  • the Staubabscheidevoriques is formed in hand-held vacuum cleaners usually as bagless Staubabscheidevortechnisch in which the incoming air is rotated to separate dust and dirt on the principle of centrifugal separator.
  • the Staubabscheidevoriques is designed as a bottom-side closed Staubabscheidevoriques, wherein the dirt accumulates in the bottom area.

  • Another advantage of the at least partially sloping bottom surface is that a wedge-shaped dust collection volume is formed. If coarse dirt such as larger particles or leaves are conveyed by the rotating air in this wedge-shaped area, these coarser dirt particles are clamped there and thus removed from the rotating air flow. Due to the wedge shape so the deposition of coarse dirt is improved.
  • Another advantage is that when sucking in working position with the nozzle on the ground by the slope of the bottom surface is prevented that the deposited dirt slips forward to the front wall of Staubabscheidevoriques. Rather, the deposited dirt is retained by the slope and collects at the beginning of the slope. This is advantageous because the dirt thus accumulates in areas of the Staubabscheidevortechnisch in which the flow rates are relatively low. For example, less dirt gets into a subsequently arranged filter, which reduces maintenance and improves performance. Even when sucking overhead, the dirt slips more easily into the area of the Staubabscheidevortechnisch, in which the flow rate is relatively low.

  • the angle 33 between the axis of rotation 13 and the vertical 32 corresponds to the angle 20, by which the chamfered portion 16 of the bottom surface is inclined relative to the transverse plane 18.
  • the bevel of the base surface thus leads to a corresponding tilting of the axes of the individual components to the front, so that a total of a novel lines of the vacuum cleaner 1 results.
  • the dust-collecting device 4 acts optically smaller than it actually is by the tilting. Due to the chamfering of the standing surface, the rotational axis 34 of the motor-blower unit 5 is also tilted forward by a certain angle.
  • the beveled footprint leads to an increase in the position of the receptacle 10 and the replaceable battery 9 inserted in the receptacle 10.
  • the replaceable battery 9 can be removed from the receptacle 10 without the use of tools and into the receptacle 10 are used.
  • the direction in which the battery 9 is inserted into the receptacle 10 preferably in the range of 10 ° to 30 ° relative to the horizontal base 31.
