摘要： A cleaning head for use with a floor cleaning machine comprises first and second cleaning tools, at least one motor and a cleaning tool support. The at least one motor is configured to respectively drive rotation of the first and second cleaning tools about first and second horizontal axes. The first and second cleaning tools each have an exterior cleaning surface configured to engage the floor during floor cleaning operations. The cleaning tool support is configured to support the first and second cleaning tools for movement of the first and second horizontal axes relative to each other in a plane that is transverse to the first and second horizontal axes. Another embodiment of the invention is directed to a floor cleaning machine that includes embodiments of the cleaning head.

摘要： A sweeping machine for picking up debris from a surface includes a frame and wheels attached to said frame to support the frame of the sweeping machine over the surface being swept. A cylindrical brush is rotatably attached to said frame. The cylindrical brush includes a pattern of rows of sweeping material having N sections that have a first spiral in a first direction and N+1 sections of the brush that have a second spiral in a second direction. Two of the N+1 sections having the second spiral are located on the ends of the brush. The spiral is selected so that it augers or moves debris from a desired or selected side of the sweeping machine toward the center of the brush. The sweeping machine also includes a mechanism for rotating said cylindrical brush.

摘要： A floor scrubbing machine uses two parallel cylindrical scrub brushes. Each brush is rotated by a separate drive means, and these are at opposite ends of the brushes. This balances the weight of the drives so the brushes exert a uniform pressure on the floor. The brushes are axially offset enough that each brush extends out as far as the drive means of the other brush, thus permitting the machine to scrub close to a wall on either side. The brushes have a more aggressive bristle fill at their ends which extend out under the drive means, where only one brush is scrubbing the floor, so the appearance of the scrubbed floor is essentially the same where scrubbed by one brush as where scrubbed by two brushes.
摘要翻译：地板擦洗机使用两个平行的圆柱形洗刷刷。每个刷子通过单独的驱动装置旋转，并且它们在刷子的相对端。这样平衡驱动器的重量，使刷子在地板上施加均匀的压力。刷子被轴向偏移足够大，使得每个刷子延伸出直到另一个刷子的驱动装置，从而允许机器靠近两侧的壁。刷子在它们的端部具有更积极的刷毛填充，其在驱动装置下延伸出来，其中只有一个刷子在擦洗地板，所以洗刷的地板的外观基本上是相同的，由两个刷子擦洗的一个刷子擦洗。
