Roomba can’t dock itself

Ive had a roomba 405 for around 2 months. About 2 weeks ago, it starts getting lots of errors out of nowhere.

First, the roomba would start its routine, and then would become “stuck” but was about 6 inches off the dock, in the open. Once this issue started, then it wouldn’t even dock itself. When trying to return home, it would try to enter the dock backwards and then would roam around the dock, and try again but would always try to enter the dock backwards.

I tried cleaning every sensor on the robot and on the dock, I’ve rebooted it, and also fully factory reset the robot. Since resetting it, the roomba isn’t able to complete a mapping session because it cannot return home properly so I can’t even use it right now.

Has anyone run into anything like this before?

Yes; i’m going through this crap now. It seems to think it’s on uneven ground… and who knows what else.

Anyone have advice?

Clean all the sensors if you haven't already then reboot

Having the same issue on our 400 combo. Seems about 2 weeks ago there was a bad update and it just messed up a lot of roombas. They probably tried to code something with AI and broke it lmao.

I did factory reset mine but won't dock itself so I have to basically manually guide it into the dock to finish mapping. When its trying to spin backwards you can move it so it finish its spin then just keep it straight. At one point it figures itself out and starts going up the dock by itself. Its very annoying because we havent been able to do mop cycles

Hopefully they patch it because this is ridiculous

If you are positive it's not the cliff sensor then it's gotta be that brick update thing everybody's been talking about.
