The invention describes a vortex finder for a cyclonic separator. The vortex finder includes a plurality of stationary vanes around which incoming air is guided into the vortex finder, in which a side of the vanes facing the incoming air is provided with a protrusion at a stagnation point. The protrusion is shaped so as to guide the incoming air into the vortex finder, and have a concave side following a shape of a neighboring vane, and a rounded top. Further, the protrusion has a height in a range between 70% and 130%, and in a range between 85% and 115% of a gap width between the vanes. The gap width between adjacent vanes increases from an outside to an inside of the vortex finder. A vacuum cleaner that includes a cyclonic separator has such a vortex finder.

A water reservoir for a drinks machine has a housing having a base and a side wall forming a water chamber. An outlet structure is formed on the base with an inner wall upstanding from the base, wherein an inner volume of the inner wall leads to an outlet of the water reservoir. An outer wall structure extends around the inner wall and a space between the inner wall and the outer wall structure forms a connection interface for connecting a water treatment unit. A lowest region of the inner wall defines the lowest liquid level in the reservoir. When the liquid is at the lowest liquid level, the water surface extends uninterrupted between the outside of the inner wall and the inside of the side wall.
