Abstract
A robot vacuum cleaner includes a main body that moves along a surface, draws in dust from the surface, filters the dust, and discharges air. A water tank is detachably mounted on a lower surface of the main body, and a damp cloth is mounted to the water tank. The water tank stores water in a filling space and supplies water from the filling space through a water supply unit mounted on a lower surface of the water tank to the damp cloth. An air inlet is formed on an upper surface of the water tank. An air inflow member selectively opens the air inlet to allow outside air to flow into the filling space when the main body moves, and closes the air hole when the main body stops moving.

A robot vacuum cleaner comprising:
- a main body running along a surface to be cleaned, the main body being configured to suction and filter dusts on the surface to be cleaned and then discharge air;
- a water tank unit which is detachably mounted on a bottom surface of the main body and on which a damp cloth is mounted;
- a filling space formed in the water tank unit, the filling space being configured to store water to be supplied to the damp cloth;
- a water supply unit mounted on a bottom surface of the water tank unit, the water supply unit being configured to supply the water within the filling space to the damp cloth;
- an air inlet which is formed in a top surface of the water tank unit and in which an air hole through which external air is introduced into the filling space is formed;
- and
- an air inflow control member configured to open the air hole when the main body runs and cover the air hole when the main body is stopped.
