The present invention relates to wheels for a robot vacuum cleaner which enables the robot vacuum cleaner to maximize a ground contact length by cross sectional contraction resulting from ground contact pressure in a moving process and to maximize ground contact frictional force, collects remaining water on a rolling surface, and drains the water, such that the robot vacuum cleaner rolls smoothly without slip. In particular, the present invention relates to wheels for a robot vacuum cleaner which has tires made of a foamed synthetic resin and includes contact uneven parts on the outer surfaces of the tires to have draining grooves. Therefore, the present invention enables a contact area with the ground to be maximized by forming the tires of the wheels for the robot vacuum cleaner with the foamed synthetic resin having compressibility, includes the draining grooves to collect and discharge water from the ground, maximizes a frictional area, and facilitates the drain of water to facilitate the rolling action without the slip of wheels. |
