摘要： Disclosed is a vacuum cleaner including a flow path to guide air suctioned or discharged and a resonator connected to the flow path. The resonator is configured to change a resonance frequency to be canceled. Therefore, when the noise generated by changing operation modes of the vacuum cleaner is changed, the noise may be cancelled by changing the resonance frequency of the resonator.

摘要： The robotic cleaner includes a cleaner body that is movable and a suction unit that is movable relative to the cleaner body in a vertical direction. The suction unit includes an inlet for sucking impurities from the surface to be cleaned, and at least one support unit for spacing the inlet and the surface to be cleaned. With the configuration, the foreign substance suction efficiency from the surface to be cleaned may be improved, and a constant gap between the suction portion and the surface to be cleaned may be maintained.

摘要： By improving a structure of a discharge flow path of a robot cleaner, it may be possible to minimize a loss of a suction force, thereby reducing a noise without deteriorating cleaning efficiency. The robot cleaner includes a fan motor configured to generate a suction force, a first housing in which the fan motor is accommodated, a second housing in which the first housing is accommodated, and a chamber positioned between the first housing and the second housing, wherein a plurality of slits are formed in the chamber.
