevent power from being concentrated in one direction; has a simple structure by forming threads of different directions on the first driving member to naturally rotate the second driving members in the opposite direction while using one driving motor; and reduces user fatigue by generating the same rotary power in the second driving members with the same rotational speed.</p> |
