Abstract
A vacuum cleaning tool, especially a suction nozzle for the floor, is provided. The tool includes a housing having a suction chamber that is connected to a vacuum cleaning unit by a connector. Disposed in the suction chamber is a brush roller, the bristles of which extend through a suction opening. The brush roller is rotatably disposed in the housing between lateral mounting pieces, which are held by respective pivot arms in such a way on a pivot element provided in the housing that the brush roller can be pivoted out of the suction chamber about a pivot axis that is disposed approximately parallel to the brush roller. One of the pivot arms is detachably connected with the pivot element via a plug connection, which is provided with electrical plug contacts via which the electrical line of an electric drive motor disposed in the brush roller can be connected with an external power source.
