A bag-based filtering device for collecting debris from a cleaning robot via a debris evacuation station includes a filter bag configured to separate at least the portion of the evacuated debris from a flow of air generated by the evacuation station. The filtering device includes a conduit extending inward from an opening of the filter bag into the receptacle. The conduit is configured to pneumatically connect a receptacle of the filtering device with an inlet of the filtering device to direct the flow of air generated by the evacuation station through the filter bag to separate at least the portion of the evacuated debris from the flow of air.

A lid system for a wet-dry vacuum includes a lid shaped to cover an open end of a container and having a vacuum opening therethrough, and a hatch that engages the lid to cover and seal the vacuum opening when in a closed position and disengages from the lid in an open position to uncover the vacuum opening. A vacuum generator is mounted on the hatch, and a flanged filter is mounted on the lid and extends through the vacuum opening such that the flange supports the filter on the lid. When the hatch is in the closed position, the hatch compresses the flange against the lid to form an airtight seal between with the upper surface of the lid, and the vacuum generator communicates with the interior of the container. When the hatch is in the open position, the filter is insertable into and removable from the vacuum opening.

A closure device for closing a particle capture volume, in particular a bag or a container, including an access element with an access element opening for providing an access to the particle capture volume, a closure slide which can be selectively displaced relative to the access element into a release position or into a closure position. In the release position the closure slide releases the access element opening and in the closure position closes the access element opening, and a locking mechanism for locking the closure slide in the closure position with respect to the access element, where the locking mechanism 6 for unlocking requires a defined unlocking element which is separate from the locking mechanism.

A station for a cleaning device is provided. The station includes an accommodation chamber configured to be docked with the dust canister, a housing configured to have a dust bag disposed therein, a cover configured to open and close one region of the housing, a holder configured to be detachable to the dust bag and selectively communicate the dust bag with the accommodation chamber, and a lever configured to have one end disposed in one region of the housing and rotate in a first direction to selectively interfere with the cover. The lever rotates in a second direction opposite to the first direction to close the cover based on the dust bag being mounted on the holder and in communication with the accommodation chamber.

A vacuum cleaner dust container holder for holding a dust container having a connector plate. The holder has an insert slot configured to receive the connector plate of the dust container and configured to hold the connector plate in a working position within a vacuum cleaner during use of the vacuum cleaner. The insert slot is configured to bend at least a first portion of the connector plate upon insertion of the connector plate into the insert slot, or configured to bend at least a first portion of the connector plate after insertion of the connector plate into the insert slot. A connector plate for a vacuum cleaner dust container, and a vacuum cleaner comprising a holder are also provided

A dust collection box and a robot vacuum cleaner are disclosed. The dust collection box includes a box body, a first lid detachably arranged to the box body, a filter, and a filter missing-alert device arranged to the first lid. The filter missing-alert device includes a movable member. When the filter is not mounted into the box body and the first lid is arranged to be closed on to the box body, the movable member interferes with the box body, such that the box body cannot be closed with the first lid. When the filter is mounted into the box body and the first lid is arranged to the box body, the filter missing-alert device interferes with the filter to eliminate the interference between the movable member and the box body, such that the box body can be closed with the first lid.

Embodiments are directed to a vacuum cleaner and removably attachable filter. The filter is configured to separate debris from a flow of fluid drawn through the suction inlet. The filter includes a housing forming a first volume and a filter media forming a second inner volume. The filter media is coupled to the housing such that the first and second inner volumes together at least partially define a collection container configured to store debris separated by the filter media from the flow of fluid. The filter further includes an inlet opening that extends through the housing to provide fluid communication into the collection container such that the flow of fluid with the debris can flow into the collection container such that the flow of fluid with the debris can flow into the collection container and a relatively clean flow of fluid exits through the filter media.

A vacuum cleaner dust container having a dust bag, made of an air permeable material, and a connector plate, surrounding an opening in the dust bag. The connector plate is configured by the connector plate being slid into a holder of a vacuum cleaner to correctly position the opening therein. The connector plate has a central portion surrounding the opening, and an extending portion projecting from the central portion. The extending portion has a lower bending stiffness than the central portion about an axis perpendicular to the direction in which it is inserted. Thereby extending portion can be bent out of the plane of the central portion and into a curvature without bending the central portion, which facilitates fitting the connector plate in a vacuum cleaner canister with curved inner walls.

The invention relates to a holding plate for a vacuum cleaner filter bag having a bag wall, the holding plate including a base plate made of a first plastic material with a passage opening, and a connecting element that is connected to the base plate by a material bond and is made of a second plastic material, for connecting the base plate to the bag wall by a material bond, in particular by means of ultrasonic welding, characterized in that the connecting element is arranged on the side of the base plate that is to be connected to the bag wall.
