Abstract
A suction device for a cyclone filter of a hand-guided work apparatus includes 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. The housing has an inlet and an outlet for the second air stream, which has a simple configuration and a good suction performance for air laden with dirt particles. 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.
