My Lymow One warranty experience — April 23 to August 18, 2026

On April 23, 2026, I emailed Lymow to report that my charging contacts had gotten hot enough to smolder and possibly burn the grass clippings on the underside of the robot.

May 5 — First response from Lymow support, 12 days later, with basic troubleshooting steps.
May 12 — Approved for a replacement unit. I was told the Lymow One was out of stock, but that I could upgrade to the Lymow One Plus for an additional fee.
May 21 — After multiple back-and-forths with support, I elected to wait for a Lymow One so my warranty would be honored without paying an additional fee. I was told a replacement would be available in approximately 2–3 months. Lymow support confirmed that timeline again in an email dated May 22.
July 20 — I received another email asking if I wanted to upgrade to the One Plus for an additional fee, this time lower than the first offer. I again elected to wait for the Lymow One, based on the number of issues I've seen reported with the One Plus. That same email stated the replacement was still approximately 2–3 months out. I replied the same day asking why it was still 2–3 months out when the original 2–3 month window had just come and gone, and I included their May 22 email stating the same wait time.
July 21 — The next day, I received an email stating: "I am pleased to inform you that we have just received a new shipment of Lymow One units at our warehouse. That means we can now proceed with your warranty replacement without the long wait." I sent my address the same day. Lymow support then told me I would need to pay an $800 deposit to ensure the defective unit was returned. I declined to send $800 and asked what other options were available. Their solution was to remotely brick my current unit and then ship the replacement. I waited a couple of days, made sure my yard was freshly mowed, and then replied that I was agreeable to that.
August 13 — With my mower already disabled and removed from the app, I followed up asking for an update.
August 14 — I received a FedEx shipping label.
August 18 — The replacement arrived. It is very clearly used and damaged out of the box. The deck lift motor struggles to lift the deck, there are signs of wear on the tracks, and there are scratches on the body of the unit.

That's roughly four months from reporting a potential burn hazard, two offers to pay for an upgrade instead, a working mower disabled at their direction, weeks without any way to cut my grass, and a used, damaged unit delivered as the warranty replacement.

Lymow needs to make this right. This level of service is unacceptable for a warranty claim on a safety issue, and I'd expect any company standing behind its product to send a customer a new, undamaged unit — not one in worse cosmetic and mechanical condition than the one it replaced.

Trying to remove the Lymow One Plus bumper but running into this which isn't the advertised Phillips head. Any idea how to remove this? Iv tried an Allen tool, etc with no success. Getting the e44 error now that it's humid and grass is damp. Mower works fine in manual but won't move in auto due to the e44. When I checked the Diagnostic menu, it showed both were being pressed.

I’m not sure if others are seeing this, but the mower is skipping areas inside the boundary yet saying mowing is 100% complete. It makes no sense. The area just above the mower on the left is the area in the picture. When I took the picture it’s very clear that it missed/hadn’t done the area yet. But it went on to “complete” the yard and go back to its dock at 42% charged. When I pulled up the history it says 90% mowed and shows and even different coverage. This is beyond frustrating. This thing misses this area every single cut. How do I get this to work? I even changed it from Smart to Collision because I saw someone said that might help. I had it recut the same yard and it missed the same area again. Accuracy is between .01 and .02 the entire cut. Why is this happening? I bought this thing to set and forget and I feel like I spend hours every cut babysitting it. Thanks!

Today’s mowing was frustrating as S*&#. I have had some good runs lately but today was skipped patches, a run right through the middle of the mowed lawn to get to a small area it missed, and the overlap was crappy. I’ll spare you the photos. Looks like mohawk haircuts on my lawn. I decided to mow the rest of the zones manually via the app and that’s when I really got in a bad mood.

In the video you can see the mower overreacting or responding late to commands so every time I tried to mow an edge or even start a straight line the mower over compensated so I was constantly back and forth. When I finally finished, the mower was put in "time out" with a battery pull. We’ll see how it behaves next time. It’s like wondering if your favorite musician is going to show up for their show drunk or not.

Now that this post is way too long, has anyone else experienced this? If you have, was there ever a definitive fix that you found or is it just another One Plus issue to live with? It is exhausting to monitor this each and every time. Thanks. Oh, thought I would add that accuracy was 0.008 the whole time.

