A robotic dust collector includes: a cover plate that closes an opening of a housing; a first hinge member connected to the cover plate and having an insertion space; an elastic member disposed in the insertion space; and a second hinge member. The second hinge member includes a shaft part that is inserted in the insertion space and supports the elastic member. The second hinge member further includes a fixture part fixed to at least a part of the housing. The second hinge member supports the first hinge member in a manner that allows the first hinge member to rotate about a rotation axis.

A filtering device for an evacuation station includes a filter bag configured to collect debris evacuated from a cleaning robot by an evacuation station. The filtering device includes an interface assembly configured to interface with the evacuation station. The interface assembly includes (i) a base attached to the filter bag along an opening of the filter bag, (ii) an access door configured to provide or limit access to a space within the filter bag depending on whether the access door is in an open position or a closed position, and (iii) one or more hinges connecting the base to the access door. The access door is rotatable around the one or more hinges from the closed position to the open position.

A vacuum filter bag includes an inlet flange and gasket and a plug. The inlet flange includes axial ribs and recesses which improve the seal between the inlet gasket and a vacuum inlet port and prevent accidental removal of the filter bag from the vacuum inlet port. The plug more securely closes the filter inlet opening after use of the filter bag. The filter bag reduces user exposure to dust and debris captured with a vacuum and is particularly suited for minimizing exposure to hazardous materials.

The present invention relates to a retaining plate 1 for a vacuum cleaner filter bag, including a base plate 2 having a passage opening 3 formed therein and a closure device for closing the passage opening 3, where the closure device includes two closure parts 4, 5 arranged in a plane parallel to the passage opening 3, and where the closure parts 4, 5 are movable relative to each other in the plane, so that, by a closing movement in the plane, they are movable to a closure position at which they close the passage opening 3 by overlapping each a respective part of the passage opening 3.

The invention comprises a vacuum cleaner filter bag comprising a base element, a cover element having an inflow opening and a retaining plate surrounding the inflow opening at least in part is connected to the cover element, and at least four intermediate elements which are arranged between the base element and the cover element and each comprise a passage opening aligned with the inflow opening of the cover element, where the intermediate elements are configured as filter elements and each comprise nonwoven fabric and/or fibrous nonwoven, where the intermediate element directly adjoining the base element is connected to the base element along the outer edge of the intermediate element or along the edge of the passage opening, and where adjacent intermediate elements are connected to each other alternately along the edge of the passage openings and along their outer edge.

A dust collecting device includes a bin, a dust bag assembly, a bin cover, a trigger structure, a detector and a controller. The trigger structure moves between an initial position in which the trigger structure does not trigger the detector and a trigger position in which the trigger structure triggers the detector. When the dust bag assembly is installed in the bin and the bin cover covers the bin, the dust bag assembly and the bin cover respectively pushes the trigger structure, such that the trigger structure moves from the initial position to the trigger position and triggers the detector. The controller is electrically connected with the detector. The controller restricts an operation of the dust collecting device according to an untriggered state of the detector, and releases the operation of the dust collecting device according to a triggered state of the detector.

A vacuum cleaner includes a motor housing, a motor and fan assembly in communication with the motor housing, a housing forming a receptacle in fluid communication with the motor housing, and a filter assembly removably insertable into the receptacle. The filter assembly includes a filter supporting a filter. The filter assembly further includes a seal and a lock member movable relative to the tray between a locked position and an unlocked position. Movement of the lock member to the locked position engages the seal with the housing when the filter assembly is inserted in the receptacle.

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 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 stick vacuum cleaner comprising an elongated shaft part, a housing arranged to be attached to the elongated shaft part, the housing comprising an air inlet, a container arranged to accommodate a removable air-permeable dust bag, a motor fan unit for creating an airflow, and an exhaust air outlet, a nozzle arranged at a first end of the elongated shaft part, the nozzle comprising a nozzle inlet via which debris is transported from a surface to be cleaned by means of the created airflow to the dust container, and a handle arranged at a second end of the elongated shaft part, wherein the container is arranged to be removably attached to the housing.
