Manual replacement of the Roborock Lidar motor to solve the Error 1 problem (Video)

This robot has definitely received relatively high praise in most user reviews. If you own one Roborock S5 or S5 Max, you should be able to understand what I'm talking about. However, one of the biggest defects of this robot vac is that its Lidar component has a major quality problem, and there are many users who encounter the situation that the laser unit stops rotating and then reports Error 1, which makes it completely impossible for users to use it properly.

Some users may not know that the Lidar component is almost the most important part of these robots, equivalent to the human eyes, and if this component fails, the robot is completely useless. The Error 1 we mentioned above is that the radar rotor in this Lidar component is not rotating properly.

A Google search for this issue reveals that Roborock officially has a web page describing:

What should I do when error 1 occurs?

Roborock Error 1: Turn on the robot and watch to make sure the laser unit is spinning.If the laser unit is not spinning, gently rotate it manually, then restart the robot.If you continue to experience this error, contact Roborock Customer Support.

Did you read it and think they didn't provide any valid information? Indeed, if your device is out of warranty, you may not be able to get a free solution from the official after-sales service. So when you encounter such a problem, you can't just throw the sweeper away, right?

Of course not, there are many professional players on the Internet who give a good solution: manually replace the motor that drives this radar rotor! Yes, it is this motor may have quality problems, relatively short working life, just replace it, the robot will be back to normal.

So, where to get these replacement motors? Actually many Chinese sellers sell these parts on the internet, you just have to go to AliExpress or Amazon and search for them. As a professional spare parts seller, we techTongBo sell this motor in our own stores, and they are very cheap and works very well.

Today we will use the video to demonstrate the entire replacement process, we will also go to the text of the entire replacement process to do some introduction:

(We even tried to provide a demo video in 4K resolution)

Some points to be reminded

  • The whole process, the tool you need is basically a driver (which is usually included in the seller's replacement set), and then I suggest you use an electric screwdriver, which will save you a lot of time and effort.

  • The most difficult step is the first step (everything is difficult at the beginning), especially this roborock s5 that we operate, its cover is very difficult to remove, the writer took a lot of effort to remove it successfully (they are connected by plastic clips, no screws).

  • After opening the top cover of the body, use a screwdriver to remove the screws, there are a few screws are well hidden, not easy to find, you need to rip out the soft rubber plug on top of the screws.

  • All the screws are the same interface, only a small number of length slightly longer. It is very good to distinguish them, so there is no mistake in the installation process after the replacement is completed.

This motor has great sales on e-commerce platforms, so it makes one wonder if Roborock's quality of the motor on the original equipment is good enough. We hope more users won't lose their robots because of this motor failure and can try their hands at fixing it and getting it back to work!
