If a vacuum cleaner robot starts making loud or unusual noises during operation, it could indicate a complication. These noises can be caused by various factors, such as a loose part, a foreign object stuck in the robot's mechanism, or a worn-out motor. To address this issue, users should first check for any visible obstructions or loose parts and remove or tighten them accordingly. If the noise persists, it is advisable to contact the manufacturer for further guidance or to arrange for repairs.
