1. Improve walking stability: The wear of the old driving wheels leads to the weakening of grip. After replacing the sweeping robot wheels, the sweeping robot's ability to climb slopes and overcome obstacles is enhanced, and it is not easy to slip and ze. 2. Reduced cleaning dead spots: Worn drive wheels can affect steering accuracy. Replacing the robot vacuum cleaner wheels ensures that the robot steers flexibly and cleans the corners and edges more thoroughly. 3. Extend life: The aging drive wheel aggravates the load of the motor. After replacement, it can reduce the running resistance, reduce the loss of core components, and prolong the life of the whole machine. 4. Reduce operating noise: The friction between the worn drive wheel and the ground is easy to produce abnormal noise. Replacing the material of the sweeping robot wheel to be more suitable for the ground makes it run smoothly and quietly, without disturbing the home environment.
