In connection with fig. 11, the width of the buffer structure 82 is L2, the width of the projection of the scraping element 84 on the horizontal plane is L1, and in the case of the scraping element 84, the buffer structure 82 is installed such that the width L2 thereof covers the width L1, because the position where the rolling brush cover 80 with the scraping element 84 is mainly in contact with the surface to be cleaned is at the scraping element 84, which facilitates the scraping of the scraping element 84 on the surface to be cleaned, and the extension length of the buffer structure 82 toward the surface to be cleaned protrudes from the surface of the rolling brush cover 80 and is lower than the extension length of the scraping element 84 toward the surface to be cleaned, so that the rolling brush cover 80 can be effectively protected, and the scraping element 84 can be prevented from being turned over the threshold or over the protrusion of the surface to be cleaned toward the rear of the rear side wall 802. In other embodiments, the width L2 of the bumper 82 may extend to approximately the width of the roller brush cap 80. The buffer structure 82 may be a thin strip of hair or other soft material attached to the surface of the roller brush cover 80.
In some embodiments, the rolling brush cover 80 further comprises a chaste tree 83, the chaste tree 83 spans the rolling brush 40, one end of the chaste tree 83 is fixedly connected to the front side wall 801 of the window 81, and the other end of the chaste tree 83 is fixedly connected to the rear side wall 802 of the window 81. When the cleaning member of the roll brush 40 is a brush strip, the contact portion of the brush strip comprises a first notch 468 disposed between the first rotation section 416 and the third rotation section 418 and a second notch 478 disposed between the second rotation section 417 and the third rotation section 418. When the rolling brush cover 80 and the rolling brush 40 are mounted on the mounting seat 90, the chaste tree 83 is mounted on the first notch 468 and the second notch 478. On one hand, the arrangement of the chaste tree twigs can further fix the rolling brush 40, and on the other hand, the long linear objects can be effectively prevented from being rolled into the rolling brush 40 in the cleaning process of the cleaning robot, so that the rolling brush 40 is damaged or the cleaning robot cannot work normally.
