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 modular particle collection system includes a hollow lower member, a hollow upper member separably attached to the hollow lower member, a collection container separably attached to a longitudinal end of the hollow lower member opposite the hollow upper member, an inlet portion extending radially from the hollow lower member and configured to be fitted to a first portion of a vacuum system, a particulate filter, and an outlet portion extending radially outward from the hollow upper member and configured to be fitted to a second portion of vacuum system. Additional modular particle collection systems and a method of making a modular collection system are also disclosed.

A vacuum cleaner including: a suctioning unit; a main body including a cyclone part for separating dust from suctioned air and a dust container for storing the separated dust, and a body cover for opening and closing the lower side of the body; a filter unit, disposed in the body, for filtering air separated from the dust; an actuating unit capable of moving in the body between the outside of the filter unit and the inner circumference surface of the body; an operating unit disposed outside the body which operates in order to move the actuating unit; a transmission unit penetrating the body and connecting the actuating unit with the operating unit; and an elastic member disposed outside the body which elastically supports the operating unit.

A hand vacuum cleaner having a front end and a rear end positioned in a rearward direction rearward of the front end is described herein. The hand vacuum cleaner includes a dirty fluid inlet, an air treatment member downstream of the dirty fluid inlet, a pre-motor filter positioned in a pre-motor filter housing downstream from the air treatment member, a suction motor downstream of the pre-motor filter, an air flow path extending from the pre-motor filter to the suction motor, a clean air outlet downstream of the suction motor, and a handle. The pre-motor filter has a longitudinal length in the rearward direction that is longer than a transverse length in a direction transverse to the rearward direction. The pre-motor filter housing has first and second rearwardly extending pre-motor filter housing sidewalls and the pre-motor filter has first and second rearwardly extending pre-motor filter sidewalls that are positioned transversely inwardly of the pre-motor filter housing sidewalls. The pre-motor filter sidewalls are an upstream face of the pre-motor filter and the pre-motor filter has an inner cavity that is downstream of the upstream face.

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 hand vacuum cleaner has an air treatment stage positioned below an inlet conduit. A pistol grip handle is provided at the rear end of the hand vacuum cleaner. An arm member extends from the inlet conduit linearly rearwardly to the upper end of the pistol grip handle. A housing is provided at a lower end of the pistol grip handle. All operating components of the hand vacuum cleaner are located between a lower end of the housing and the inlet conduit.

A surface cleaning apparatus is described including a housing supporting a suction source, a dirt collection container, and a cyclonic separation device for separating dirt from the airflow passing through the apparatus. The apparatus further includes a ducting member having an inlet in communication with an outlet from the cyclonic separation device and an outlet in communication with a passage leading to the suction source. The ducting member is removably connected to the housing or the dirt collection container and is rotatably moveable between locked and unlocked positions, and rotational movement of the ducting member from its unlocked position to its locked position aligns the outlet of the ducting member with the passage leading to the suction source.

A docking station for a robotic surface cleaning apparatus has a momentum separator. The momentum separator has an upper wall, a lower wall and a first sidewall extending between the upper and lower walls. The first sidewall comprises a side screen and an end wall is spaced from and faces the side screen whereby an up flow chamber is positioned between the end wall and the side screen. The upper wall also comprises an upper screen and an upper end wall is spaced from and faces the upper screen wherein an upper air flow chamber is positioned between the upper end wall and the upper screen.

A handheld vacuum cleaner includes a frame, and a dust barrel and a locking portion mounted on the frame, wherein a front end of the dust barrel and the locking portion are movable relative to each other and are arranged opposite to each other; the dust barrel has a rotatable front cover at a front side thereof; and when the locking portion and the dust barrel move with respect to each other, the front cover is automatically rotatable to open, or close on the front side of the dust barrel due to limit by the locking portion.

The present disclosure relates to a cleaner system including: a cleaner; a cleaner station; and an imaginary plane including an imaginary suction flow path through line penetrating a suction flow path in a longitudinal direction and an imaginary suction motor axis defined by extending a rotation axis of a suction motor, in which when the cleaner is coupled to the cleaner station, the plane penetrates at least a part of the cleaner station, such that a center of gravity of the cleaner is disposed to pass through a space for maintaining balance of the station, and as a result, it is possible to stably support the cleaner and the station while preventing the cleaner and the station from falling down.
