In some embodiments of the invention, a shaft sleeve 12 is provided on the floor brush housing 1, and the connecting member 3 is pivotally connected to the shaft sleeve 12. For example, a boss 12 is provided on the left side wall of the floor brush housing 1, and the first pivot hole 41 described above is provided on the boss 12. As another example, the aforementioned ball socket 45 is provided on the boss 12. Thus, by providing sleeve 12, the fabrication of the associated pivot structure on sleeve 12, such as first pivot hole 41 or ball socket 45 described above, may be facilitated.
