Abstract: A robotic vacuum cleaner for autonomously cleaning surfaces. The robotic vacuum cleaner comprises an appliance housing and a side arm. The side arm is movably mounted on the appliance housing. A brush element is disposed on the side arm. The side arm projects, in a first position, in front of the appliance housing in part and, in a second position, is received by the appliance housing. The side arm comprising a first arm element having a first end and a second end. The first arm element is movably mounted in the appliance housing at the first end. The side arm comprises a second arm element having a first end and a second end. The second arm element is movably mounted in the appliance housing at the first end and is movably connected to the second end of the first arm element at the second end.

Abstract: A floor-type vacuum cleaner includes a housing and rollers attached to the housing that are configured to provide movement of the housing. Each roller is disposed on a roller axle so as to be rotatable. At least one of the rollers includes a rigid hub and an air-filled, rubber, resilient, damping tire. Alternatively, at least one of the rollers has a damping property and includes alternating concentric layers of rigid and flexible components, with air being disposed between at least one of the rigid components and at least one of the flexible components.

Abstract: A vacuum cleaner includes a housing, a motor-driven suction fan disposed in the housing, a fan motor and a power supply device configured to provide power supply to the fan motor. The vacuum cleaner also includes both a rechargeable battery and cord reel permanently integrated in the housing such that the vacuum cleaner is configured to be alternately operable in a battery mode and a mains mode.

Abstract: A vacuum cleaner includes a housing having at least one holding device configured to receive a vacuuming tool in a parked position and at least one illumination device associated with the holding device.

Abstract: A canister vacuum cleaner includes a housing, a suction hose connectable to the housing, a vacuum attachment, and a suction wand. The suction wand includes at least an upper wand section and a lower wand section that can be separated from one another, an upper end of the upper wand section being couplable with the suction hose, a lower end of a lower wand section being couplable with the vacuum attachment, at least one of the lower wand section and the vacuum attachment being configured to be held to the housing in a parked position by a first connector, a second connector being disposed on the upper wand section and attachable to the lower wand section.

Abstract: A vacuum cleaner for use with a dust bag provided with a flange adapted to be slidably received in a bracket pivotally mounted in a dust collection chamber between a first position in engagement with a suction opening of the dust collection chamber and a second position removed from the first position. The dust collection chamber is provided with a lid selectively pivotable between open and closed positions. Movement of the lid to its closed position is contingent upon the flange of a dust bag having been inserted into the bracket to release the bracket from a blocking mechanism effective in the second position of the bracket and constituted by an upper edge of the bracket and a groove in the lid.

Abstract: A round wire is cold formed in a first pair of forming rolls to produce a flat metal ribbon cable having a specified width, followed by cold forming the flat metal ribbon cable in a second pair of forming rolls to produce a flat metal ribbon cable having a specified thickness and said specified width without any additional edge processing.

Abstract: The invention relates to a method for producing flat metal ribbon cables by cold-rolling, which is characterized by rolling, in a first pass, a round wire (2) on a two-stand metal forming device (4) between immediately successive pairs of rolls (8,9;16,17) with identical rotational axes to a defined breadth and, in a second pass, to a defined thickness without further edge machining.

Abstract: A vacuum cleaner includes a handle and a bottom part, the handle being swivel-mounted to the bottom part via an articulated joint. The bottom part includes at least one bottom-side suction opening, a dust chamber bounded by dust chamber walls, a fan unit, and an additional suction opening for a suction hose. A first flow path through the bottom-side suction opening and a separate parallel flow path through the additional suction opening are guided into the dust chamber via a common inlet opening formed in one of the dust chamber walls. The two flow paths are arranged in the bottom part and are guided into the inlet opening together approximately parallel to each other by a flow-guide element located between the two flow paths.

Abstract: A rolling apparatus is proposed with four rolls arranged in the shape of a star whereby one drive unit each is assigned to the rolls and whereby an adjusting unit each precedes the rolls through which the rolls are arranged adjustably in a radial and an axial direction. The separate and comprehensive triggering of the individual rolls (3) always allows a symmetrical introduction of the rolling stock to and through the rolling apparatus.
