1.Improved cleaning results: Worn wheels may cause the robot vacuum cleaner to move unsmoothly on the ground, which can affect its cleaning results. Replacing the robot vacuum's wheels can improve mobility and allow the robot to sweep all types of floors more efficiently. 2.Prevents seizure: Aging or damaged wheels tend to get stuck on carpets, stairs, or other obstacles. By replacing the robot vacuum cleaner's motor wheels, the robot can more smoothly cross obstacles and reduce stuckness. 3.Extend the life: Keeping the various parts of the robot vacuum cleaner working properly, including the wheels, can extend the overall life of the machine. Regular replacement of worn wheels prevents additional damage to other components. 4.Improve driving stability: Replacing the wheels of the sweeping robot can improve the driving stability of the sweeping robot, reduce violent shaking, and improve the balance during cleaning, so as to avoid cleaning omissions caused by instability.
