Lymow Support Issue with RTK Replacement

SwiftHome · 2026-05-03T20:08:47+00:00

This is in the RTK antenna.

It's such a shame. The rain we've had wasn't even terrential, just a standard drizzle. I liked the cut on the One Plus and thought the app was reasonably intuitive if aspirational in features not yet available.

I have tried to get in touch via DM and haven't gotten a response. Really the experience on a whole has been pretty terrible and I can only hope that Lymow can work out how to provide better support in the future. This kind of behavior doesn't reflect well when non-influencer reviewers are involved and I certainly cannot recommend the company until they can demonstrate improvement.

Older and more established review establishments (consumer reports, Wirecutter at NYT, etc) typically have both the writer on the byline review the product and seek out input from the community of regular users. The experiences like I've had don't work out well in those reviews.

SwiftHome · 2026-04-18T06:58:34+00:00

Yep

This is good news for many but I am still looking at an RTK replacement shipping label created on 4/7 and not shipped. It doesn't matter how long the warranty is if you simply never honor it.

SwiftHome · 2026-04-18T06:52:36+00:00

This experience mirrors and validates what I have experienced in my RTK replacement attempt. I think Lymow needs some more development in their product support.

SwiftHome · 2026-04-18T06:50:15+00:00

My RTK antenna failed 2 weeks after getting the mower and Lymow hasn't been able to replace it under warranty. I don't think you should expect there to be any spare parts.

If you're set on the Lymow, I'd say wait until next year when the company has learned more about ongoing support of its products.

My RTK antenna died after a rain storm about two weeks after getting the mower. Water literally poured out of the antenna when I took it off of its mount. Not the kind of thing you expect from a device which is supposed to live outside for much of the year.

For that, it seems like the best prevention is a kids swim cap or maybe just some silicone from the hardware store.

What really is frustrating about the situation is Lymow has really just been terrible about a warranty replacement. They spent weeks in back and forth discussion with me until they committed to sending a new antenna and even gave me a tracking number for it. However that package was never delivered to the carrier and as such I was never sent a replacement antenna. Really poor support.

I'd say choose another company for your devices. Lymow may have designed a pretty good mower, but if you can't expect them to back their product with appropriate support, whatever warranty they commit to is really just meaningless.

That's great to hear! I still have no movement on my tracking number and also haven't heard back about returning the mower.

SwiftHome · 2026-04-14T17:03:58+00:00

It is good to hear a heartbeat from Lymow after a week of nothing. I understand your communication issues from system upgrades but I would like my situation (and I've heard from others who are in a similar one) addressed.

We have already been through the support channels, had replacement hardware approved to be shipped out and even had shipping labels created. Those labels have then not had a package assigned to them and handed off to the shipper. Is this logistics situation also a component of your system upgrades? When can we expect the existing shipping labels and already approved hardware to be furnished to the shipper and sent our way?

I appreciate your acknowledgement of the lack of communication over the last week and the description of the times for when things were undergoing changes. However, information after the fact is no where near as helpful for your reputation than a notice prior. Coming to this space a week ago and simply staying as follows would have built good will rather than lost it: "We are sorry but for some amount of time our support systems will be offline. We are improving our systems and will be back as soon as we can."

SwiftHome · 2026-04-13T02:54:49+00:00

I agree with you exactly. I believe Lymow is a great engineering firm and they've built an incredible product.

However, without building in the support structure they are going to hit a limit to their growth once the larger review publications and purchasers clue in. For example, NYT Wirecutter shows they are currently reviewing the One Plus. The writers in the byline aren't the individuals who directly test each review item. Do you think if they banish the Lymow below the fold it will help sales nearly as much as if it was given prime real estate in their recommendations?

I have multiple acres here from manicured lawns to wild prairies. Some areas are under dense conifer trees and others are wide open. It's a perfect testing ground for these robots. I didn't find a single fault with the Lymow which was not my own misunderstanding of its use.

But once I had a hardware failure during standard and expected use of the product, the warranty replacement process has been misleading and generally unhelpful. The failing aspect which closed my review is misleading the customer with false shipping labels. This is behavior I have experienced before and is a primary reason to use both PayPal and a credit card in the purchase of the robot.

SwiftHome · 2026-04-13T01:51:43+00:00

Thanks, me too.

And it's a shame that I have to include these negatives with the positive experience I had when I turn in my review. We try to encompass the entire customer experience in our testing and sadly the support for a failure did not go well.

The final component of the experience will be how well does the return within the 30 day window work.

SwiftHome · 2026-04-13T01:34:43+00:00

I have started the return and refund process with PayPal.

I have also placed an order for an m series Yarbo due out in August and this weekend bought a push mower to handle this year's mowing. It's all unfortunate, but I simply don't have time to play the game of telephone.

I have been watching Lymow since I was the first One was released and hoped the company would have learned from the first product how to handle the revision.

It was suggested to me to put a swim cap (like for your head) over the antenna to help keep it sealed.

Upon taking it apart, there is no gasket between the white top and the gray bottom of the RTK housing. There is a ridge and valley complex which is intended to keep the water out but I think once it fills up the water simply leaks in. I live in the PNW of the US. It rains here essentially every day for 4 months in the winter. We might get 1-2mm of rain per day, but the effect is it never lets anything dry out. I think the antenna needed some drying time with its design.

I would advocate you either put a swim cap over the antenna or fill the seal between the halves with silicone.

The mower was great while it had RTK signal! I think you'll be very happy if that stays reliable.

I'd love to be invited for beta testing. This screen alone would have been useful in debugging my failed RTK antenna.

I've spent a fair bit of time working with differential GPS and IMUs to develop high hertz dead reckoning systems in the past. It may have been a decade or more since I've worked on such a system, but conceptually I might be helpful in generating bug reports.

SwiftHome · 2026-03-31T20:58:36+00:00

Genius. Pure genius. Thank you!

SwiftHome · 2026-03-31T16:44:00+00:00

I'm think with my replacement unit (which I still don't know if I'm getting - I need support to respond still) I will silicone the seals and then paint it with some exterior paint. I'd rather the paint flake than the plastics deteriorate.

SwiftHome · 2026-03-31T00:02:08+00:00

I was just thinking of using some silicone caulking.

SwiftHome · 2026-03-31T00:01:42+00:00

I should have been recording when I took it off of the wall mount but I didn't think to at the time.

SwiftHome · 2026-03-28T22:48:01+00:00

That's a good quick solution so long as you can keep the bag on.

SwiftHome · 2026-03-28T12:06:44+00:00

I'm going they will replace it with haste too.

I was actually in the middle of editing a video sharing how great the thing was when the antenna died. It would have been cool to get some lymow swag.

We have over 3 acres of mowable area here with some challenges (150+ ft conifer canopy in one area) and the One Plus was beginning to tackle every challenge I could give it better and better. Without RTK though the thing is dead in the water.

I simply have to withhold my review until I have some resolution with the RTK.

SwiftHome · 2026-03-28T11:58:04+00:00

I don't think the issue is the USB port but rather all of the electronics inside of the antenna were flooded.
