WHAT IS A D-TOF (LiDAR) SENSOR MALFUNCTION and how do I fix it?

Have you got a robot vacuum and it’s throwing up an error called “D-TOF sensor malfunction”

what is a D-TOF sensor malfunction and how do I fix it?

Hopefully this video is helpful and gets you back up and running!

This is on an Ecovacs Deebot T9+

If the clean doesn’t work you can always try replacing the sensor with a new 1️⃣ 👇

Note this may also help clear a fault that causes your robot to maping to play up.

I was able to repair my vacuum by following your video. Thank you!

Thanks for sharing this video! My vacuum was starting to rotate its floorplan by 45 degrees. Last time this happened I sent it in for a warranty repair and they said they replaced the LIDAR. It's now out of warranty and the same issue has started happening. I found your video, pulled it apart and wiped the inside of the LIDAR cover and for the past 10 days it has been working fine. Thank you so much!

I just had this same problem with mine. With the covers off the sensor I could see that it was trying to spin but kept getting caught up. I took the black rubber band off that runs around the bottom of the sensor and around the drive wheel and gave it a clean and brushed out the groves that it sits in and refitted it. And now it's happy and back to vacuuming 🙌

*Potential fix for those still struggling!*
I tried dusting the cap and device with canned air. I tested running the system without the protective cover and the TOF sensor turned super slow and would stop / start. It's supposed to spin several times pers second.

I removed the rubber band belt with tweezers. I carefully removed the TOF module by unscrewing the three silver screws. I gently pulled out some wire slack and unplugged the connector. Now the module is separated from the vacuum.

The goal is to lubricate the motor. First, I taped the black spinning puck with the lenses facing away from the motor. Next, I took canned silicone lubricant and sprayed the smallest amount possible into the gap under the cream colored motor wheel. Then, I spun the motor wheel by hand in order to work the silicone lubricant into the motor. I wiped away any excess and I repeated this step one more time.

Finally, I assembled the module back together and back onto the vacuum. I tested the assembly without the protective cover again and the TOF puck spun beautifully. Reassemble the cover parts and it's working great.

I found the video. Thank you for good explanation. If you could also can you explain why and how can fix the vacuum cleaner if it is not spraying water

I keep getting this malfunction notice but my vacuum doesn’t move at all, it just sits there and eventually comes up with the notice. I even replaced the part with a new one and it still doesn’t work.
