含义
扫地机器人悬崖传感器（防跌落传感器）读数异常。E6 表示一个或多个悬崖传感器始终被触发或完全无响应。悬崖传感器通常为红外线测距传感器，安装于机器人底部边缘，用于检测台阶边缘以防止跌落。
常见原因
- 悬崖传感器表面被灰尘或杂物覆盖，导致红外发射/接收受阻。
- 悬崖传感器 LED 或光电接收管老化故障。
- 机器人底部传感器周围的装饰条或检测窗盖板脱落。
- 悬崖传感器信号线插头松动。
- 主板传感器检测电路故障。
- 传感器被地面反射面（光滑瓷砖、镜面）干扰，误判为悬崖。
自助排查
- 将机器人翻转，用干棉签或软布清洁机器人底部四个悬崖传感器（黑色发射/接收窗口）。
- 检查机器人底部传感器窗口附近的盖板是否脱落——如有脱落重新装好。
- 将机器人放到不同地面（普通地板而非高反射地面）测试，排除反光干扰。
- 重启机器人——有时临时信号干扰可恢复。
- 如果清洁后仍报 E6，悬崖传感器可能已损坏，联系 TCL 售后更换底部传感器组件。
English
Meaning
The cliff sensor reading is abnormal. E6 indicates that one or more cliff/drop sensors are either always triggered or not responding at all. Cliff sensors are typically infrared distance sensors mounted on the bottom edge of the robot to detect stair edges and prevent falls.
Common Causes
- The cliff sensor surface is covered with dust or debris, blocking the infrared transmitter or receiver.
- The cliff sensor LED or photodetector has aged or failed.
- The trim or detection window cover around the bottom sensor has fallen off.
- The cliff sensor signal wire connector is loose.
- The sensor detection circuit on the main board is faulty.
- The sensor is being interfered with by reflective floor surfaces (polished tiles, mirrors), falsely detecting a cliff.
Self-Check Steps
- Flip the robot over and clean the four cliff sensor windows (black transmitter/receiver openings) on the bottom with a dry cotton swab or soft cloth.
- Check whether the cover near the sensor windows on the bottom is detached — reattach it if found loose.
- Test the robot on different floor surfaces (normal flooring rather than highly reflective surfaces) to rule out reflective interference.
- Restart the robot — occasional signal interference may be resolved with a power cycle.
- If E6 persists after cleaning, the cliff sensors may be damaged. Contact TCL after-sales to replace the bottom sensor assembly.
