A vacuum cleaner is described herein that uses an elongated design that provides the various vacuum components along nearly an entire length of the vacuum cleaner and in-line with one another. According to some embodiments, at least one waste receptacle, a filter structure, and a motor are each axially aligned with a longitudinal central axis of a body of the vacuum cleaner. An air suction inlet may also be arranged at a distal end of the body and axially aligned with the longitudinal central axis. In some examples, the body maintains a substantially constant diameter along its entire length.

A vacuum cleaner includes a housing defining a longitudinal axis, an inlet defining an opening through which debris is provided into the housing, a cyclone chamber configured to receive the debris from the inlet, the cyclone chamber being annular, defining a central opening and a debris opening positioned radially outward of the central opening. The vacuum cleaner includes a dust collection chamber configured to receive the debris from the cyclone chamber via the debris opening, a suction motor assembly positioned within the housing and configured to generate an airflow through the inlet and the cyclone chamber, and an airflow passage extending from the central opening of the cyclone chamber to the suction motor assembly. The suction motor assembly draws the airflow from the cyclone chamber through the airflow passage. The airflow passage extends downward from the cyclone chamber and into an interior of the dust collection chamber.

A surface cleaning apparatus has an air flow path extending from a dirty fluid inlet to a clean air outlet with an air treatment chamber and a suction motor positioned in the air flow path. A plurality of ribs are provided on an interior surface of the air treatment chamber. The surface cleaner is operable in a bag mode of operation in which a bag is positioned in the air treatment chamber and a vacuum airflow path provides vacuum to assist in retaining the bag in position, and the surface cleaner is operable in a bagless mode of operation

A portable surface cleaner having a front end, a rear end and side walls extending between the front and rear ends, each of the front and rear ends has an end wall, wherein a longitudinal axis extends in a longitudinal direction centrally through the portable surface cleaner and intersects the end walls. The surface cleaner has an air flow path extending from a dirty fluid inlet to a clean air outlet with an air treatment chamber and a suction motor positioned in the air flow path. The suction motor is spaced from the air treatment chamber in the longitudinal direction. In operation to clean a surface, a brush and a hose are fluidically connected to the dirty air inlet.

The present disclosure includes a separating device in which trash, garbage, and air flow through a suction port. A vacuum suction device is provided at the outlet side of the separating device and generates a suction force so that trash, garbage, and air can be sucked through the suction port. Additionally, a passage portion connects the separating device and the vacuum suction device to each other. Further, a collection container is provided on the lower portion of the separating device, and a collection bag accommodates the trash. A bag fixing means is provided to fix the upper end of the collection bag, and a suction passage in communication with the inner upper portion of the collection container and the inner lower portion of the passage portion sucks in the air included in a flow space between the collection bag and the collection container.

A dust collector of a vacuum cleaner including a dust collection case including an outlet; a cyclone module arrangeable in the dust collection case and inducing a swirling airflow of air; and a discharge door movable between an open position to open the outlet and a blocking position to close the outlet. The cyclone module including a fixed unit to be fixed to the dust collection case, a rotation unit having a rotation state of being rotatable with respect to the fixed unit based on the discharge door being in the open position and a locking state of being restricted from rotation with respect to the fixed unit based on the discharge door being in the blocking position, and a foreign substance blocking structure configured to block the foreign substance from being introduced into a gap along a vertical direction between the fixed unit and the rotation unit.

A hand vacuum cleaner has a hand vacuum cleaner axis that extends centrally from a front end of the hand vacuum cleaner rearwardly to a rear end of the hand vacuum cleaner. The hand vacuum cleaner has a cyclone assembly including a cyclone chamber and a dirt collection chamber. A line that extends in a common horizontal direction with the hand vacuum cleaner axis extends through the cyclone chamber and the dirt collection chamber.

A separation system for a vacuum cleaner is provided and includes a bin defining a chamber having an airflow inlet, and a filter for filtering airflow from the airflow inlet. The filter is disposed within the chamber. The separation system further includes a wiping mechanism to wipe both a wall of the chamber and the filter in response to a single actuation of the wiping mechanism.

A docking station has an openable dirt collection region which, during an evacuation operation of the docking station, receives dirt that is transferred from a surface cleaning apparatus; and a lock having a locked position in which the dirt collection region is secured in a closed position, and an unlocked position in which the dirt collection region is openable. During the evacuation operation, the lock is inhibited from moving to the unlocked position.

A docking station for a surface cleaning apparatus comprises a docking station air inlet that is connectable in fluid flow communication with the dirt collection region of the surface cleaning apparatus. An air flow path extends from the docking station air inlet to a docking station air outlet. A first cyclonic stage comprises a cyclone chamber and a docking station dirt collection region. The cyclone chamber has a cyclone chamber air inlet, a cyclone chamber air outlet and a cyclone axis of rotation, wherein, when the docking station is placed on a horizontal surface and is in operation, the cyclone axis of rotation extends generally vertically. The first cyclonic stage comprises a first stage air treatment chamber of the docking station.
