A cleaner comprises a housing having a dust collection chamber formed in the housing and configured to open and close, a main body movable relative to the housing between a first position whereby the main body closes the dust collection chamber and a second position whereby the main body opens the dust collection chamber, and a motor filter mountable to and demountable from the main body, wherein the main body includes a fan motor unit to generate a suction force, and a shutter device mountable into the main body and configured to open and close a flow path between the motor filter and the fan motor unit.

Provided is a cleaner system, according to one embodiment of the present disclosure, which comprises a terminal and a cleaner provided to be capable of wireless communication with the terminal. The cleaner comprises: a main body; a cleaning unit provided in the main body; a communication unit that wirelessly communicates with an external terminal; a control unit for processing information on the cleaner; and a battery for providing power, wherein the terminal visually provides information transmitted from the cleaner to a user. According to embodiments of the present disclosure, it is possible to enable a user to easily grasp information on the cleaner even if the user does not pay great attention to the cleaner, and to catch the user's attention by means of an alarm.

A hand vacuum cleaner has an openable air treatment stage. The air treatment stage has a lower openable portion that is moveably mounted to a forward portion of the pre-motor filter housing.

A surface cleaning apparatus comprises a cyclone positioned in an air flow path having a tangential air inlet with an inlet end, an outlet end, a cross-sectional flow area in a direction of flow through the tangential air inlet, a height in a direction of the cyclone axis of rotation and a width in a direction transverse to the height of the tangential air inlet. The air flow path comprises an air flow conduit at the inlet end of the tangential inlet having a cross-sectional flow area in a direction transverse to a direction of flow through the air flow conduit. The cross-sectional flow area of the tangential air inlet is greater than the cross-sectional flow area of the air flow conduit and one of the width and height of the tangential air inlet is greater than the other of the width and height of the tangential air inlet.

A motor is provided that reduces noise and vibration, and a method is provided for manufacturing the motor and a cleaner having the motor. The motor includes a stator including a plurality of teeth that are spaced apart from each other in a predetermined interval in a circumferential direction and a coil that is wound around the plurality of teeth, a rotor that is disposed inside the stator, and a cage that is disposed in at least one of a plurality of slots that are formed between the plurality of teeth. The cage is configured to include a flow path to inject a bonding agent into at least one slot.

A method of charging a rechargeable battery includes positioning a rail of the rechargeable battery into a groove defined by a housing of a battery charger, and positioning a switch between an ON position and an OFF position. The switch is positioned in the ON position when the rechargeable battery is connected to the charger and in the OFF position when the rechargeable battery is disconnected from the charger. The housing includes a barrier extending across the groove to prevent movement of the switch to the ON position when the rechargeable battery is disconnected from the charger. The method further includes conducting electrical current to the rechargeable battery through an electrical connection interface.
