Abstract
A cleaning robot including a body, a driving assembly for driving the cleaning robot to move, and a first cleaning assembly for cleaning a floor is disclosed. The first cleaning assembly includes a rotating shaft, mounting members mounted at both ends of the rotating shaft, a brush body provided outside the rotating shaft, and the rotating shaft is rotatable along with rotation of the mounting member, driving the brush body to clean the floor. The brush body includes a soft bag of an internal hollow structure and a brush portion extending outward from a surface of the soft bag, such that during cleaning, elastic space of the first cleaning assembly is increased, and a frictional force between the first cleaning assembly and the floor is reduced, thereby effectively protecting the floor and increasing the service life of the first cleaning assembly.
