Portable vacuum cleaner comprising: • a housing, • a suction channel opening into a suction nozzle, • a suction material récipient, • a suction unit for generating a suction flow which provides a suction vacuum at the suction nozzle, • a separation chamber delimited by the housing and a cover element, which is arranged between the suction channel and the suction material container and comprises an inlet opening for a suction flow through the suction channel, an exhaust opening for an exhaust air flow and an outlet opening for suction material, and with • a separating unit which is arranged in the separating chamber and which is capable of separating the suction flow drawn in via the suction nozzle into an exhaust air flow flowing out of the suction apparatus and into suction material in the form of particles and fluid particles, wherein the suction material récipient is provided for collecting the separated particles and fluid components and the inlet to the suction material récipient or to an upstream suction material guideway constitutes the outlet opening of the separation chamber, characterized in that the separating unit comprises two stages of separation, namely a first stage, in which the separation takes place via a suction material guide element, and a second stage, in which the separation takes place via and a rotary separator, wherein • the suction material guide element is arranged in the direction of flow in continuation of the suction channel and is set up to separate suction material at least partially in a discharging manner, and • the rotary separator is arranged downstream of the suction channel in the direction of flow and aligned in the direction of the suction channel and is set up to separate particles and fluid constituents which are not discharged via the suction material guide element, and wherein • the suction material guide element comprises a ramp-shaped form and is embodied in such a way that it is able to divert liquid suction material in a direction deviating from the suction material flow by surface forces occurring between the liquid suction material and the suction material guideway. • a
