1. A robot cleaner comprising:
- a case forming the external appearance of the robot cleaner;
an agitator rotating and contacting a surface to be cleaned;
a dust collector in which foreign substances are collected; and
a suction unit providing suction force to the dust collector,wherein the agitator is arranged between the dust collector and the suction unit,wherein the suction unit includes a guide duct unit guiding sucked air,wherein the guide duct unit has a first guide duct, a second guide duct arranged in parallel, a first air blower fan provided in the first guide duct, a second air blower fan provided in the second guide duct, and a motor provided at one side of the guide duct unit, so that the first guide duct and the second guide duct maintain separate airflow,wherein the width of an inlet of the guide duct is larger than the height of the inlet of the guide duct,wherein the air blower fans coaxially are connected to a rotary shaft of the motor and rotated, andwherein the rotary shaft is arranged to be parallel with the width of the inlet.

Abstract
Disclosed is a robot cleaner. The robot cleaner includes a case forming the external appearance of the robot cleaner, an agitator rotating and contacting a surface to be cleaned, a dust collector in which foreign substances are collected and a suction unit providing suction force to the dust collector, and the agitator is arranged between the dust collector and the suction unit. Therefore, the robot cleaner reduces loss of suction force generated from the suction unit.

17. A robot cleaner comprising:
-
a case forming the external appearance of the robot cleaner; an agitator rotating and contacting a surface to be cleaned; a dust collector in which foreign substances are collected; and a suction unit providing suction force to the dust collector, wherein air sucked into the dust collector moves so as to become distant from the suction unit, and air discharged from the dust collector moves so as to become close to the suction unit, wherein the suction unit includes a guide duct unit guiding sucked air, wherein the guide duct unit has a first guide duct, a second guide duct arranged in parallel, a first air blower fan provided in the first guide duct, a second air blower fan provided in the second guide duct, and a motor provided at one side of the guide duct unit, so that the first guide duct and the second guide duct maintain separate airflow, wherein the width of an inlet of the guide duct is larger than the height of the inlet of the guide duct, wherein the air blower fans coaxially are connected to a rotary shaft of the motor and rotated, and wherein the rotary shaft is arranged to be parallel with the width of the inlet. - View Dependent Claims (18)
