8. The cleaner according to claim 7 , wherein the water supply cabinet comprises:
a rotating-shaft support portion configured to rotatably support the spin shaft; and
a partition configured to protrude from the rotating-shaft support portion so as to cover the upper end portion of the water supply reservoir.
9. The cleaner according to claim 1 , further comprising:
a water supply cabinet disposed at the lower side of the body and configured to cover an upper side of the water supply reservoir when viewed from an upper side; and
a water feeder configured to guide water to pass through the water supply cabinet and to be introduced into the water supply reservoir,
wherein the water supply module comprises:
a water tank configured to store the water therein; and
a supply pipe configured to connect the water tank and the water feeder to each other so as to guide movement of the water.
10. The cleaner according to claim 1 , further comprising:
a rotating-shaft support portion, a lower end portion of which is inserted into the water supply space, configured to rotatably support the spin shaft; and
a partition configured to protrude from the rotating-shaft support portion so as to cover an upper end portion of the water supply reservoir.
11. The cleaner according to claim 1 , further comprising a tilting frame disposed on the body so as to be tiltable within a predetermined angular range,
wherein the spin shaft is rotatably coupled to the tilting frame so as to be tiltable integrally with the tilting frame.
12. The cleaner according to claim 11 , further comprising a water feeder fixedly disposed on the tilting frame and configured to guide water so as to be introduced into the water supply reservoir,
wherein the water supply module comprises:
a water tank configured to store the water therein; and
a supply pipe configured to connect the water tank and the water feeder to each other so as to guide movement of the water, the supply pipe flexibly bending depending on tilting of the tilting frame.
13. The cleaner according to claim 1 , wherein: the water supply module comprises a water tank configured to store water therein and a pump configured to apply pressure to the water in the water tank so as to supply the water to the water supply space; and
the cleaner further comprises a controller configured to control the pump to adjust an amount of water to be supplied.
14. A cleaner comprising:
a body forming an external appearance;
a left spin-mop module and a right spin-mop module provided to perform mopping; and
a water supply module configured to supply water to the left spin-mop module and the right spin-mop module,
wherein each of the left spin-mop module and the right spin-mop module comprises:
a rotating plate provided at a lower side of the body;
a mop unit coupled to a lower side of the rotating plate so as to be in contact with a floor;
a spin shaft connected to an upper side of the rotating plate so as to rotate the rotating plate;
a water supply reservoir configured to surround a periphery of the spin shaft and spaced apart from the spin shaft so as to define a water supply space; and
a water feeder configured to guide water so as to be introduced into the water supply reservoir,
wherein the rotating plate forms a water supply hole configured to interconnect the water supply space and the lower side of the rotating plate,
wherein the water supply space is open at an upper side thereof, and is configured so that water is introduced into the water supply space through the upper side of the water supply space.
