1. Improved mobility and flexibility: After long-term use, the travel wheels may lose their dexterity due to wear and tear, causing the robot to move slowly or get stuck while cleaning. Replacing the robot vacuum's wheels can restore mobility and improve cleaning efficiency. 2. Enhanced grip: Replacing robot vacuum drive wheels can provide better traction on various floor types, including tiles, wood floors, and carpets, helping to prevent slippage and ensure stable movement. 3. Improved cleaning results: Functional travel wheels help the robot navigate obstacles and transitions more effectively, allowing for more complete coverage and better overall cleaning performance. 4. Noise reduction: Worn travel wheels may produce noise during operation, affecting the quietness of the environment. Replacing the wheels can help reduce operational noise for a quieter cleaning experience.
