The guide wheels 60 include a plurality of guide wheels 60, a part of the guide wheels 60 are disposed on two sides of the rolling brush housing 11, and the connecting brackets 70 are connected to the guide wheels 60 and the rolling brush housing 11, respectively.

Specifically, the guide wheel 60 further comprises a movable wheel 61 and a movable connecting frame 62, the movable connecting frame 62 is sleeved on the movable wheel 61, and the movable wheel 61 can roll relative to the movable connecting frame 62. The movable connecting frame 62 includes a movable connecting rod 621 extending in a direction perpendicular to and away from the ground. One end of the connecting bracket 70 is connected to the top plate 112 of the rolling brush casing 11, and the other end is movably connected to the movable connecting rod 621 of the movable connecting bracket 62. The guide wheel 60 is rotatable about a movable connecting rod 621. The guide wheel 60 may also adjust a relative position with the connection bracket 70 through the movable connection rod 621 to change a distance of the cleaning device 100 from the ground, so that the brush bar 22 of the drum brush assembly 20 can contact the ground and maintain interference compression at a certain distance from the ground when the cleaning robot 1000 performs a cleaning task, thereby improving a cleaning effect. The distance of the interference compression is not limited and may be set, for example, between 4 and 6 millimeters. In this manner, by the arrangement of the guide wheel 60 and the connecting bracket 70, the guide wheel 60 can support the entire cleaning device 100 during the cleaning process of the cleaning robot 1000, so that only the brush bar 22 of the roller brush assembly 20 is in contact with the ground while allowing the cleaning device 100 to slidably travel.
