Suddenly Powers Down

I need to express some serious frustration with my Yarbo right now.

Over the last couple of months, reliability has gone downhill dramatically. Last year, during roughly 8 months of use, I had relatively few issues. In just the last 2 months alone, I’ve experienced more problems than I did during the entire previous season.

The newest issue is the most concerning yet: the unit now suddenly powers off in the middle of cutting. Before anyone says “low battery,” the battery is NOT the issue. The battery level appears completely fine when this happens.

What’s especially troubling is that I recently saw a Facebook post where at least 5 or 6 other owners reported the exact same thing suddenly starting to happen to them as well. Oddly, that post now appears to have been removed or taken down.

I have already submitted a support ticket, but so far the responses have been generic and unhelpful. At this point, customers deserve acknowledgment that there may be a broader issue occurring instead of being treated like these are isolated incidents.

I invested in Yarbo because I believed in the product and the company. Right now, I’m losing confidence quickly. I hope Yarbo starts communicating transparently and addressing these growing reliability problems before more customers become frustrated.

They are definitely aware of it and I’m sure trying to figure out the root cause. Let’s hope this new firmware hotfix resolves it magically for you. It’s definitely not one of the stated fixes.

I hope you are right

I think this just happened to me. My Yarbo is dead in the middle of my yard. Woke up at 3am to check on it, and I had an error about being stuck and it was offline. Went out and found it in the middle of the yard where it was cutting and dead. Got plug in charger and plugged it in with a battery inverter, it is only drawing less than 300 watts. Charger is green before and plug it in, and when plugged into rover it turns red, but only 300 watts of draw.

Plugged battery in and unplugged no go, held reboot button, no go. First time I ever cut grass at night and this happens.

Oh no! Maybe leave the battery disconnected for a bit so things can reset.

Hope it’s not a critical failure.

I called support at 4am, they do answer. I walked back out and held button for probably 20 seconds and it came back on. It was totally dead, like out of battery. Just incase this happens to anyone the wired charger only draws 300 watts.

They can’t explain what happened. It was not stuck, it just stopped in the middle of the area it was cutting right in the middle of it’s cutting row, so it never even tried to charge. Don’t know what to think of stuck errors I had.

So now here I am waiting for it to get above 15 percent to see if I can drive it back to the charger.

Totally odd never had this issue. Hope it wasn’t related to trimmer use today?

I have it set to recharge at 15 percent, and I have low battery protection turned on. Support said maybe with a large yard it died before getting to charger, but it is in the middle of row right where it was cutting, so it did not die driving back to charger area.

Odd one for sure. Crappy thing is I was trying to get grass cut as a ton of rain is coming, this am, so not sure I can even test out if it works or not.

I am going back to bed, after I get this thing on charging pad.

This is why I have two Yarbos…I can pull the battery out of the 2nd one to get the first one going. Was initially going to purchase a 2nd battery but realized if the first isn’t functioning I could still have a backup. 2nd one was purchased from the refurbished Yarbo store. Good luck!

Glad to hear your Yarbo is back up and running, but I don’t like the response you got from Support.

Hopefully they come up with a better explanation about what caused your Yarbo to abruptly die like that.

Yeah I am not sure why they don’t pull the logs and look. That was a stupid explanation by him on what happened. I am out there at 4am and can see it just died while cutting. I explained it perfectly, he then told me to keep a closer eye on it to see if it happens again.

I hate when we get obviously incorrect answers from Support. It’s like they don’t take the time/effort to really analyze the problem or the data.

I’m betting your BMS isn’t properly calibrated to the actual SOC. I’d pull the battery cable for 4 hours to force a recalibration.

Could be, but it really should be able to keep calibrated as I use my mower at least every other day and run it from 100% to below 15% all the time. I would think it would be more likely if I kept using it at a higher range, and never closer to full spectrum. But anything is possible with yarbo.

Yep. Certainly shouldn’t be happening.

These are modern times. Imagine if all of our phones, electric cars, power tools, etc occasionally needed a 4 hour battery disconnect to ‘reset the BMS’.

We’re sorry for the inconvenience and frustration this has caused.

I’ve checked your support ticket, and your case has already been escalated to our Field Service Engineer team for further investigation.

We also appreciate the discussion shared here. We understand this does not appear to be an isolated case, and it is something that requires deeper investigation and attention from our team.
