I just received an e-mail about my current Yarbo issue (this will now be my 3rd core in less than 30 days). Yesterday after my mower finished mowing my front yard it returned to its base and charged. Then, when I sent it remotely to mow my backyard I got a notification that the blade height couldn’t be reached and I needed to clean the mower deck. When I got home I cleaned the deck and tried to send it out to mow the backyard, when I did I got the error B010.
I submitted a ticket and am now being told this…
“Our backend system includes a monitoring mechanism that triggers an alert when the current on the power board exceeds 5A.
This feature is designed to protect the machine and proactively detect potential issues.”
I am being told that a replacement core is now being shipped to me.
I asked a follow up question about if this is going to be common occurrence. If every time grass clumps under the mower deck and the blades cannot change height I am going to need to get a new core, I feel this is a design issue. I am now in a place where I am going to have to mow my yard manually (what I am trying to avoid by buying the Yarbo to begin with) while I wait on my replacement core. This defeats the point of getting the unit.
I wanted to see if anyone else is having similar issues where they are spending more time waiting on replacement cores than they are mowing their yard.
No this isn’t common and you shouldn’t have to be dealing with this. Especially after 3 cores. Hopefully third time is the charm.
But - make sure you do not hot swap the module. Always power down the core using the shutdown under safety settings before connecting and disconnecting modules. I’ve seen reports of people with this error because they are doing hot swaps. Pulling the battery cable usually clears the issue and error. You could try that and see if it clears the error and you can mow in the interim. If the error comes back, I’d stop using it for sure. I believe it’s a little sensitive. Just know that it’s a risk that the board may short out if it truly is a power board issue. Definitely visually inspect the power board for any signs of bubbles or burn marks or other damage before proceeding if that’s what you decide.

I have a zoom meeting scheduled for Sunday night. Maybe the tech will have me pull the battery cable. I’m frustrated because when the thing works it has been doing a good job. But if I need a new core every 3 weeks I’ll need an extra one always on hand just to keep cycling them on the mowing.

Well, 3rd time was not the charm. The newest Yarbo is now having camera issues and only the front camera works. I have been told (after 9 days of back and forth with support since each reply takes 24+ hours to get) that a fuse has gone bad and that I will need YET ANOTHER new core. This will be core #5.
The TERRIBLE truth is I like how it works… WHEN IT WORKS… I really want it to keep going, but the reliability of this system is near 0 in my eyes.
wow, I am sorry to hear that. That really sucks. Is the fuse not user serviceable? Seems much easier than sending a core. I don’t recall all your issues, but maybe it’s a power issue. Have they considered a replacement battery as well? Maybe a bad battery or something like that is affecting the cores.
Nope… see reply from Yarbo support below. They cannot replace it individually (I asked if I could… I don’t want to return ANOTHER ONE) and they want to do a ‘comprehensive study’.
I just posted a new thread in the Warranty section (waiting for moderator approval) where I list the 4 things that have caused new cores.
If this was a car it would be refunded via lemon laws 
sigh, so much potential… so many issues.
That’s a bummer, but I truly appreciate that they are analyzing these issues and correcting them. I’m pretty happy with my 2 units. Sure, there are some software bugs and some inefficiencies in the path planning, but those will get fixed. It saves me a ton of time and my lawn has never been this well maintained. I hate mowing the lawn and Yarbo has made that a joy for me. I can deal with some of the manual touch ups because of the safety buffers and other nuances that you have to work around. It’s manageable.
Hopefully this time they get you a unit with all of these corrections they’ve already addressed. I am impressed how quickly they move on addressing these issues in future production runs. Maybe @Yarbo-Forum might be able to have some influence here?
I’m really sorry to hear about the ongoing issues with the multiple replacements. We completely understand your frustration, especially with the long wait times for support. Please know that this is a rare situation, and we’re committed to addressing any problems you encounter. We’re hopeful that the new core will lead to a smoother experience. We’re also continuously working on improving the system to provide a better overall experience. Thank you for your patience, and we’re here to support you throughout this process.
