The invention comprises a retaining plate (1), comprising a first plate (2) and a second plate (3) arranged in a first plane, and a third plate (8) arranged in a second plane which runs in parallel to the first plane, the third plate (8) having a lower flexural stiffness than the first plate (2) and the second plate (3), wherein the first plate (2) and the second plate (3) are interconnected by means of the third plate (8) such that a hinge is formed between the first plate (2) and the second plate (3) about the hinge axis (A) of which the first plate (2) and/or the second plate (3) can be bent together with the respective part of the third plate (8) connected thereto.

Described herein is a vacuum device. In various embodiments, the vacuum device includes a vacuum housing; a motor housing coupled to the vacuum housing; a motor disposed in the motor housing and configured to apply suction toward the vacuum housing; an inlet nozzle releasably coupled to a side of the vacuum housing and configured to receive a waste material; and a disposable vacuum bag disposed in the vacuum housing and configured to receive the waste material that passes through the inlet nozzle.

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 invention comprises a vacuum-cleaner filter bag (1) having a bag wall (2) and a retaining plate (3), the retaining plate (3) the retaining plate (3) comprising an least partially cylindrical connection piece (4) extending in the direction of the through opening (5) formed in the retaining plate (3), the bag wall (2) being connected to the lateral surface of the connection piece (4) along the periphery of the connection piece.

The invention comprises a vacuum cleaner filter bag (1), comprising a bag wall (2) and a retaining plate (3), wherein the retaining plate (3) is connected to an at least partially cylindrical connection piece (4) which extends in a direction perpendicular to a passage opening (5) formed in the retaining plate (3), wherein the bag wall (2) is connected with the lateral surface of the connection piece (4) along the circumference thereof.

A robotic cleaning system may include a robotic cleaner having a robotic cleaner dust cup and a docking station having a docking station dust cup configured to fluidly couple to the robotic cleaner dust cup. The docking station dust cup may include a first debris collection chamber, a second debris collection chamber fluidly coupled to the first debris collection chamber, and a filter fluidly coupled to the first debris collection chamber and the second debris collection chamber.

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 robotic cleaning system may include a robotic cleaner having a robotic cleaner dust cup and a docking station having a docking station dust cup configured to fluidly couple to the robotic cleaner dust cup. The docking station dust cup may include a first debris collection chamber, a second debris collection chamber fluidly coupled to the first debris collection chamber, and a filter fluidly coupled to the first debris collection chamber and the second debris collection chamber.

A station suctioning dust from the robot cleaner includes a docking suction port connectable to a robot cleaner, a dust container to store dust from the robot cleaner, a duct connected to the docking suction port and the dust container, a holder disposed in the dust container, and to which a dust bag is mountable, and a lever configured to hinder a connection of the holder and the duct while the dust bag is in a separated state from the holder, and the lever allows the connection of the holder and the duct while the dust bag is in a mounted state to the holder.

A docking station for a robotic cleaner may include a base, a docking station dust cup removably coupled to the base, a latch actuatable between a retaining position and a release position, and a release system configured to actuate the latch between the retaining and release positions. The docking station dust cup may be removable from the base in response to a pivotal movement of the docking station dust cup relative to the base about a pivot point. The latch may be horizontally spaced apart from the pivot point, wherein, when the latch is in the retaining position, pivotal movement of the docking station dust cup is substantially prevented.
