Drum module for cleaner and cleaner including the same

A cleaner comprising:

• a main body;
• and
• a suction head connected to the main body to suck foreign objects into the main body, the suction head comprising:
• a housing including a suction port through which the foreign objects are sucked into;
• and
• a drum module rotationally coupled to the housing to scatter the foreign objects sucked through the suction port so that the scattered foreign objects are drawn into the housing, and
• wherein the drum module comprises:
• a drum body defining external appearance of the drum module;
• a first blade coupled to an outer circumferential surface of the drum body to contact and scatter the foreign objects;
• a second blade separated from the first blade in a circumferential direction of the drum body, and having a higher density than a density of the first blade;
• and
• a mass compensation rib arranged to be adjacent to the first blade to make a mass center of the drum module closer to a rotation center,
• wherein the second blade protrudes further than the first blade in a radial direction of the drum body.

• a first blade;
• a second blade having a greater mass than a mass of the first blade;
• and
• a mass compensation rib arranged on the outer surface to make a mass center of the drum module closer to a rotation center of the drum module,
• wherein the second blade protrudes further than the first blade in a radial direction of the drum body.
