A rotatable agitator is used in a surface clearing head of a surface cleaning apparatus. The agitator is coupled to the cleaning head at least partially within an agitator chamber and is rotated about a pivot axis. The agitator includes an elongated agitator body and a hair migration portion. The hair migration portion includes a continuous row of bristles and a sidewall. The continuous row of bristles and sidewall are at least partially revolved around and extend along at least a portion of the pivot axis from one of a collection area or a first end region of the agitator and either another collection area or a second end region of the agitator. The sidewall extends substantially parallel to the continuous row of bristles within the hair migration portion. The continuous row of bristles and sidewall are configured to reduce hair from becoming entangled in the bristles and to migrate hair towards the collection area or the first end region of the agitator.

A vacuum cleaner tool having a brush head, a rotatable duct, and a hinge. The rotatable duct is configured to receive a hose or wand and rotates about the hinge relative to the brush head, between a use position and storage position. In a storage position, the rotatable duct extends generally parallel, or in-line with the brush head and, in a use position, the rotatable duct extends generally perpendicular to the brush head. The vacuum cleaner tool may removably attach to the vacuum cleaner via a release on one end of the brush head interacting with a fixed catch on the vacuum cleaner.

A brushroll for a vacuum cleaner includes a brush dowel having a plurality of bristles and a drive motor within the brush dowel for rotating the brush dowel in a first direction of rotation, wherein an armature and motor shaft of the drive motor counter-rotates in a second direction of rotation.

An autonomous coverage robot includes a chassis, a drive system configured to maneuver the robot, and a cleaning assembly. The cleaning assembly includes a cleaning assembly housing and at least one driven sweeper brush. The robot includes a controller and a removable sweeper bin configured to receive debris agitated by the driven sweeper brush. The sweeper bin includes an emitter disposed on an interior surface of the bin and a receiver disposed remotely from the emitter on the interior surface of the bin and configured to receive an emitter signal. The emitter and the receiver are disposed such that a threshold level of accumulation of debris in the sweeper bin blocks the receiver from receiving emitter emissions. The robot includes a bin controller disposed in the sweeper bin and monitoring a detector signal and initiating a bin full routine upon determining a bin debris accumulation level requiring service.

Disclosed is a vacuum cleaner having an improved structure for preventing hair or foreign substances from being caught in a wheel. The vacuum cleaner includes a suction nozzle having a suction passage for cleaning a surface to be cleaned by a suction force and a wheel assembly accommodated in the suction nozzle and configured to be rotatable. The wheel assembly includes a wheel and a rotating shaft to rotatably support the wheel. The rotating shaft is inclined relative to a bottom surface of the suction nozzle.

A vacuum cleaner includes a housing, suction path, a motor, and a base. The suction path is in fluid communication with the housing. The motor creates flow through the suction path. The base includes a first inlet and a second inlet. The first inlet is in fluid communication with the suction path. The second inlet is adjustable between a first position allowing fluid to flow through the second inlet and a second position preventing at least a portion of fluid from flowing through the second inlet. The second inlet may include a door moveable between the first position and the second position to adjust the amount of airflow.

The present invention relates to the technical field of cleaning, in particular to a cleaning appliance, which comprises a cleaning appliance body. The cleaning appliance body includes a housing, two brush rollers disposed at the bottom of the housing, a drive mechanism disposed in the housing and configured to drive the two brush rollers to rotate, and a dust collector disposed on the housing; a suction port of the dust collector is disposed between the two brush rollers; and both rotation directions of the two brush rollers direct towards the suction port. The cleaning appliance provided by the present invention adopts a combined structure of the two brush rollers and the dust collector; both rotation directions of the two brush rollers direct towards the suction port; dust, particulate waste or flocks are gathered; the waste is sucked into the dust collector through the suction port between the two brush rollers.

There is provided a robot cleaner having an improved dust-collecting capability and an improved suction force and capable of being manufactured in a small size. The robot cleaner includes a main body comprising a fan motor and having a suction port provided in one side thereof; a plurality of cyclone units configured to separate foreign substances in air suctioned through the suction port; and a plurality of suction flow paths connecting the plurality of cyclone units and the suction port.

A cleaning apparatus includes an end cap assembly for use with an agitator. The end cap assembly includes a stationary end cap, a rotating end cap, and a fragmentor. The stationary end cap is secured to and stationary with respect to a housing of the cleaning apparatus. The rotating end cap is coupled to the agitator and rotates with the agitator relative to the housing. The stationary and rotating end caps define a gap extending radially inward therebetween. The fragmentor is disposed within the gap and is configured to break debris which enters the gap into smaller pieces. The fragmentor may be disposed on a surface of the stationary end cap facing towards the rotating end cap and/or on a surface of the rotating end cap facing towards the stationary end cap. The fragmentor may include a cutting blade and/or an abrasive surface.

Disclosed is a vacuum cleaner. The vacuum cleaner includes a suction nozzle housing, an agitator provided within the suction nozzle housing, and a suction channel guiding air sucked into the suction nozzle housing to a dust collector, the agitator includes a body rotatably installed in the suction nozzle housing, brush members disposed on the body in parallel with the center of rotation of the body and combined with the body so as to be fixed, and auxiliary members disposed on the body in parallel with the center of rotation of the body and combined with the body so as to be movable when the body is rotated, and a protrusion overlapping with parts of the brush members and contacting the brush members when the body is rotated is provided in the suction channel.
