    • A vacuum attachment for a vacuum cleaner including a housing having a vacuum channel. A roller is rotatably and displaceably disposed in a region of the vacuum channel and driveable during a vacuuming operation. The roller includes at least one of bristles and baffle walls configured to be in partial contact with a floor covering during the vacuuming operation. At least one roller magnet is disposed on the roller at least one end thereof. At least one housing magnet is non-rotatably disposed on the housing axially adjacent to the at least one roller magnet and configured to interact with the at least one roller magnet so as to alternately at least one of attract and repel the roller so that the roller performs an oscillatory motion as it rotates.
    • 一种用于真空吸尘器的真空附件,其包括具有真空通道的壳体。 辊可旋转地且可移动地设置在真空通道的区域中并且可以在抽真空操作期间驱动。 辊子包括刷毛和挡板壁中的至少一个,其构造成在真空操作期间与地板覆盖部分接触。 至少一个辊子磁体设置在辊的至少一端上。 至少一个壳体磁体不可旋转地设置在壳体上轴向相邻于至少一个辊子磁体并被配置为与至少一个辊子磁体相互作用,以便交替地吸引和排斥辊子中的至少一个,使得辊子 在旋转时执行振荡运动。
