    • A vacuum cleaner with a floor traveling head having a housing, a rotatable brush, and two motors. The housing has a suction inlet with an entrance at its bottom and a separate pocket in the bottom of the housing for the rotatable brush. A wall of the housing separates the pocket from the suction inlet such that the entrance to the suction inlet has a relatively small area to maximize vacuum pull at the entrance. The suction inlet has a lower section with straight wall sections that are angled to form smaller areas at the lateral ends of the suction inlet. The suction inlet has an exit aperture directly into a collection assembly such that air velocity increases from the lower section to the upper section and then decreases from the upper section into the collection assembly.
    • 具有地板行进头部的真空吸尘器具有壳体,可旋转刷子和两个电动机。 壳体具有在其底部具有入口的吸入口和用于可旋转刷的壳体底部中的单独的凹部。 壳体的壁将袋与吸入口分开,使得到吸入口的入口具有相对较小的面积,以使入口处的真空拉力最大化。 吸入口具有下部,其具有直壁部分,其成角度以在吸入口的侧端处形成较小的区域。 吸入口具有直接进入收集组件的出口孔,使得空气速度从下部增加到上部,然后从上部减小到收集组件。
