AI Technical Summary

Technical Problem

Existing cleaning robots increase energy consumption and noise when cleaning carpeted areas by increasing the suction power of the fan, and they are unable to effectively remove dirt such as pet hair and fine sand from the roots of carpet fibers, resulting in incomplete cleaning.

Method used

After detecting the carpet area, the roller brush is controlled to descend to a second position closer to the carpet surface, and the shielding piece is adjusted to a third position to optimize the airflow in the ventilation channel, enhance the physical cleaning effect of the roller brush on the carpet fibers, reduce the ventilation area, improve local suction, and avoid increasing the fan power and suction.

Benefits of technology

Without increasing energy consumption and noise, it improves carpet cleaning efficiency, effectively removes deep-seated dust and debris from carpets, reduces noise and energy consumption, extends the lifespan of the fan, and enhances the user experience.

Abstract

The application provides a cleaning robot control method and device, robot, medium and product, relates to the technical field of cleaning equipment, and the cleaning robot comprises a rolling brush assembly and a shielding piece. The rolling brush assembly comprises a dust suction cavity and a rolling brush. The dust suction cavity and the surface to be cleaned form a ventilation channel. The rolling brush has a first position and a second position. The second position is the position of the rolling brush descending from the first position to be close to the surface to be cleaned and at a second height. The shielding piece has a third position and a fourth position. The ventilation area of the shielding piece at the third position is smaller than that at the fourth position. During the cleaning process of the cleaning robot on the cleaning area, if a carpet area is detected, the rolling brush is controlled to be closer to the carpet surface at the second position, and the shielding piece is adjusted to be at the third position to optimize the airflow of the ventilation channel, so as to clean the carpet area, effectively improve the cleaning effect of the carpet, and avoid the problems of high energy consumption and noise caused by increasing the suction force.
