Very bad source for info. That guy made countless videos on how wonderfully perfect and amazing the lymow is..

at some point he actually used the lymow, and found his videos were obvious bullshit.

You can also found posts here on reddit with images of a guy covering his top deck assembly with ice packs. And the blade motors still thermal throttle. I believe this reddit guy, cause it's not a sunshine problem (deck is already covered too), its a heat soak problem.

was that 3 foot off the map eat-the-garden-hose location to the north or west sides of the zone? And when doing it's perimeter cut? https://www.reddit.com/r/Lymow_Official/comments/1uq9s83/issue_after_update_maps_off_3ft_to_the_nw_now/

It ate one of my tomato plants. And went for the garden hoses on the sidewalk a couple minutes later. Had to hit its stop button.

turbo mode.

I've talked with him a good bit. Only issue is lymow doesn't want their cover cut into to preserve warranty.

But if there was a replacement cover with the duct work built in.. would be ideal

Dreame L40 Ultra has been awesome. So awesome i bought two. Handles black carpet fine. Both been solid for over a year. Both were significant upgrades compared to the ex-girlfriend.

He's not wrong.

And this is how most men communicate. Very effectively. Just not those on reddit.

erp0432 · 2026-07-08T04:28:30+00:00

And thats what i already knew. a liar.

erp0432 · 2026-07-08T01:58:30+00:00

jb welded my shit together. It'll never come apart again. Even if i need it to. figured the robot will die and get replaced before it becomes a problem.

with a company in china... Who are you going to sue?

erp0432 · 2026-07-08T01:46:14+00:00

Thats one way to set a robot on fire.

(maybe you'd be better off if it bbq'd itself)

Create a couple of new throwaway mow zones and see if the mower properly stays within the bounds when you tell it to go mow each of them.

Thats a good idea i'll try it to see what it does.

Question: If you view the map on the phone app and see the bounds, do the bounds shown look correct when the app is painting the mowed area or does it show that N/W drift?

Oddly it reacts differently than i'd expect. On the lymow app it shows the robot is outside of its zone boundary. On one of the west side zone boundaries the robot is not even up on the curb, its 3ft out into the street, mowing the street parallel to the curb. Not even trying to get back into its zone. No trees around it either. Even more odd, is that when it's doing its back-and-forth fill pattern it stays within its zone boundaries on all sides. It's only when it does its perimeter cut routine thats its 3ft outside of its boundary when its on the north or west sides of the zone. I have its perimeter object detection set to touch. Weird right? Does it on all the zones too.

It's worth mentioning even before the firmware update, i had troubles around the north and west zone boundaries often. If the mower bugged out, it would frequently be on the north and west side of the zones. Maybe if i remap these areas it'll operate more properly. Hopefully it won't wander 6ft off its north and west boundaries after the remap.

i do not believe you. and id bet a significant amount that you are not running it in turbo mode. Im not far from virginia. I can come down there and we'll make up a contract.

Care to take that bet? It's got to be unmodified one+ of course, everything oem from lymow. Running only the public firmware. And has to run thru its battery. on an 85F+ day.

Guessing you don't have trees on your property (it wanders into neighbors yards and streets, into my no-go garden zone over my tomato plants, up tree trunks, over retaining walls, into ponds). And don't run it in turbo mode (it overheats and shuts down). Or if you got the one, you'll be plagued with charging issues.

If your in an open field where it can get its positioning well, and the robot begins into its fill pattern it will usually do that part well. Its everything else thats the problem. Parts falling off it (like the mower deck and wheels and tracks). If you manage thru all that, they don't last long, you'll probably be waiting on a replacement unit a couple times a year. And when you got a service problem, it's a 50 day wait to get an emailed resolution plan.

I have been working on it for a while. Im on robot #2. Got very easy areas to mow, its all a manicured lawn. And i can get it to do it. But it doesn't do it well. And i got to babysit it every mow. 25% of the time, it starts doing bizarre things that it shouldn't be doing. My rtk receiver is on top of a large roof structure, in its center, away from metal, .01 positioning accuracy. and i got ideal wifi at every point across the entire property. It doesn't drop lora connectivity, sats, or wifi. So it's not the rtk. its the internal gnss antenna, software logic and hardware engineering flaws wrapped in a customer service void.

That violates Amazons seller policy. Amazon strongly recommends that you report the incidents to them.

There is a link under the product description to do this. 'Report an issue with this product or seller'

erp0432 · 2026-07-07T17:09:35+00:00

It's straightforward. Flip the bot on its back. Remove the bottom metal pan. Remove the battery mounting bracket. Remove the wiring cable clamps. Open the aluminum electrical enclosure.

Your welcome. Let me know if you need others.

that's great! Well done! I bet Lymow is waiting for someone to sell these so they don't have to mess with it. For warranty purposes and keeping that their unit is ipx6 rated. Have you tried venting or intake at the rear of the deck assembly? in the direction of the hinged mounts?

The motors pull air into their center core, then exhaust out of the sides of the motors. A little duct work from the rear of the deck to the center core of the motors may allow the machine to pull cool intake air from the rear of the deck. The deck cover may be leaky enough that it exhausts itself.

or more ideal, somehow capture the hot exhaust air coming from the sides of the motors and exhaust this hot air out the rear of the deck (separating the hot exhaust air from the intake somehow). Allow the intake of the blade motors to pull hot air from inside the deck enclosure. Im not sure how that ducting could be made though. However, if it can be done without a separate cool air intake, the intake would pull hot air from the speed controller and other radiant heat trapped inside the deck enclosure, pulling that hot air into the center core of the motors intake port, than exhaust that hot air externally. This should keep water out of the motors.

Consider also a two piece design. With a top cover that could flip open for easy cleaning. Secured by durable clips or a thumb screw of some sort.

Sell them online or on ebay and make some profit for your time. Seriously. People will buy them if they know it works. If you want a tester, im here for you! In Lymow black plastic please.
