A reconfigurable upright vacuum cleaner has a portable surface cleaning unit removably mounted to an upper portion. The portable surface cleaning unit has a suction motor and an air treatment member. The air treatment member is removably mounted to the portable surface cleaning unit and secured in position by an air treatment member lock. The portable surface cleaning unit is secured in position by a portable surface cleaning unit lock. When the portable surface cleaning unit is mounted to the upper portion and the upper portion is in the storage position, the portable surface cleaning unit actuator is provided on an upper end of the portable surface cleaning unit and the air treatment member release actuator is provided on an upper end of the air treatment member.

The cleaner includes a suction inlet configured to guide air and dusts, a main body including a first cyclone unit configured to separate the air and the dusts, which are suctioned through the suction inlet, from each other, and a dust separation module separably connected to the main body and including a second cyclone unit configured to separate the dusts from the air discharged from the first cyclone unit.

A removable rotatable driven agitator is used in a surface cleaning head and is driven by a drive mechanism that axially engages a driven end of the agitator. The removable rotatable driven agitator may be located in an openable agitator chamber for purposes of removing debris and/or removing the agitator. The openable agitator chamber may be covered by an external cover that is movable between an open position and a closed position. The removable agitator may be secured in the agitator chamber by the external cover. The removable rotatable agitator may have an end cap mounted on a rotatable bushing at a non-driven end and may have a splined driven member at the driven end to engage a splined drive member on the drive mechanism.

The present disclosure discloses a hair scraping plate for a floor brush, and a floor brush and a vacuum cleaner containing the same. The hair scraping plate includes a plate body and a plurality of hair scraping pieces. The hair scraping pieces are located on one side of plate body close to a rolling brush. An area of the hair scraping pieces close to the rolling brush is provided with a scraping area. The scraping area has a first structural plane and a second structural plane. At least part of an area of the first structural plane is inclined to one side close to the second structural plane. When the rolling brush rotates, components located at the same position of a soft scraping layer first approach the first structural plane, and then rotate to a direction away from the second structural plane after abutting against an abutting edge.

The present disclosure discloses a cyclonic propping anti-hair-winding roller brush body, a floor brush and a vacuum cleaner. The cyclonic propping anti-hair-winding roller brush body includes a roller brush main body, at least one cleaning rib is arranged on a surface of the roller brush main body, a flow guide groove is formed in the cleaning ribs, the flow guide groove is formed in a side face of the cleaning ribs in a length direction of the roller brush main body, and the flow guide groove is located on one side facing an area where dirt entering the roller brush main body. When the roller brush main body rotates, the dirt can enter the flow guide groove and turn under an action of the flow guide groove.

A hand vacuum cleaner has a cyclonic stage comprising an openable front wall provided at the front end of the cyclonic stage. A pre-motor filter is positioned in the air flow passage downstream from the cyclone air outlet and rearward of the cyclone sidewall. The pre-motor filter has a diameter in a direction transverse to the cyclone axis that is larger than a diameter of the cyclone air outlet in the direction transverse to the cyclone axis. The pre-motor filter has an outer perimeter defining a volume and the cyclone axis and the motor axis each extend through a centre of the volume. The cyclone axis is generally parallel to the motor axis. When the openable front wall is opened, the front end of the cyclone stage is opened and has an opening, the opening has a diameter in the direction transverse to the cyclone axis, and the rear end of the cyclonic stage has a diameter that is generally equal to the diameter of the opening. The cyclonic stage is removable from a cleaner body which houses the suction motor with the openable front wall in a closed position. When the first cyclonic stage is removed, the pre-motor filter is accessible for removal.

Apparatus and method for receiving and holding debris in a collection chamber of a vacuum cleaner. The collection chamber has an inlet opening through which debris-entrained air enters the collection chamber. When the vacuum cleaner is off, an internal valve prevents debris from leaving the collection chamber through the inlet opening. The internal valve is movable from a first sealed position, in which the internal valve covers the chamber inlet opening, to a second unsealed position in which the internal valve does not cover the chamber inlet opening.
