Abstract: A filter arrangement for a vacuum cleaning appliance includes: a filter enclosure having an enclosure opening; a filter configured to be received through the enclosure opening into the filter enclosure in an insertion direction; and retention means operable between latched and unlatched states for releasably retaining the filter in the filter enclosure. The filter includes an actuation portion configured to operate the retention means, wherein the actuation portion is moveable between at least first and second positions and is biased towards the second position. When the filter is in the filter enclosure, movement of the actuation portion in the insertion direction from the first position to a depressed position transitions the retention means to the unlatched state, whereinafter the actuation portion is moved to the second position in which at least a part of the actuation portion is elevated above the enclosure opening.

Abstract: A filter assembly includes a filter housing, a first filter, and a second filter, wherein the first filter is a pre-motor filter, and the second filter is a post-motor filter, and both the first and second filters are fixed to the filter housing and are annular about a common axis.

Abstract: A cleaning appliance includes a dirt separator for separating dirt from an airflow, and a main body, the dirt separator including a bin for collecting dirt separated from the airflow, and the main body including a runner portion extending alongside a side wall of the bin, wherein the bin is slidable along the runner portion between an operational position and an extended position, and a release catch releasably engages with a formation on the runner portion to prevent the bin from being separated from the cleaning appliance, and wherein the release catch is positioned on the side wall of the bin such that it is hidden by the runner portion of the main body unless the bin is in the extended position.

Abstract: A cyclonic separator comprising a cyclone chamber defined between an outer wall and a shroud. The shroud comprises an inlet opening through which fluid enters the cyclone chamber, and a plurality of perforations through which fluid exits the cyclone chamber. Fluid within the cyclone chamber is then free to spiral about the shroud and over the inlet opening.

Abstract: A dirt separator that includes an inlet; an outer wall defining a first dirt collection chamber of a first separation stage; an inner wall defining a second dirt collection chamber of a second separation stage; at least one rib extending from the inner wall into the second collection chamber; and a closure member hingedly connected to the dirt separator and movable between a closed position for sealing open ends of both the first and second dirt collection chambers and an open position for escape of dirt from the open ends. The closure member comprises a seal for sealing against the inner wall when the closure member is in the closed position, and the at least one rib has an end edge that is inclined such that the seal rides along the end edge and onto the inner wall as the closure member is closed.

Abstract: A cleaning appliance includes a dirt separator for separating dirt from an airflow, the dirt separator including a bin for collecting dirt separated from the airflow, the bin including a bin lid having a closed configuration in which the dirt is retained in the bin, and an open configuration for the removal of dirt from the bin. The cleaning appliance further including an inlet, the inlet extending through an opening in the bin lid, and the inlet including an attachment interface. The cleaning appliance further includes an interlock mechanism to prevent the bin lid from being opened when an attachment is connected to the attachment interface.
