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 dust collector with a dust collecting bag includes a housing defining a dust collecting chamber; a bracket in the dust collecting chamber; an operating member connectable with the bracket; the dust collecting bag being mounted to a supporting plate; and the bracket being rotatable around a rotating member from a first position to a second position. The housing further includes a connecting member, and the operating member includes a first state and a second state. When the operating member is in the first state, the bracket is located at the first position, and the supporting plate mounted on the bracket is connected with the connecting member. When the operating member is in the second state, the bracket drives the supporting plate to move towards the second position so that the supporting plate is separated from the connecting member, and the supporting plate is separated from the bracket.

The present invention relates to methods for the production of an improved integral connection of a retaining plate to the wall of a vacuum cleaner filter bag. According to a first variant, the retaining plate is not applied directly on the wall of the vacuum cleaner filter bag but rather a textile material is disposed between retaining plate and the wall. The connection of the retaining plate and the wall of the vacuum cleaner filter bag is thereby effected via the textile material. According to a second variant, in regions between retaining plate and wall of the vacuum cleaner filter bag, a film made of a thermoplastic material is disposed between wall of the vacuum cleaner filter bag and retaining plate. The connection of the retaining plate and the wall of the vacuum cleaner filter bag is thereby effected via the film. According to a third variant, the retaining plate is connected directly to the wall of the vacuum cleaner filter bag. The wall is thereby formed, at least in the region in which the retaining plate is applied, as film made of special thermoplastic materials. The present invention relates likewise to vacuum cleaner filter bags in which the retaining plate is connected integrally to the wall of the vacuum cleaner filter bag according to the preceding principles.

A vacuum cleaner dust container connector plate having a front surface having an opening for an airflow, a first side surface adapted to be inserted into holder of a vacuum cleaner, a second opposite side surface, the second side surface is arranged closer to the opening than the first side surface, a third side surface connecting the first and second side surfaces, and a forth side surface connecting the first and second side surfaces. The connector plate also comprises a flexible zone arranged between the opening and the first surface.

A docking station for a robotic cleaner may include a base having a support and a suction housing, a docking station suction inlet defined in the suction housing, wherein the docking station suction inlet is configured to fluidly couple to the robotic cleaner, and an alignment protrusion defined in the support. The alignment protrusion may be configured to urge the robotic cleaner towards an orientation in which the robotic cleaner fluidly couples to the docking station suction inlet.

The present disclosure provides, in one aspect, a debris collection device for an autonomous cleaning robot includes a cleaning pad portion configured to contact a floor surface. The cleaning pad portion includes a backing and at least one cleaning pad connected to a bottom surface of the backing. The autonomous cleaning robot includes a vacuum bag portion configured to collect at least a portion of debris removed from the floor surface by a vacuum assembly of the autonomous cleaning robot. A volume of the vacuum bag portion is positioned vertically above the cleaning pad portion.

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 vacuum cleaner includes a power head, a dirt collector, and an attachment plate. The power head includes an inlet, an outlet, and a suction source. The suction source is operable to draw air in through the inlet. The dirt collector includes a first wall that at least partially defines an internal volume. The first wall includes an opening that communicates between the internal volume and an external environment. The attachment plate removably couples the power head to the dirt collector. The attachment plate is coupled to the first wall of the dirt collector adjacent the opening and between the suction source and the dirt collector. The attachment plate includes an inlet opening and an outlet opening. The inlet opening and the outlet opening communicate between the internal volume and the external environment. The dirt collector is configured to be discarded.

The invention relates to a retainer plate for a vacuum cleaner filter bag, comprising a base plate in which a passage opening is formed, and a sealing element which is arranged at the edge of the passage opening, wherein the sealing element comprises at least one extruded film made of a thermoplastic elastomer, TPE.
