I guess you didn’t actually open it to check the lidar “belt”, but the lidar does spin?
Might want to use compressed air to blow out the holes in lidar tower just in case. Mine started acting up even though there was no visible blockage, blowing it out took care of the issue.
I agree that the vacuum motor should still start even if it’s a bit dirty, but not sure what happens if it was not spinning at all or if it wasn’t getting a proper signal from the lidar unit itself.
If you have a camera with nightvision (e.g. Wyze cam), you can check that the lidar is casting its beam.
Since it’s past warranty, it might be worth taking it apart to look inside. But first it might be worth disconnecting the battery for 30 seconds (go longer to be safe) to see if a full hardware restart helps. It probably doesn’t matter, but I would turn it off first.
Here’s a recent opening:
I’ve seen at least a couple (Wyze) tear-downs on youtube.
Using the below keywords on aliExpress, there are lots of available parts. And Amazon at much inflated prices. I don’t know of anyone who’s replaced their motor.
“STYTJ02YM motor”. Note there are a couple very similar looking models, see below…
Keywords:
- Mijia STYJ02YM (viomi-v7)
- Mijia STYTJ02YM (viomi-v8) also known as the Xiaomi Mi Robot Vacuum-Mop P or Viomi V3 (non-Max)
- Wyze appears to be based on the STYTJ02YM.