I see Lymow has released the production kit for the 1+ cooling solution. I was one of the Betas testing with the 3D printed design. I can say that my testing was successful. I had my unit parked in the sun in the middle of the hottest part of the day for an hour, per the testing protocol, and then it ran my unit. Starting deck hood temp was 141.3 F. My grass was long and my RPMs were Power. No blade stoppage or derate. I did a multihour run and checked the hood temp every 30 min. Highest recorded temp was 143.6 F.

Installation was a little tricky, but i know many of us gave suggestions to simplify it, and it sounds like Lymow listened to us.

If you have overheating problems and haven't ordered the free kit yet, I would do it.

Today my Lymow was mowing without issue when I got the slipping detected alert. After inspection it seems as though the bolts came out or broke off of the rear left wheel. Had anyone experienced this? It literally cannot function now. I bought this about a year ago and got delivery about 11 months ago. I’ve used it several days every week all season. How TF does this happen?

After a two month process, Lymow made everything right. It really is the best mower available, when it is working. I have an Anthbot that does my back yard. It is adequate, but not nearly as good as the Lymow. That's why it is in the back yard.

Purchased back in May and just started having fits and RTK offline “Not Ready”… water seal (rubber ring) was not installed properly from factory. Thing was filled with water. I know I’ve seen previous posts about sealing these and now see I should have checked it before mounting it up at the peak of my 2-story house…

UPDATE: up and running! Dried it out. Cleaned the board and usb-c port with 90% isopropyl. Looks like the board has some water proofing over the components but I think the USB-C port was causing a short? (that’s where most of my water was pooled)
RTK status: Fixed, Location Precision 0.011m, Base Station: Online.

I spotted the Lymow forum's call for testers of the 3D printe moter cooling fan it and signed up. The kit arrived within a week. Install took longer than the video made it look. The guide covered the steps, but I hit a gotcha: the duct runs under the heatsink, so you pull the heatsink off, fit the duct, then refit the heatsink.

Mine arrived last week and I ordered the first week of April. I was charged in April because it hadn't been backordered yet but whatever. I got a shipping notification when it was mailed.

The cable gets plugged into the charger where the dock plugs in. This worked for me (10A charger), and I charged the battery from about 25% to full which read as 99% on the mower display and in the app. The charger light turns from red to green when the battery is done charging.

I didn't realize until then that the charger gets hot. It was 130 degrees from a temperature gun but the battery was 82 like the air temp in the garage.

My 1+ hadn't been charging from the dock at the time. This cable was convenient because I was sharpening the blades while it was charging. The problem was most likely the dock rain sensor because when I turned on Rainy Mowing, the charging from the dock worked again.

Guys,

I've been brainstorming with a friend of mine (Juha M3) on ways to fix the Lymow One Plus from overheating WITHOUT voiding your warranty. He came up with the concept of utilizing a "scoop" as a way to suck in cold air and cool the motor blades like a chimney, while the air can leave freely through the back as your mower drives along. There is no drilling involved, plus I found a way around some of the limitations of the original design to utilize a 12x16" piece of white acrylic, double-sided interlocking tape, and magnetic cell phone mounts to secure the "scoop".

My Lymow is currently broken and won't charge,, but Lymow sent me a new battery last week which still wouldn't charge, but did come with about 75% charge from the factory...so I figured why not put this to the test and see if it truly works. Side note, its REALLY DISAPPOINTING my mower has not been working for 5+ weeks at this point. Customer Service has got to improve. Pathetic getting a response one time every 24 hours if you are luckly, sometimes waiting days to hear back.

Results were far better than exepcted, about 200% better runtime with the same conditions as my prior video (see Lymow Fails To Cut Tall Grass)...That video it was about 88 degrees outside and humid, the mower ran for about 14 mins before it cut out, this time around it ran for ~28 mins then kicked down to eco blade speed for the remainder of the cut

I normally wouldn't cut at 3 ft/second and turbo blade speed, but I was trying my best to get the mower to stop working and replicate the prior conditions. On a typical day, this should keep your mower running at a slower cut speed and travel speed without any issues.

Again, big shoutout to JuhaM3 for helping pioneer this idea thousands of miles away and I really wish I could use my mower now, but sadly...I had to send it back for a replacement.

Let me know if you have any questions. As soon as I get my replacement mower i'll likley be churning out more videos with this Chimney Mod!
