    Bewegen, mittels eines Antriebsmotors (430), des beweglichen Presselements (310) zu einer ersten Fläche eines stationären Elements (320), das in der Staubsammeleinheit (200) befestigt ist,
    Bestimmen, ob ein auf das bewegliche Presselement (310) ausgeübter Widerstand gleich oder größer als ein Bezugswert ist,
    wobei, wenn der Widerstand gleich oder größer als der Bezugswert ist, das bewegliche Presselement (310) für eine vorbestimmte Zeit gestoppt wird, und das bewegliche Presselement (310) dann mittels des Antriebsmotors (430) in einer entgegengesetzten Richtung bewegt wird, und
    wobei der Prozess des Komprimierens des Staubs während des Betriebs des Staubsaugers wiederholt wird.
  2. Das Verfahren gemäß Anspruch 1, wobei das Komprimieren des Staubs ferner ein Bewegen des beweglichen Presselements (310), das zu der ersten Fläche bewegt wird, zu einer zweiten Fläche des stationären Elements (320) aufweist.
  3. Das Verfahren gemäß Anspruch 1 oder 2, wobei das Komprimieren des Staubs ein Bestimmen aufweist, ob ein Bewegungsbereich des beweglichen Presselements (310) gleich oder geringer als ein Bezugswert ist.
  4. Das Verfahren gemäß Anspruch 3, ferner mit einem Informieren eines Anwenders über die Tatsache, dass der Bewegungsbereich kleiner als der Bezugswert ist.
  5. Das Verfahren gemäß einem der Ansprüche 1 bis 4, ferner mit einem Stoppen des beweglichen Presselements (310), nachdem das bewegliche Presselement (310) zu einer Seite des stationären Elements (320) bewegt wurde, welches in der Staubsammeleinheit befestigt ist, nachdem der Saugmotor seinen Betrieb stoppt.
  6. Das Verfahren gemäß Anspruch 5, wobei das bewegliche Presselement ein Drehelement (310) ist und in der Staubsammeleinheit (200) rotiert.
  7. Das Verfahren gemäß Anspruch 6, wobei das Drehelement (310) sich zu der ersten Fläche des stationären Elements (320) bewegt, wenn der Saugmotor seinen Betrieb stoppt.
  8. Das Verfahren gemäß Anspruch 7, wobei die erste Fläche des stationären Elements (320) einer Drehrichtung des Drehelements (310) zugewandt ist.
  9. Das Verfahren gemäß Anspruch 8, wobei, nachdem das Drehelement (310) sich zu der ersten Fläche des stationären Elements (320) bewegt, das Drehelement (310) sich zu einer zweiten Fläche des stationären Elements (320) bewegt und stoppt.
  10. Das Verfahren gemäß Anspruch 6, ferner mit einem zusätzlichen Drehelement, wobei, wenn der Saugmotor seinen Betrieb stoppt, eines der Drehelemente stoppt, nachdem es sich zu einer ersten Fläche des stationären Elements (320) bewegt, und das andere der Drehelemente stoppt, nachdem es sich zu einer zweiten Fläche des stationären Elements (320) bewegt.
  11. Das Verfahren gemäß Anspruch 10, wobei, während des Betriebs des Saugmotors, der in der Staubsammeleinheit gespeicherte Staub durch die Presselemente komprimiert wird.
