iRobot Braava 380T - 3 Beeps, Then 6 beeps, Then no movement

[Lime795]

So i have an iRobot Braava 380T.

I have tried everything on iRobot's support page, and would really like to not have to spend an upwards of 200+$ for a replacement.

Rundown of what happened:

Was working fine yesterday, placed it on the cradle, let it charge, was fully charged the next day.

Placed it on the floor in mopping mode with water to clean.

It moved barely, beeped three times, then six times, then shut off. And now all it does is make the blue lights "stop", then "dance" then stop again, then beep three times. This happens in both modes.

This has driven me nuts, any solutions?

The Braava has an off normal sensor. The off normal condition has to do with the cleaning cloth and how it is placed. Check for bunching up that prevents proper seating of the pad assembly.

Tried that as well, still fails to run.

Have you tried removing the cloth completely ?

Yep. Even ran it without a cloth, same problem.

Also called iRobot, they just said "Get a new one [sic]"

You might check on Amazon.com and ebay for a used one. The problem you have run into with the one you have is that there is not a lot of troubleshooting info available as to what hardware might be causing the error.

I have registered here for the sole purpose of helping people who will have this issue in the future.
I had exactly the same issue, where the Braava (390t in my case) would clean for a minute, then red led on power button, return to start point, and three beeps.

The solution here is simple, replace the battery for a new one. The problem is that the Braava uses NiMH batteries, which are not optimal for this application. This means that in order to properly maintain them, they need to be fully discharged and then fully recharged, or they will get memory effect.

In my case, not only i did put it to charge immediately after cleaning (even if it only cleaned for 10 minutes), but i left it without the charger connected for two weeks. The result of this was the red light and three beeps. After replacing the battery, problem was gone.

So, i hope this helps people with same issue.


Cheers!
