Abstract: A backpack sprayer has a carrying arrangement, on which a container for spraying agent is arranged. The container has a filling opening which can be closed by way of a lid. The carrying arrangement has a set-down position, in which the carrying arrangement is set down on a planar, horizontal set-down surface. The spraying agent region of the container is the region which is provided for spraying agent and extends as far as a maximum permissible filling height (max). The spraying agent region has a greatest horizontal inner cross-sectional area (A) in the set-down position. In order to allow simple filling of spraying agent and simple cleaning of the container, it is provided that the container can be opened at the filling opening over at least 60% of its greatest inner cross-sectional area (A).
