Background
During the working process of the cleaning robot, a user does not need to operate the cleaning robot in real time generally, and along with walking in the area to be cleaned, the cleaning robot can automatically suck dust and debris. The cleaning robot is more and more popular and widely used by consumers due to the advantages of small volume, flexible movement and automatic operation.
The existing household cleaning robot can not lift the rolling brush when cleaning uneven surfaces, so that concave places can not be cleaned, and the cleaning robot is limited to only clean flat ground. The rolling brush of the existing household cleaning robot generally comprises two types, namely a first working mode: the rotating direction of the rolling brush is the same as that of the driving wheel when the household cleaning robot moves forward, and the rolling brush cleans garbage backwards when the household cleaning robot moves forwards. A disadvantage of this mode of operation is that if the volume of the waste particles exceeds the maximum area that can be tolerated by the gap between the roller brush and the floor, the waste will not be able to be cleaned. In the second mode, the rotating direction of the rolling brush is opposite to that of the cleaning robot when the rolling brush moves forward, although the process avoids the defect that the rolling brush cleans backwards, the rotating speed of the rolling brush is high, and the front side of the dust collection opening is not shielded, so that the rolling brush cleans forwards, the garbage, particularly large-particle garbage, is easily pushed away from the dust collection opening, and meanwhile, dust swept by the rolling brush is not easily sucked into the dust collection opening.
