A hand vacuum includes a nozzle portion at a front end of the hand vacuum having a dirty air inlet. An air flow passage extends from the dirty air inlet to a clean air outlet in a main body rearward of the nozzle portion. The main body houses a suction motor in the air flow passage. First and second laterally spaced apart opposed arm members extend between the nozzle portion and the main body, and a volume is positioned between the nozzle portion, the main body and the opposed arm members. An air treatment member assembly comprising an air treatment member is removably positionable in the volume. A pistol grip handle assembly is provided on a lower portion of the main body. The handle assembly is positioned rearward of the volume and the air treatment member assembly is removable downwardly.

A hand vacuum cleaner comprises a cyclone having a dirt outlet in communication with a dirt chamber. The cyclone has a central longitudinally extending axis, wherein, when the upper end of the hand vacuum cleaner is positioned above the lower end of the hand vacuum cleaner, the central longitudinally extending axis is oriented generally horizontally and the dirt outlet comprises a slot provided in an upper portion of the sidewall of the cyclone

A robot cleaner comprising: a cleaner body including a controller, the cleaner body having a dust container accommodation part formed therein; a wheel unit mounted in the cleaner body, the wheel unit of which driving is controlled by the controller; and a dust container detachably coupled to the dust container accommodation part, wherein a first opening and a second opening are disposed at the same height in an inner wall of the dust container accommodation part, wherein the dust container includes: an entrance and an exit, disposed side by side along the circumference of the dust container, the entrance and the exit, respectively communicating with the first opening and the second opening when the dust container is accommodated in the dust container accommodation part; and a flow separating part extending downwardly inclined along the inner circumference of the dust container.

A cyclone unit capable of enhancing dust collection performance. A cyclone unit includes a cyclone unit body, a dust box and a core tube. The cyclone unit body includes a lower base, an upper base and a middle base sandwiched between the lower base and the upper base. The dust box is assembled to the cyclone unit body so as to collect dust and dirt. The core tube, having a meshed shape, is assembled to the middle base so as to be located inside the dust box. The core tube is detachable from the middle base while the upper base is assembled to the lower base.

A vacuum cleaner comprising a suction source operable to generate an airflow, a first stage cyclonic separator configured to separate debris from the airflow, the airflow rotatable about a first stage separator axis in the first stage separator to separate the debris from the airflow, a second stage cyclonic separator downstream from the first stage cyclonic separator, the second stage cyclonic separator configured to separate debris from the airflow, a first stage collector configured to receive debris from the first stage cyclonic separator, and a second stage collector configured to receive debris from the second stage cyclonic separator, the second stage collector being within the first stage collector, the second stage collector having a cross section taken normal to the first stage separator axis that is polygonal.

A vacuum cleaner includes a suctioning unit, a main body including a cyclone unit for separating dust from the air suctioned through the suctioning unit, a body forming a dust container for storing the dust separated by the cyclone unit, and a body cover for opening and closing the lower side of the body. A filter unit is arranged in the body for filtering air. An actuating unit is configured to move in the body along a space between the outside of the filter unit and the inner circumferential surface of the body.

A surface cleaning apparatus has a cyclone bin assembly having a cyclone chamber. The cyclone chamber with a physical filtration member defining the cyclone air outlet. The physical filtration member extends from the cyclone air inlet end of the cyclone chamber towards an openable bottom end of the cyclone chamber. The physical filtration member comprises a conical section which decreases in diameter towards the openable bottom end of the cyclone chamber, wherein a projection of the conical section meets at a location that is positioned between the physical filtration member and the openable opposed end. An openable bottom end of the cyclone bin assembly and the openable bottom end of the cyclone chamber are openable concurrently.

A separating device that is connectable to a vacuuming device for separating dirt particles from an air stream drawn in by the vacuuming device, containing at least one separator. The at least one separator contains an inlet opening for the air stream and a first and second outlet opening, wherein the first outlet opening serves for the exit of drawn-in dirt particles from the separator and the second outlet opening serves for the exit of the drawn-in air stream and of the drawn-in dirt particles from the separator, and wherein a first and second collection vessel for collecting the dirt particles separated from the separator is contained, and wherein the first collection vessel is positioned in a direction beneath the first outlet opening and the second collection vessel is positioned in a direction beneath the second outlet opening.
