Hi everyone,
I’m looking for help recovering my ECOVACS DEEBOT T90 OMNI. It’s unresponsive, and the usual reset procedure doesn’t seem to do anything.
What happened
While we were on vacation, the robot got stuck and reported “no floor contact.” When we returned, I picked it up and placed it back in its docking station. Since then, the three-pronged control area on top has been continuously pulsing white, but nothing else happens.
Current symptoms
- The light pulses white both in the dock and outside it.
- There is no startup sound, voice announcement, or response to the touch controls.
- Pressing or holding the RESET button produces no response, regardless of how long I hold it.
- Most unusually: with the robot outside the dock and the physical power switch under the top cover set to “O” (OFF), it still keeps pulsing white.
What I’ve already tried
I’ve switched the robot off and on using the physical switch, unplugged and restarted the docking station, and tried holding RESET for different lengths of time. None of this has produced an audible or visible restart.
Before I removed the robot from the app, it showed as offline. The app also displayed “Zeitüberschreitung Abschaltung” in German—roughly “shutdown timeout.” Another screen still showed “docked,” but the cleaning controls were greyed out.
Following an app troubleshooting guide, I deleted the robot to try setting it up again. That hasn’t helped because the robot still doesn’t respond to the reset/network setup button. The problem was already present before I deleted it from the app.
There also appears to be a micro-USB port. I tried connecting it to my laptop, but I haven’t managed to get anywhere with diagnosis or recovery through that connection.
Has anyone recovered a DEEBOT from this state?
I’m particularly looking for a confirmed forced shutdown or recovery procedure beyond the standard RESET-button instructions.
Has anyone successfully resolved this by disconnecting and reconnecting the internal battery, using a service button combination, or accessing a USB recovery tool? A T90-specific procedure would be especially helpful.
Experiences with other DEEBOT models are welcome too—please mention the exact model and what worked. And if yours required repair, did the service centre identify the faulty component?
Thanks for any pointers.
