A hand vacuum cleaner has an air treatment member positioned in the air flow path downstream of a dirty air inlet. A motor and fan assembly produces an air flow through the air flow path. A handle is moveable between a first use position and a second use position.

A vacuum cleaner including a dirty air inlet, a fluid flow path extending from the dirty air inlet to a clean air outlet, a fluid flow motor positioned in the fluid flow path, and a filter assembly positioned in the fluid flow path. The filter assembly including a first cylindrical filter and a second cylindrical filter nested within and removable from the first cylindrical filter. An inner diameter of the first cylindrical filter is smaller than an outer diameter of the second cylindrical filter such that the second cylindrical filter is compressed in order to be nested within the first cylindrical filter.

A cleaner of the present disclosure comprises: a suction part; a main body comprising a body and a body cover for opening and closing the lower side of the body, the body comprising a cyclone part for separating dust from dust masses suctioned through the suction part and a dust container for storing the dust separated by the cyclone part; a handle part coupled to the main body; a filter part disposed inside the body, and filtering air, separated from the dust in the cyclone part; a movable part capable of moving inside the body along a space between the outside of the filter part and the inner circumferential surface of the body; an operation part disposed at the outside of the main body to move the movable part; and a delivery part penetrating through the main body, and connecting the movable part to the operation part.

A handheld vacuum cleaner includes a housing, motor, filter access door, filter, and dirt cup movably coupled to the housing. The housing defines a top, bottom, motor chamber, dirty air inlet, handle, clean air outlet, and air flow path. The air flow path is routed from the dirty air inlet to the clean air outlet. The motor is disposed in the motor chamber and defines a motor axis. The filter access defines a filter chamber with the housing. The filter is disposed in the filter chamber and defines a filter axis. The dirt cup defines a dirt cup axis extending parallel to the motor axis and filter axis. The filter access door is located below the filter axis. When the filter axis door is removed, the filter is removable in a downward direction from the filter chamber.

A surface cleaning apparatus having an air flow path; a suction motor positioned in the air flow path; an air treatment chamber provided in the air flow path; and a porous filter provided in the air treatment chamber and including an outlet passage from the air treatment chamber. An air impermeable impact wall in the air treatment chamber is opposed to an inlet into the air treatment chamber. At least a portion of the impact wall or a deflecting portion of a wall defining part of the front end of the air treatment chamber imparts a circular flow to air entering the air treatment chamber.

A hatch mechanism for a pre-separator 120, the mechanism comprising an aperture having a perimeter arranged in a plane, and at least three elongated obturator elements pivotably attached along the perimeter at respective hinge ends, each obturator element comprising a distal end arranged opposite to the hinge end along the extension direction of the obturator element, wherein adjacent obturator elements arranged along the perimeter are connected by foldable joining members arranged to guide the distal ends to a common intersection point distanced from the plane, whereby the obturator elements are arranged to fold about respective hinge ends to a position of mutual support to close the hatch mechanism.

A surface cleaning apparatus such as an extractor has a fluid flow path extending from a dirty fluid inlet head to a clean air outlet. The fluid flow path upstream of the separation stage comprises a removable portion.

A cleaner of the present disclosure comprises: a suction part; a main body comprising a body and a body cover for opening and closing the lower side of the body, the body comprising a cyclone part for separating dust from dust masses suctioned through the suction part and a dust container for storing the dust separated by the cyclone part; a handle part coupled to the main body; a filter part disposed inside the body, and filtering air, separated from the dust in the cyclone part; a movable part capable of moving inside the body along a space between the outside of the filter part and the inner circumferential surface of the body; an operation part disposed at the outside of the main body to move the movable part; and a delivery part penetrating through the main body, and connecting the movable part to the operation part.

A surface cleaning apparatus has a cyclone chamber provided in an air flow path. The cyclone chamber has a screen assembly with an outlet section, a longitudinally spaced apart distal section and a longitudinally extending porous section. The outlet section includes a non-porous member extending longitudinally inwardly an outlet section length from an outlet end of the outlet section to a longitudinally inwardly positioned inlet end of the outlet section. The outlet end of the outlet section overlies a cyclone air outlet. The porous section extends longitudinally inwardly from an outlet end of the porous section that is located at the inlet end of the outlet section. The distal section has a distal section length in the longitudinal direction that is greater than the cyclone outlet port length.

A cleaner includes: a main body that receives a suction motor; and a filter unit that is detachably coupled to the main body to filter air discharged from the suction motor and includes a ring-shaped filter and a filter frame that receives the ring-shaped filter, wherein the filter frame includes: an inner frame; an outer frame that defines a filter space for receiving the filter in cooperation with the inner frame; and a ring-shaped filter cover that connects the outer frame and the inner frame to each other and has one or more air openings.
