Disclosed is a robot cleaner which adjusts a suction area of air suctioned into a suction port through a shutter and a shutter driving device configured to operate the shutter, so that a flow rate of air is adjusted, thus more effectively suctioning dust in the air by using a fan motor having a fixed capacity.

A robot cleaner comprising: a cleaner body including a controller, the cleaner body having a dust container accommodation part formed therein; a wheel unit mounted in the cleaner body, the wheel unit of which driving is controlled by the controller; and a dust container detachably coupled to the dust container accommodation part, wherein a first opening and a second opening are disposed at the same height in an inner wall of the dust container accommodation part, wherein the dust container includes: an entrance and an exit, disposed side by side along the circumference of the dust container, the entrance and the exit, respectively communicating with the first opening and the second opening when the dust container is accommodated in the dust container accommodation part; and a flow separating part extending downwardly inclined along the inner circumference of the dust container.

Disclosed is a cleaner station including a first station with which a hand vacuum cleaner can be combined and a second station with which a robotic vacuum cleaner can be combined. The first station may include a first suction portion which sucks dust from a dust bin of the hand vacuum cleaner. The second station may include a second suction portion which sucks dust from a dust bin of the robotic vacuum cleaner. The cleaner station may include a dust inlet where the dust sucked by the first suction portion and the second suction portion is discharged. The cleaner station may include a dust storage box which communicates with the dust inlet and receives the dust sucked by the first suction portion and the second suction portion.

The present invention is directed to a vacuum including a dust extraction system. The system includes a filter assembly, an airflow generation assembly, and valve assembly. The airflow generation assembly is configured to draw contaminated air toward the filter assembly and exhaust filtered air as a discharge stream. The filter assembly is configured to remove contaminants from the contaminated airflow by capturing particulate material suspended within the airflow. The valve assembly is configured to selectively direct filtered airflow into the filter assembly such that the filtered air stream cleans the filter.

An accessory tool for a vacuum cleaner includes a conduit and a nozzle. The conduit includes a first end coupled to the vacuum cleaner and a second end opposite the first end. The nozzle is coupled to the second end and includes a first portion with a first set of teeth and a first channel with an opening opposite the first set of teeth. The nozzle also includes a second portion with a second set of teeth and a second channel with an opening opposite the second set of teeth. The first set of teeth interlock with the second set of teeth, and are configured to cause the first portion and the second portion to pivot together relative to the conduit between a closed position and an open position. The nozzle is movable along an outer surface of the conduit from the second end toward the first end.

A suction nozzle for a vacuum cleaner, the suction nozzle comprising a suction chamber, an outlet duct extending from the suction chamber for connection to a vacuum source on the vacuum cleaner, a soleplate for supporting the nozzle on a carpeted floor, a suction opening in the soleplate which opens into the suction chamber, and a valve which can be manually operated to open or close a bleed path through the front of the nozzle into the suction chamber, the bleed path being defined by a channel formed on the underside of the soleplate which is fluidly connected to the outlet duct, the channel terminating in an entrance slot on the front of the nozzle for admitting debris as the suction nozzle is pushed in a forward direction, the channel defining a throat downstream of the entrance slot, the throat having a smaller cross-sectional area than the entrance slot.

A robot cleaner comprising: a cleaner body; a suction unit sucking air containing dust to be introduced into the cleaner body; and a dust container detachably coupled to the cleaner body, the dust container collecting dust filtered from the air introduced into the cleaner body, wherein the dust container includes: an external case including at least one cyclone filtering dust in air introduced into the dust container; an upper case coupled to an upper portion of the external case, the upper case including an upper opening corresponding to a space into which air passing through the cyclone is discharged; an upper cover detachably coupled to the upper case to open/close the upper opening; and a filter mounted on a rear surface of the upper cover, the filter covering the discharged space of the air passing through the cyclone when the upper cover is coupled to the upper case, to filter dust in the air passing through the cyclone.

Disclosed are a dirt suction guide device and a cleaner comprising the same. The disclosed cleaner comprises: a cleaner body for generating a suction force; a flexible hose connected to the cleaner body; an extension tube connected to the flexible hose; and a dirt suction guide device separately coupled to the extension tube, wherein the dirt suction guide device comprises a body, a movable portion, which is connected to one side of the body, and which is coupled to be able to slide with regard to the body, and a connecting portion, which is connected to the other side of the body, and which connects the body to the extension tube, and the body is hinge-coupled such that the same can selectively maintain and change an angle with regard to the extension tube.

Disclosed are a fan motor and a vacuum cleaner which include a blowing fan and a plurality of diffuser blades disposed at a radially outer side of the blowing fan and circumferentially spaced apart from each other. Outer end portions of the plurality of diffuser blades include a spoiler portion formed obliquely to an outward direction with respect to an extending direction of the diffuser blades, so that a flow separation of air flowing across an outer surface of the diffuser blade is reduced. Accordingly, the suction force of the fan motor increases.

A autonomous cleaner includes: a cleaner body including a wheel unit for autonomous traveling; a suction unit provided to protrude from one side of the cleaner body, the suction unit sucking air containing dust; a sensing unit provided at the one side of the cleaner body; a dust container accommodated in a dust container accommodation part formed at the other side of the cleaner body, the dust container collecting dust filtered from sucked air; and a dust container cover hinge-coupled to the cleaner body to be rotatable, the dust container cover being provided to cover a top surface of the dust container when the dust container cover is coupled to the dust container.
