[L40 Ultra] Side brush wrapped

Hello, my robot will no longer resume cleanings. It keeps detecting the side brush as wrapped. I have removed it, brushed free any debris and even used compressed air to clean the brush apparatus and the brush port. I've ensured all entangled hairs are removed and even snipped the brushes' stray ends, but it is still stuck on "Side brush wrapped".

pull the brush out completely, like you're replacing it, and check to see if something is wrapped around it, up inside. mine was completely wrapped in hair.

Same issue, and I've even tried taking it apart to make sure so components are installed correctly. Still getting the error message. Is this a new firmware bug?
Hi,

Let's work together to resolve this by following the steps below:

1. Check for jams: Please check if the robot is stuck under furniture or if the side brush is obstructed. If stuck, gently move the robot to an open area and ensure the side brush can rotate freely.
2. Clean the side brush: If the robot isn't stuck, please inspect the side brush for any tangled hair or debris that might affect its rotation. Remove the side brush and carefully clean all hair, dust, and foreign objects. You may use scissors to carefully cut away any wound hair.
3. Reinstall the side brush: After cleaning, please reinstall the side brush securely onto the main unit. Ensure it's properly positioned, then restart the robot manually and begin a new cleaning task to verify normal operation.

If the issue persists after completing all the steps, it may be related to a hardware problem.

If the issue remains unresolved and you are a user in North America, you can contact support.na@dreame.tech for support. Also, kindly provide a video of the problem to help with diagnosis.

This has to be a problem they know about.  I bought two  of these and now one is doing the same thing.  I’ve done all the so called fixes and nothing. I even bought new side brushes.  This is ridiculous as these are expensive
