A filter system for a vacuum cleaner is disclosed. The system comprises a housing reconfigurable relative to a bin between an operative configuration in which the housing is disposed upon the bin so that dirt separated from dirt-laden air can collect in the bin, and an idle configuration in which the housing is removed from the bin. The housing comprises an inlet for receiving dirt-laden air into the housing, an outlet via which cleaned air can exit the housing. The system further comprises first filtering means and second filtering means disposed within the housing, the first filtering means being positioned upstream of the second filtering means. The first and second filtering means comprises a filter medium configured to separate dirt from the dirt-laden air passing from the inlet to the outlet through the filter medium. The system further comprises filter cleaning means for removing dirt from the filter medium of the first filtering means when the housing is configured at least in the operative configuration.

A dust collector (1) is provided with a tank section (10) and a head section (20). The tank section (10) has a dust collection chamber (13) for containing dust. The head section (20) has a motor (23) and a dust collection fan (25). The dust collection chamber (13) has a cylindrical filter device (12) which, when air sucked in from the suction opening (11) flows through the filter device (12), separates dust from the air. A passage member (50) forms an air passage by which the outside air and a filter interior space (14) inside the filter device (12) are connected without having the filter device (12) therebetween. A cover body (60) closes the passage member (50) in an openable manner. The passage member (50) has first opening sections (53) facing the filter interior space (14) and located at different positions in the circumferential direction of the filter device (12).

A motor packing and mounting mechanism for a motor in a no larger than medium-sized appliance, such as wet and dry vacuum cleaner, a water aspirator, a water pump, or a humidifier, includes a motor seat supporting a motor in a housing so that the motor is axially disposed between the housing and the motor seat. At least one isolating cover is located inside the housing. A motor chamber for receiving the motor is defined among the housing, the motor seat, and the isolating cover. An axial mating clearance is defined between the isolating cover and the motor seat. A first seal is located and axially-mated in the axial mating clearance, the first seal having an elastic supporting portion. A cross section of the elastic supporting portion has a door-shaped structure, with the elastic supporting portion defining an opening facing an axial direction of the motor.

A wearable vacuum cleaner includes a harness configured to support the wearable vacuum cleaner on a user's back, a housing connected to the harness, a suction motor assembly disposed within the housing and operable to create a working airflow, and a collection bin configured to receive debris separated from the working airflow. The collection bin includes an opening adjacent a bottom portion of the collection bin and a lid moveably coupled to the collection bin to selectively cover the opening in a closed position and uncover the opening in an open position. The lid is movable to the open position to empty the contents of the collection bin through the opening while the collection bin remains attached to the housing.

A floor cleaning machine having a base, a suction foot, a dirty water tank in fluid communication with the suction foot, a suction turbine, and a separation container. The suction turbine is attached to the base and generates a suction air flow from the suction foot into the dirty water tank. The suction turbine has a housing with an inlet opening and an outlet opening through which air flows. The separation container adjoins the suction turbine housing and has an interior, which that communicates with the inlet opening and a bottom wall section that faces the interior. The bottom wall section is disposed vertically lower than the inlet opening. A drainage opening leads out of the bottom wall section into the environment and is provided with a valve that is closed during operation of the suction turbine is in operation and open when the suction turbine is not operated.

A device for introducing openings into a disposal bag for a vacuuming device, wherein the vacuuming device has a suction head and a collecting tank. The includes components that are configured in a manner corresponding to one another, wherein the components of the device that are configured in a manner corresponding to one another include an open structure, wherein the open structure is designed to effect pressure equalization between a first region and a second region of the collecting tank. Within the meaning of the invention, it is preferred for the proposed device to include a punch and a die, wherein the punch is arranged in the suction head and the die is arranged in the collecting tank. In a second aspect, the invention relates to a vacuuming device that includes at least one proposed device. In a further aspect, the invention relates to a method for introducing openings into a disposal bag for a vacuuming device.

A suction apparatus includes a suction apparatus housing, including a filter for cleaning a suction flow, wherein the suction apparatus housing has at least one filter fastening element for securing the filter to the suction apparatus housing, and including a filter cleaning device for mechanically cleaning the filter. The filter, the filter fastening element and the filter cleaning device are arranged within the suction apparatus housing. The filter cleaning device includes an actuation device and a hammer device. The actuation device and the hammer device interact such that the hammer device can be actuated by using the actuation device and, when actuated, the hammer device applies at least one pulse to the filter securing element.

A suction hose for a vacuum cleaner including a hose portion, which has a flexible dust removal hose body and a flexible jacket hose body, in which the dust removal hose body is arranged, wherein a suction flow channel for conducting a suction flow to the vacuum cleaner extends between longitudinal ends of the hose portion, which suction flow channel is bounded by a hose jacket of the dust removal hose body, a connection piece for connecting to the hand-held power tool or to the vacuum cleaner is arranged at at least one longitudinal end of the hose portion, and the jacket hose body and the dust removal hose body extend into an interior of a hose receptacle of the connection piece such that the dust removal hose body is sheathed by the jacket hose body into the hose receptacle.
