A vacuum cleaner includes an improved dual-action filter cleaning mechanism using both a rotational flicking action and a vertical shaking action. A debris removal assembly of the vacuum cleaner can include a filter assembly having a first filter and a second filter arranged in a nested configuration, and a filter cleaning mechanism configured to impart a combination of vertical shaking of the first filter and rotational flicking of the second filter. The filter cleaning mechanism can include a camming mechanism configured to simultaneously move the first filter along the axis and rotate the first filter about the axis while the second filter remains stationary.

A rotor has magnetic poles and a stator has the same number of teeth. Each tooth has first and second side portions in first and second directions in a circumferential direction, and a tooth tip facing the rotor. First and second protruding portions protrude in the first and second directions from the first and second side portions on the tooth tip side. The tooth tip has a first end having a gap G1 with the rotor and a second end having a gap G2 (>G1) with the rotor. A reference line passes through a rotation axis and perpendicular to a radial straight line passing through a middle position between both side portions. From the reference line, a distance D1 a border between the first protruding portion and the first side portion is longer than a distance D2 to a border between the second protruding portion and the second side portion.

A stand for a cleaner is capable of holding and charging selectively a cleaner body or a battery. The stand for a cleaner includes a first charging terminal configured to be electrically connected to a cleaner body, a second charging terminal configured to be electrically connected to a battery, and a battery guide configured to guide the battery. The battery guide guides the cleaner body to be connected to the first charging terminal when the battery is mounted to the cleaner body, and is configured to guide the battery to be connected to the second charging terminal when the battery is separated from the cleaner body.

A vacuum cleaner may include a suction motor and a cyclonic separator fluidly coupled to the suction motor. The cyclonic separator may include a chamber and a first and a second vortex finder extending within the chamber. The first and second vortex finders may extend from opposing sides of the chamber.

Provided is a charging device for charging a wireless manual cleaner and a robot cleaner. The charging device includes a first charger comprising a first charging terminal connected to a charging terminal of the manual cleaner, and a first transceiver configured to transmit and receive information to and from the manual cleaner; a second charger comprising a second charging terminal connected to a charging terminal of the robot cleaner, and a second transceiver configured to transmit and receive information to and from the robot cleaner; and a communication line configured to electrically connect the first transceiver and the second transceiver to each other.
