    Abstract: A robot cleaner includes a main brush to sweep or scatter dust off a floor, a main brush motor to rotate the main brush, a Revolution Per Minute (RPM) detector to detect an RPM of the main brush motor, and a control unit to determine a type of floor according to the RPM of the main brush motor acquired by the RPM detector and control an operation of the robot cleaner based on the determined type of floor. A carpet mode to clean only a carpet area and a hard floor mode to clean a hard floor area excluding the carpet area are given based on detected information relating to the material of a floor, which enables partial cleaning with respect to a cleaning area selected by a user and adjustment in the number of cleaning operations or the intensity of cleaning according to the material of the floor.

    Abstract: A vacuum cleaner has a discharge flow path and a discharged-air filter optimally positioned to reduce noise. The vacuum cleaner includes a body, a dust collection unit positioned in the body to filter foreign matter, a blower fan unit including a blower fan and a motor to generate suction force, an air vent through which air drawn into the body is discharged, and a discharge flow path to guide the air discharged through a discharge port of the blower fan unit to the air vent. The discharge flow path comprises a space defined between the dust collection unit and the blower fan unit.

    Abstract: A vacuum cleaner having a discharge flow path, which reduces noise generated due to resistance of the flow path, and by a motor. The vacuum cleaner includes a body, a blower fan unit including a blower fan and a motor to generate suction force in the body, an inner case surrounding the blower fan unit and having an inner flow path formed therein, an outer case surrounding the inner case, and a discharge flow path formed between the inner case and the outer case to communicate with the inner flow path. The discharge flow path including a circulation flow path branched from the inner flow path to guide air discharged from the blower fan unit, and a bent flow path branched from the inner flow path to guide the air discharged from the blower fan unit, the air is thereby bent a number of times in the bent flow path.
