If you’ve had your Roborock for a while, then you may experience the laser and motor not working quite like it should. Especially if have pets, as that dirt and dust (and other things) can get into the module on top of the robot vacuum and cause it to not clean properly. Potentially running into furniture, walls, etc.

Luckily, there is a way to fix this issue. It mostly has to do with the LDS motor on your Roborock robot vacuum. And below, we’ll show you how to replace it. This is the easiest route to go, as replacing the entire laser module can be quite cumbersome and expensive. We’d only recommend doing this if your vacuum is outside of the warranty phase. Otherwise, you can just send it into Roborock to get it fixed.

First, remove the dustbin and the cleaning tool from the robot vacuum.

Next, you’re going to need to remove the cover that goes over the power button, dock and spot cleaning buttons. You will need to use a bit of force to do this, but it will just snap right off.

Now to put it back together, just redo everything we just mentioned. Starting with reattaching the LDS Motor to the module with those two screws. Then replace the four screws that puts the module back onto the robot vacuum.

Afterwards, you’ll need to use the five screws for the LDS protective cover and put that back in place.
