Silly firmware upgrade-- now mops down and robot dock!!!!

I have a DreameBot L10 Ultra running firmware 4.3.9_1624.

After a recent firmware change, the robot has developed a serious docking problem that appears to be caused by the mop-control sequence.

When returning to the base station, the robot lowers the mop pads and spins them while it is attempting to climb the dock ramp. The pads contact the ramp and create enough friction that the drive wheels lose traction. The robot therefore cannot climb into the dock and cannot charge.

The diagnostic result is very clear:

Mop pads installed: fails to climb/dock.
Mop pads removed: docks normally.

The dock has not moved and the hardware setup has not changed.

I am aware that Dreame has changed mop rotation/lift behaviour during docking through firmware on L10-series robots before, and there are other users reporting similar problems where lowered/spinning mop pads interfere with the docking ramp.

This is not acceptable behaviour for an otherwise functional robot. A software update should not render automatic docking and charging unusable.

@Dreame Support: please escalate this to the firmware team.

I am specifically requesting either:

• a rollback from firmware 4.3.9_1624 to the previous working firmware; or
• a firmware fix correcting when the mop pads are lowered/spun/retracted during the docking sequence.
  

I can provide a video showing the robot failing with the mop pads fitted and immediately docking successfully after the pads are removed, as well as device logs and the robot serial number privately.

Please do not treat this simply as a dirty sensor or charging-contact problem. The problem is mechanically reproducible based on whether the mop pads are installed.

That's a frustrating one, especially after an update. Nothing I can do on the firmware side — email dreamesupport@dreame.tech with the video and your SN and see what they say.

Hello,

We sincerely apologize for the inconvenience caused.

We would like to confirm whether you have previously contacted our after-sales service team via aftersales@dreame.tech but have not received a response.

To further verify your situation and avoid any service conflicts or impact on the handling of your device caused by repeatedly reporting the same issue, please provide your service ticket number (usually a series of digits beginning with 83).

Once we receive this information, we will check whether there is already an active service process in progress for your case. If no existing service record is found, we will be more than happy to assist you further and provide the necessary support.

Thank you for your understanding and support. We look forward to your reply.

I have had a similar issue late last year , i  removed the vacuum from the app via a factory reset, when i set it up; as if new, it corrected the issue.

So after much back and forth, this is the answer I get from Dreame. Hard to believe that 30 emails later they are back to pretending that this isn't their fault and that I should "ensure the base station is placed horizontally A thin anti-slip mat can be placed in front of the base station." If the problem persists, we will arrange after-sales repair for you.Since your device is currently out of warranty, the repair will be a paid service. VERY FRUSTRATING when you know it is their fault...
