摘要： The invention relates to a method for optimizing a vacuum cleaning system comprising a substantially hoseless and tubeless vacuum cleaning device and a filter bag, where the substantially hoseless and tubeless vacuum cleaning device comprises a motor-fan unit having a characteristic motor-fan curve, a filter bag receptacle, a connection port for the filter bag and a cleaning head, and where the filter bag comprises filter material made of nonwoven material, comprising the step of: adapting the characteristic motor-fan curve and the size, the shape and the material of the filter bag and the size and the shape of the filter bag receptacle and the inner diameter of the connection port for the filter bag and the cleaning head to each other such that the vacuum cleaning system achieves an efficiency of at least 30%, preferably of at least 34%, particularly preferably of at least 38% when vacuuming according to the Standard on a Standard carpet type Wilton with an empty filter bag, where vacuuming according to the Standard is performed according to Standard EN 60312 and the Standard carpet type Wilton is provided according to Standard EN 60312. The Invention furthermore relates to a vacuum cleaning system having a substantially hoseless and tubeless vacuum cleaning device and a filter bag which is developed and/or manufactured using this method.

摘要： The invention relates to a vacuum cleaning apparatus comprising a vacuum cleaner and a filter bag. When using an empty filter bag, said vacuum cleaning apparatus has a quality factor QWun (defined as QWun=(hsaugun/hfbarun)×ψ where hsaugun is the vacuum, in [kPa], according to EN 60312, of the vacuum cleaning apparatus with an empty filter bag, hfbarun is the vacuum, in [kPa], in the filter bag-holding compartment with an empty filter bag, and ψ is the filtration efficiency, in [%], of the filter bag material) of more than 25, preferably more than 30, and/or when using a partly filled filter bag, the vacuum cleaning apparatus has a quality factor QWteil (defined as QWteil=(hsaugteil/hfbarteil)×ψ where hsaugteil is the vacuum, in [kPa], according to EN 60312, of the vacuum cleaning apparatus with a partly filled filter bag, hfbarteil is the vacuum, in [kPa], in the filter bag-holding compartment with a partly filled filter bag, and ψ is the filtration efficiency, in [%], of the filter bag material of more than 13, preferably more than 15, especially preferably more than 17.

摘要： The present invention relates to a vacuum cleaner filter bag for an upright vacuum cleaner. The vacuum cleaner filter bag according to the invention thereby has a greater length than width, one long side and one narrow side resulting. It is formed from two bag walls which are joined together circumferentially so that an internal space is configured between the two bag walls. One bag wall thereby has an inlet opening through which air to be cleaned can flow into the vacuum cleaner filter bag. The vacuum cleaner filter bag according to the invention is distinguished by the bag wall in which the inlet opening is introduced having folding which extends in the longitudinal direction of the vacuum cleaner filter bag, as a result of which this bag wall has increased flexibility and the vacuum cleaner filter bag opens during folding-over of the retaining plate when inserting the filter bag in a vacuum cleaner such that the air can enter essentially unimpeded into the filter bag.

摘要： A vacuum cleaner includes a suction head including a cover and a bottom plate provided with a suction hole through which air is sucked from a surface to be cleaned and rotatably combined with the cover. The bottom plate is rotated in one direction relative to the cover when the suction head moves forward, and is rotated in the other direction relative to the cover when the suction head moves backward. Further, the vacuum cleaner includes a brush base including brushes and movable upward and backward between the cover and the bottom plate. The brush base includes indicating parts exposed to the outside of the cover and forming at least a portion of the external appearance of the suction head.

摘要： Debris-collecting apparatus and methods of use are provided. One hood is provided for use with a mobile debris-collecting apparatus that has an input portion, a draft inducer, and a bag. The hood has an inlet for receiving air and debris drawn through the input portion by the draft inducer, and the hood includes a helical passage extending downwardly from the inlet at least two hundred and seventy degrees about an imaginary vertical axis to direct the air and debris from the inlet to the bag in a helical direction. An opening may be formed inside the helical passage, and the hood may include a filter removably positioned to restrict the debris from exiting through the opening. The filter may extend downwardly inside the helical passage and/or the bag, whereby further causing helical movement of the debris by providing an inner boundary around which the debris must pass.
