An autonomous traveling floor cleaner is disclosed that improves cleaning efficiency. A floor cleaner may include a suction nozzle that suctions suction matter collected by a rotary brush, an extension nozzle that suctions suction matter collected by an extension brush, and a collection box for collecting, through an inlet, the suction matter suctioned by the nozzles. The floor cleaner may have an elongated profile. The extension nozzle may be switchable between a retracted posture and a lateral cleaning posture. The extension nozzle in the lateral cleaning posture may be pivotable rearward. The extension nozzle in the lateral cleaning posture may have a protruding end in the width direction to be aligned with an end of a turning range of the floor cleaner in the width direction.

Provided is a robot cleaner including a main body including a suction portion disposed thereon, main wheels for moving the main body, a side brush assembly disposed on the main body and rotating with a rotation shaft perpendicular to a rotation shaft of the main wheels, wherein the side brush assembly includes a housing for forming an exterior of the side brush assembly, a first force transmitter disposed in the housing and rotating by receiving a driving force, a second force transmitter in contact with the first force transmitter to rotate together when the first force transmitter is rotated, and a side brush coupled to the second force transmitter to rotate at the same rotation angle as the second force transmitter.

A robot cleaner includes: a main body configured to travel a cleaning area, and suck foreign substances from a floor of the cleaning area; an image acquisition unit configured to be disposed in the main body, and acquire an image of a certain area of the front of the main body; a first pattern irradiating unit configured to be disposed in the main body, and irradiate light of a first pattern downward into the area; and a second pattern irradiating unit configured to be disposed below the first pattern irradiating unit in the main body, and irradiate light of a second pattern upward into the area, wherein the first pattern includes a first horizontal line and a first vertical line intersecting with the first horizontal line, wherein the second pattern includes a second horizontal line and a second vertical line intersecting with the second horizontal line, wherein when the light of the first pattern and the light of the second pattern are incident on a certain vertical plane, a first intersection point and a second intersection point are first diagonally arranged in a quadrangle defined by the first horizontal line, the first vertical line, the second horizontal line, and the second vertical line.

A suction nozzle, and a vacuum cleaner, and a robot cleaner includes a housing having a suction port formed on a bottom surface thereof and a suction flow path formed on an inside thereof to communicate with the suction port, and a vibration cleaning unit arranged on the suction flow path to pass therethrough air including pollutants that flows in through the suction port, wherein the vibration cleaning unit includes a vibration source, a vibration transfer frame configured to accommodate the vibration source, and a vibration bar configured to receive vibration transferred from the vibration transfer frame to resonate.

A sweeping brush for an automatically moving cleaning device has a rotational axis receptacle for receiving a rotational axis of the cleaning device and at least one bundle receptacle that extends outwardly from a transition area on the rotational axis receptacle, which holds a bristle bundle having a plurality of bristles. The bundle receptacle is arched as viewed in an axial direction of the rotational axis receptacle. In order to optimize known sweeping brushes in terms of their service life and cleaning properties, the bundle receptacle is fabricated out of an elastic material.

An autonomous cleaning robot includes a drive system to support the autonomous cleaning robot above a floor surface, an image capture device positioned on the autonomous cleaning robot to capture imagery of a portion of the floor surface forward of the autonomous cleaning robot, and a controller operably connected to the drive system and the image capture device. The drive system is operable to maneuver the autonomous cleaning robot about the floor surface. The controller is configured to execute instructions to perform operations including initiating, based on a user-selected sensitivity and the imagery captured by the image capture device, an avoidance behavior to avoid an obstacle on the portion of the floor surface.

A vacuum cleaner includes a foot assembly having a suction inlet thereon, a suction source in fluid communication with the suction inlet to produce a working airflow there through, and a dirt container in fluid communication with the suction inlet and suction source. The foot assembly further includes a body defined by a central portion and a pair of extension arms, a rotatable agitator on each extension arm, and a drive assembly configured to counter-rotate the agitators. The counter-rotating agitators are operable to cooperate with the suction source to direct dust and debris towards the suction inlet.

A cleaner head for a vacuum cleaner has a housing, an agitator rotatably mounted within the housing, and first and second debris removal members. The first debris removal member is movable relative to the second debris removal member between a first position in which the first) and second debris removal members are spaced apart to define a debris collection channel, and a second position in which the first and second debris removal members are contiguous or overlapping. Movement of the first debris removal member from the first position toward the second position removes debris from the debris collection channel, and movement of the first debris removal member is governed by rotation of the agitator.

A surface cleaning head with a leading roller may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The surface cleaning head may have dual agitatorsa leading roller and a rotating brush rollwith the leading roller being located in front of the brush roll. The leading roller may have a smaller diameter than the brush roll and may provide a softer cleaning element. The leading roller may also have a bottom portion exposed to the flow path to the suction conduit and at least a top half that is not exposed to that flow path. The leading roller may also float relative to the surface cleaning head and/or may be adjustable relative to the brush roll.

A surface cleaning apparatus comprising a cleaning head and a brushroll. The cleaning head includes a cleaning head body having an agitator chamber including an opening on an underside of the cleaning head body. The brushroll is rotatably mounted to the cleaning head body such that a portion of the brushroll extends below the underside for directing debris into the opening. The brushroll includes an elongated body extending laterally between a first and second end region, a slit opening extending between the first and second end region, angular stationary teeth extending proximate to an edge of the slit opening, and a cutting blade configured to be at least partially received within the slit opening and to move laterally between the first and second end regions. The cutting blade bar includes teeth that are configured to engage with the stationary teeth to cut hair.
