A power tool includes a power tool housing including a fluid inlet and a discharge outlet. A motor is supported by the power tool housing. A tool is configured to be moved relative to the housing by the motor. A fan is configured to be rotated by the motor, such that a fluid flow with debris generated by movement of the tool is drawn into the fluid inlet and through the discharge outlet. A filter is removably attached to the power tool housing. The filter includes a filter media configured to separate the debris from the flow of fluid. The filter media includes a collection container configured to store the debris. The filter also includes an opening in the filter media through which the flow of fluid with the debris enters the collection container, and a valve that is moveable between a closed position and an open position.

A docking station for a robotic vacuum cleaner has a pneumatic transfer mechanism that is used to direct air to the robotic vacuum cleaner to thereby transfer dirt from the robotic vacuum cleaner to a docking station.

A vacuum cleaner comprises a housing having a longitudinal axis. A motor-fan assembly is mounted in the housing and arranged to generate an airflow along an airflow path from a dirty air inlet to an air exhaust. A retractable nozzle defines the dirty air inlet and is moveably mounted on the housing. At least a portion of the retractable nozzle is arranged to move between a retracted configuration within the housing and a deployed configuration outside the housing. The portion of the retractable nozzle in the retracted configuration is aligned in a direction along the longitudinal axis and the portion of the retractable nozzle in the deployed configuration is aligned in a direction across the longitudinal axis.

A battery-operated backpack suction appliance, including a collection container, a technical unit connected to the collection container in an operating position of the suction appliance, and a backpack device connected to at least one of the collection container and the technical unit in the operating position for the suction appliance to be worn on the back of an operator, wherein the collection container is made of a foamed plastic material and wherein the collection container is configured to be removable from the technical unit in a toolless manner is disclosed.

An autonomous traveling floor cleaner is disclosed that improves cleaning efficiency. A floor cleaner may include a suction nozzle that suctions suction matter collected by a rotary brush, an extension nozzle that suctions suction matter collected by an extension brush, and a collection box for collecting, through an inlet, the suction matter suctioned by the nozzles. The floor cleaner may have an elongated profile. The extension nozzle may be switchable between a retracted posture and a lateral cleaning posture. The extension nozzle in the lateral cleaning posture may be pivotable rearward. The extension nozzle in the lateral cleaning posture may have a protruding end in the width direction to be aligned with an end of a turning range of the floor cleaner in the width direction.

The present invention relates to a vacuum cleaner filter bag composed primarily of plastic recyclates.

A suction device (10) with a suction device housing (20), in which a suction turbine (11) for generating a suction flow (S) is arranged, the suction turbine (11) having a suction turbine inflow opening (11A), through which the suction flow (S) can flow into the suction turbine (11) and at least one suction turbine outflow opening (11B), through which the suction flow (S) can flow out of the suction turbine (11), wherein the suction device housing (20) has a suction inlet (12) for letting in the suction flow (S) and a dust collecting chamber (21) for collecting dust contained in the suction flow (S), wherein a filter element (13) for retaining dust in the dust collecting chamber (21) is arranged between the dust collecting chamber (21) and a suction turbine inflow opening (11A) of the suction turbine (11), wherein the suction device (10) has a closure element (60) with a closure body (61) for closing the suction inlet (12), which closes the suction inlet (12) in a closure position (V) and is removed from the suction inlet (12) in a release position (FS). The suction device (10) has a supply receptacle (68) for receiving the closure body (61), when the closure body (61) reaches the release position (FS).

A method for operating a base station for a cleaning device is proposed, wherein exclusively by means of a pressure sensor and/or by means of a differential pressure the filling level of the container is determined as state of the base station and additionally at least one further state of the base station is determined and/or wherein on reaching a predefined filling level the maximum number of still possible extraction processes with-out emptying a container is limited.

A street sweeper comprises a dirt container and a suction device. The suction device comprises a suction mouth, a suction channel and a suction fan. The suction fan generates a suction flow which leads into the dirt container. Furthermore, the street sweeper comprises a recycling system with a separating device. The separating device separates sucked-in dirty water from the dirt container into the recycling system. Furthermore, the street sweeper comprises a fresh-water tank in which fresh-water is stored. Furthermore, a cleaning device is provided by means of which at least a part of the recycling system can be cleaned. The fresh-water from the fresh-water tank is used for cleaning the recycling system.
