[0035] In the above embodiment, when one of the two sets of hub elements 41 is powered and the other is an auxiliary wheel set, it is used as a driving force for rotation to drive the body 1 and the cleaning assembly to clean the floor. When both sets of hub elements 41 are powered, both sets of hub elements 41 use hub motors when rotating for cleaning, and can complete the rotation action under differential rotation. When it is necessary to travel, they can rotate in the same direction for travel.

[0036] A cleaning robot, wherein a cleaning element 5 of the cleaning robot is arranged on the periphery of a body 1, which means that the cleaning element 5 can perform comprehensive coverage cleaning around the body 1. Whether it moves in a straight line or a curve, the cleaning element 5 can maintain contact with the ground and cover the cleaning area around the entire body 1, thereby improving the comprehensiveness and consistency of the cleaning effect. The power component 4 is used to drive the movement or rotation of the body 1, so that an automated cleaning operation can be achieved. Through preset programs and algorithms, the cleaning robot can perform cleaning tasks autonomously without human intervention. This can improve the efficiency and convenience of cleaning and reduce the burden of manpower.
