Roborock S8 MaxV Ultra: LiDAR won’t spin

Wed, 27 Nov 2024 08:03:10 -0700

The LiDAR will stop spinning. This seems to be a common problem with their design. Sometimes it’s debris that gets into the housing. Others the motor blows out. There are YouTube videos showing repairs on older models but none on this model. A video would be helpful as the design seems to be slightly different.

Also, any advice on upgraded replacement parts to fix the weak points would be helpful.

Roborock S8 MaxV Ultra: Dustbin empty cycle stuck

Tue, 09 Sep 2025 08:28:53 -0700

I’m having a persistent issue with my Roborock S8 MaxV Ultra and hoping someone here has run into the same thing or has a fix.

Problem Summary:

Whenever the robot returns to the dock to auto-empty the dustbin, it gets stuck in the emptying cycle. Physically, I can hear the dock vacuum start and stop, but in the Roborock app, the emptying process never finishes. This causes two major problems:

The robot won’t start charging.
If it returns mid-cleaning, it won’t resume cleaning after docking.

Unplugged the dock and plugged it back in.
Cleaned all filters and checked for obstructions.
Power-cycled the robot.
Verified the dustbin cover is properly installed.
Checked for blockages in the dock and suction path.
Ensured the robot isn’t in Do Not Disturb (DND) mode, and verified every setting in the app.

I can manually stop the emptying process via the app, but doing so resets the cleaning cycle, meaning it won’t resume where it left off.
The dock’s status light doesn’t show any errors, and the vacuum seems to dock correctly.
I suspect the issue might be with the signal or sensor that tells the robot the emptying process is complete. It seems like the robot never gets that confirmation.
