A hand-held treatment system includes: a hand-held treatment device and at least one attachment, wherein the treatment device has a movable treatment part and an electric drive motor system for moving the treatment part. The electric drive motor system has at least one electrical path with at least one interruption. The at least one attachment has a contact bridge. The treatment device and the at least one attachment are configured for the spatial arrangement of the at least one attachment from a hazard position into a safety position, which is different from the hazard position, on the treatment device such that by the at least one attachment being in the hazard position, the at least one contact bridge does not electrically bridge the at least one interruption, and by the arrangement of the at least one attachment in the safety position, the at least one contact bridge electrically bridges the at least one interruption.

A blower apparatus is driven by a drive motor and has an intake opening and a discharge opening. The blower apparatus has a handle for guiding the blower apparatus with the handle being mounted on the blower apparatus such that it is pivotable from a first position into at least a second position. The blower apparatus is configured such that, during operation of the blower apparatus, an air flow passes through the discharge opening in a discharge direction. The handle has a grip region, which, in the first position, is inclined differently with respect to the discharge direction compared with the second position.

A vacuum device has a motor-driven blower wheel with suction side and with pressure side with pressure channel and blow-out opening. An intake pipe at the suction side has an intake opening and a discharge opening at opposed ends. The intake pipe conveys a suction airflow entraining first and second collected materials. Through the discharge opening the first collected material is discharged from the intake pipe. A blower inlet opening is formed in a wall of the intake pipe. Blower inlet opening, blower wheel, and pressure channel are configured such that second collected material passes through blower inlet opening and blower wheel into the pressure channel for discharge through blow-out opening. The blower inlet opening, in longitudinal direction of the intake pipe, is positioned between discharge opening and intake opening at a first spacing to the intake opening and at a second spacing to the discharge opening.
