Based on the Yarbo info earlier, the trimmer line feed is designed to operate automatically (Auto Line Feed) rather than through a user-defined frequency setting in the app. The system was suppose to automatically maintain the string at the optimal length. BUT now I see “Line Feed Frequency: 5 min” by default and there is no auto option. Does this mean the line will be fed every 5 minutes and cuts to size required whether it is needed or not ? and also if the line is needed to be fed before 5 mins then the areas trimmer goes through without the line fed will be missed. @Yarbo whats the deal here. Are we seeing another promise missed?
It automatically feeds it at the specified interval. If it detects a line feed error from being too short it will also stop and start the trimmer again and advance the line simultaneously, a couple of times if needed. If the error doesn’t clear then it will pause the plan and wait for user intervention. You can choose to go and tug on the line to try and resolve the error or disable the trimmer in working preferences to continue with your mowing plan if you aren’t home. Could also toggle the trimmer manually a bunch remotely too and see if the error clears.
It seems to feed based on a set interval rather than need, which doesn’t feel truly ‘automatic.’ Also, how does the unit detect if the line is too short? Finally, is there a way to use the trimmer for just edging/trimming if I’ve already finished mowing and run out of line.
I’m guessing through monitoring motor RPM’s or something like that. No exactly sure how. If you’ve run out of line, you would need to install more. Then you could use the trimmer manually or send it back out to “mow” again and when it’s done with the perimeter lap (if you used the trim edge feature) then just cancel the plan. If you created a memory path, you just create a work plan with the memory paths you want executed in it and then execute that plan.
Thanks for the reply. If what you are saying is true then why we need “Line Feed Frequency” in the app ?
I think for now, this is how it works best. Over time, they may find ways to fine tune it so the frequency is less frequent or not needed at all. That can only happen with lots of real world data across many differing units, terrains, properties, etc.
that’s how it is
It’s raining here now, and I can’t do any further tests. However, the way it was designed, with manual height adjustment, is problematic for maintaining a precise cut on uneven terrain or slopes. An automatic height-maintenance system like the lawnmower should have been designed. It can sometimes touch the ground, and the lawnmower drags it back and forth. As for the line, I’ll do more tests as soon as the weather permits, because I think the output time can easily be increased beyond 5 minutes.
thanks everyone for replying. I would like @Yarbo to respond since it is one thing they consistently advertise as a feature in trimmer module. Yarbo need to clarify about this setting in the app.
Yes, that’s one of the things we recommended in our testing but not feasible without a complete redesign. I personally would like to see it fold up and out of the way when not in use, automatically.
It would be nice if it had an automatic axis that comes out and back in like the floor cleaning rollers on home robots.
I understand your point, but what you’re saying is that this was, once again, misleading advertising. If you search “line feed” on this forum, you’ll find an advertisement post that specifically states “Auto Line Feed.” I understand you want to defend them, but constructive criticism does not diminish innovation — it encourages companies to make responsible promises and set accurate expectations.
For that particular comment you are replying to I was referring to the following the contour of the ground @Gabriele was mentioning. For the line feed, I too was taken aback by the line feed frequency. My initial concern was that it was going to be wasting a ton of line. In almost a year (and I don’t use it every mow, maybe once a month) I have yet to replace the factory supplied spool. While I am not defending them, I do appreciate simplicity and the design is very simple and that makes it more robust. Less things to go wrong (generally). It does automatically feed out the line. It does not detect and feed out only what is needed. But neither does my hand trimmer either. You bump it on the ground until you feed out enough line that it cuts on the cutting blade and move on trimming. Simple, yet effective. Should also note that most trimmers of this type of design (like the ones for tractors) have long fixed length and thick line that you insert and have to replace fairly often. That would certainly be a pain.
I do believe the potential for capability exists that one day in software they could possibly achieve this only feed out enough as needed. Whether or not they can do that with this hardware or the next gen remains to be seen I guess. I do think there are still design changes that are needed for this to be 100% automated in every persons yard and terrain. I think this design works well in flat even terrain trimming along fence lines. Anything that can slip underneath the wheel is going to potentially cause some line feed errors. Right now, if the string can’t be flung out through centrifugal force alone, it requires manual intervention, unfortunately. Still a good first gen product. The software certainly needs work and I think it will get there.
I would rate the trimmer a 3 out of 10. Trimmer design is ok, but the rover is not smart enough, but maybe when they turn on the AI that the marketing team knows all about it will be better.
I wish the big circle-ring was smaller in diameter so the string would make it out to edge of the ring. Right now it is short and leaves grass, and as the string wears it leaves more.
That about sums up the reasons I haven’t pulled the trigger yet. The trimmer needs a way to follow the ground like a gauge wheel or TOF sensor, etc, and a way to swing out of the way, etc.
mine stretches enough…are you sure it won’t wear out quickly and do you need to reduce the number of minutes the thread is extended more?
I did not have much time to mess with it yesterday as we have a ton of rain coming today, tomorrow, and tuesday am. I will look at it more mid week or so.
As Bryan mentioned above, the trimmer will automatically feed the line based on the line feed frequency you have set in the app.
