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 hand-held suction system includes: a hand-held suction device, a tube unit and a bag unit, wherein the tube unit has a suction tube and a tube connecting part, and wherein the bag unit has a collecting bag and a bag connecting part. The tube connecting part and the bag connecting part are designed to form a mechanical connection to one another in order to hold the bag unit by way of the tube unit. The tube connecting part is arranged in such a way on a circumference of the suction tube, in an upper half of the circumference in a circumferential direction, in a correct operating position of the suction system, and the suction system is designed in such a way that the bag unit held by the tube unit extends downwards in the circumferential direction along the suction tube, on the upper half of the circumference.

A housing for a work implement has a first housing shell with first outer wall and a second housing shell with second outer wall. The first and second outer walls contact each other along a separation plane. The first housing shell has a first rib extending transversely to the separation plane and projecting past the separation plane into the second housing shell. First measuring points are located in the separation plane. The first rib has a first rib height measured in transverse direction from a first measuring point to a first end of the first rib facing the second housing shell. The second housing shell has a second shell height measured in transverse direction from the same first measuring point to an inner side of the second housing shell. The first measuring points include measuring points where the first rib height is at least 15% of the second shell height.

Housing

The disclosure relates to a handheld work apparatus, wherein the work apparatus includes a housing, a drive motor for driving a tool, and a handle disposed on the housing. A contour is provided on the handle and a counter contour is provided on the housing. In the inoperative position of the handle, a minimum friction torque (M) which acts about the pivot axis is provided between the handle and the housing. In the operative position of the handle, the contour and the counter contour are operatively connected in such a manner that a further friction torque (M) which acts about the pivot axis is present between the handle and the housing. The further friction torque (M) in the operative position is greater than the minimum friction torque (M) in the inoperative position.

Handheld work apparatus

A green area maintenance system includes an autonomous mobile green area maintenance robot having a treatment tool and a cutting tool differing from the treatment tool. The robot and the cutting tool are configured to allow fixing of the cutting tool to the robot. The system includes a user control device, and has an autonomous operation mode and a cutting operation mode. In the autonomous operation mode the autonomous mobile green area maintenance robot with its treatment tool operates autonomously and the cutting tool is set out of operation, and in the cutting operation mode the cutting tool is fixed to the green area maintenance robot and operable. The robot with its treatment tool and cutting tool are controlled by a user via the user control device, and an operation mode switching device for switching between the autonomous operation mode and the cutting operation mode.
