AI Technical Summary

Technical Problem

When existing cleaning robots encounter heavily polluted areas, the drive wheels, side brushes, and roller brush components are easily contaminated, affecting the cleaning effect and efficiency.

Method used

After the cleaning robot detects a heavily contaminated area, it moves in reverse, with the drive wheels and mop rotating in the same direction, and adjusts the mop's position to cover the driving wheel's walking area, ensuring that the mop contacts the heavily contaminated area first to reduce component contamination.

Benefits of technology

By moving backward and adjusting the mop position, the contamination of the drive wheel, side brush and roller brush assembly is reduced, the cleaning effect and efficiency are improved, repeated cleaning and cross contamination are avoided, and path planning is optimized.

Abstract

The invention provides a cleaning method of a cleaning robot, the cleaning robot and a cleaning system, and relates to the technical field of intelligent robotics.The cleaning robot comprises a mop assembly and a driving wheel, the mop assembly is provided with a mop and a driving part for driving the mop to rotate, and the driving wheel is located in front of the mop with the advancing direction of robot walking as the benchmark; the mop is provided with a first position located inside the machine body and a fourth position at least partially located outside the machine body, and in the cleaning process of the robot, when it is detected that a heavily-polluted area exists, the robot is controlled to advance at least partially in a backward mode based on a preset cleaning path so as to clean at least part of the heavily-polluted area through the mop. The heavily polluted area is close to the wall; the rotating direction of the driving wheel is the same as the rotating direction of the mop cloth in the backward advancing process, the synchronous rotation can accelerate the moving speed and reduce the standing time in heavy dirt, and in the backward advancing process, the mop cloth is located at the fourth position, so that the cleaning area of the mop cloth covers a larger area, and the cleaning effect is improved.
