1. An arrangement comprising a particle outlet of a vacuum cleaner and/or of a cyclone separator, the particle outlet comprising a particle outlet opening, the arrangement further comprising a particle receiving device for receiving separated particles, the particle receiving device being attached to the particle outlet and comprising:
a particle receiving volume for receiving the particles,
an access element with an access element opening through which the particles can be transported into the particle receiving volume, and
a closure element,
wherein the access element is configured to be selectively displaced relative to the closure element into a closure position, in which the closure element closes the access element opening, or into an open position, in which the closure element releases the access element opening,
wherein the particle receiving volume is closed with respect to an environment in every possible position of the access element relative to the closure element.
