Claim:
A suction device for a cyclone filter of a hand-guided work apparatus, in particular a chain saw or angle grinder, comprising a blower which is located in a housing and a starting unit with a cable drum which is rotatably mounted about an axis, wherein ambient air sucked in with dirt particles is divided by the cyclone filter into a first air stream which is largely freed from dirt particles and into a second air stream loaded with dirt particles, wherein the housing has an inlet and an outlet for the second air stream, characterised in that the blower is mounted rotatably about an axis which is arranged coaxially to the cable drum axis and the housing is designed with a channel which is connected to the inlet and opens in the region of the cable drum axis, whereby the second air stream is effectively guided from the cyclone filter through the channel into the outlet, and characterised in that the channel runs radially to the cable drum axis.
