1. A vacuum cleaner comprising:
- a suction assembly;
a dust collecting chamber collecting air and dust through an air path, wherein the air path connects the suction assembly to a connecting pipe by a negative pressure;
a driving portion generating the negative pressure and activated by manipulating a driving switch disposed on a handle portion;
a floor cloth rotatably driven in the suction assembly to clean a cleaning surface, the floor cloth arranged in a plane;
a rotary member rotatably disposed on a lower end of the suction assembly, for supporting the floor cloth, wherein the floor cloth rotates in a plane substantially parallel to the cleaning surface and the plane of the floor cloth;
rotary driving means controlled by the manipulation of the driving switch, for supplying a driving force to rotate the rotary member;
power supplying means for supplying an electric signal generated by the manipulation of the driving switch to the rotary driving means; and
wherein the rotary driving means includes a bi-directional rotary motor having a air of rotary shaft portions;
one of the air of rotary shaft portions being formed on each side of the rotary motor and simultaneously rotating with each other by the power supplied from the power supply means; and
the rotary shaft portions connecting to a power transmission unit for transmitting a driving force of the rotary shaft portions to the rotary member.

Abstract
A floor cloth employed in a suction assembly of a vacuum cleaner for cleaning impurities on a cleaning surface, and an apparatus of the vacuum cleaner for rotatably driving the floor cloth. The rotatable floor cloth driving apparatus includes a rotary member rotatably disposed on a lower end of the suction assembly for supporting the floor cloth, and a rotational driving portion on-off controlled by a manipulation of a driving switch for providing a rotational driving force for rotating the rotary member on on-state. Accordingly, while drawing in air and impurities, the vacuum cleaner can also remove impurities stuck on the cleaning surface with the floor cloth.
