A cleaner holder includes a base, a stand coupled to the base and extending upward from the base, a support body coupled to an upper portion of the stand and configured to support a cleaner, and a cleaning module support coupled to the stand and configured to support a cleaning module of the cleaner. The cleaning module may be detachably coupled to an extension tube of the cleaner.

Disclosed are a cleaning apparatus and a control method thereof. A cleaning apparatus according to the present specification, comprising a cleaning module and a main body, comprises: a motor for suctioning air outside the cleaning apparatus; a sensor which is included in the cleaning module and detects a facing distance between the cleaning module and a facing surface while the motor is operating; and a processor which controls the output of the motor on the basis of the facing distance. Thus, even without an additional operation by the user, it is possible to pre-emptively protect a user from injury by a brush that rotates while externally exposed, on the basis of the distance between the cleaning module and the floor surface.

An allergen reduction device may include a body, a dust cup removably coupled to the body, a plurality of agitators rotatably coupled to the body and disposed within respective agitator cavities defined in the body, a suction motor disposed within the body and configured to cause air to flow along corresponding cleaning airflow paths from the agitator cavities into the dust cup, a hot air outlet fluidly coupled to the suction motor, the suction motor being configured to urge the air through the hot air outlet along a heated exhaust airflow path, and a heater positioned within the heated exhaust airflow path between the suction motor and the hot air outlet, the heater being configured to heat the air that is urged from the hot air outlet.

A motor assembly has a motor having a rotor and a stator. An impeller is connected to a rotary shaft of the rotor and a housing is disposed between the impeller and the motor and surrounding an upper side of the motor. A diffuser discharges air, which is suctioned by the impeller, along an outer surface of the housing. A heat dissipation cover covers an outer surface of the motor. The heat dissipation cover includes an inner cover spaced apart from the outer surface of the motor and forming an inside-cover flow channel that air flows through and an outer cover having a diameter greater than that of the inner cover and forming an outside-cover flow channel through which air flows along the outer surface thereof.

A cleaner head for a vacuum cleaning appliance includes an agitator assembly including a cylindrical body configured to rotate about its longitudinal axis; a main body defining an agitator chamber within which is supported the agitator assembly and a suction opening through which a portion of the agitator assembly engages a surface to be cleaned. The main body has opposing ends and a first exhaust channel in fluid communication with the agitator chamber. The main body is configured such that the cross-sectional area of the agitator chamber increases in a direction from one of the opposing ends of the agitator chamber towards the first exhaust channel.

A vacuum cleaner is disclosed. The vacuum cleaner according to the present disclosure includes a main body and a suction nozzle. The suction nozzle includes a housing, a driver, a rotating brush, and a detachable cover. A pressing button is mounted in the housing. The detachable cover is rotated about the rotational axis of the rotating brush to be mounted in the housing. The pressing button selectively blocks rotation of the detachable cover.

A vacuum cleaner is disclosed. The vacuum cleaner according to the present disclosure includes a main body and a suction nozzle. The suction nozzle includes a main housing and a driver. The driver includes a motor and a transmission. The motor is provided behind a rotating brush. The transmission transfers rotational motion of the motor to the rotating brush.

A brushroll for a surface cleaning apparatus includes a brush dowel defining a central rotational axis which extends longitudinally through the brush dowel. The brush dowel includes bristle supports, sweeper supports, and a shroud surface extending between the bristle supports and the sweeper supports. A plurality of bristles protrude from the bristle supports.

A surface cleaning apparatus such as a vacuum cleaner includes a suction source, a recovery container, and a base assembly with at least one agitator within an agitator chamber. The recovery container can be coupled to a separator assembly configured to remove dirt and debris from working fluid through the vacuum cleaner. In addition, a brake assembly can be provided on an upper portion of the base assembly and be configured to engage at least one wheel of the base assembly.
