[L40 Ultra] Does not work

Mapped the house out of the box in first run. now the robot won't come off the dock without reversing and saying it's wheels are off the ground. the wheels are on a flat surface and all the sensors are clean and we've done several factory resets and it does the same thing every time. It will do this even when it's not started from the dock.

Since you performed a factory reset, double-check to make sure your firmware is up-to-date.

Thanks for the picture. I was looking to see if there was any material covering any of the cliff sensors which seems to be the root issue here. Was the robot able to successfully map your house?

I checked and I have the latest version of firmware and there's nothing in the wheels and I tried to remap the house just now and it did the same thing.

It would be my guess that one of the sensors has failed, and unfortunately this does happen from time to time, even worse when it's brand new out of the box. What happens if you run it on carpet/tile

You most likely need to contact customer service for an exchange or warranty repair: https://www.dreametech.com/pages/dreame-contact-us. If thru a 3rd party/vendor I'd contact them for an exchange.

There's no exchange on these so we are returning it and not getting another one as this has been too much of a hassle for our first robot vacuum.
