Segway i105N Robot Lawn Mower Perimeter Wire Free 1/8 Acre RTK+Vision Robotic Lawnmower, AI-Assisted Mapping, Virtual Boundary, APP Control, 58dB(A) Quite, Multi-Zone Management

EXTRA TIP: If you want to mount your antenna on top of a flat surface, and you don't need an extension cord, and you don't want to pay $50 for the official antenna extension kit, try searching Amazon for 'Light Wall and Ceiling Mount with 5/8" Stud and 1/4" Thread'. I happened to already have this item sitting around, and it fits the threads on the antenna perfectly. The only caveat is the that the square shape of the antenna doesn't align with the square base of the mount when fully screwed on. Just cosmetic issue, and in my case you can't even see the antenna without climbing a ladder. UPDATE 2: I am pretty well delighted with this product now. As I mentioned before, Navimow support recommended diabling camera-assisted positioning after my map deleted itself. But I decided to try mapping my yard one more time without disabling that feature, and this time it worked fine! The mower is doing a fantastic job of navigating my yard and I'm so happy I don't have to spend my weekends mowing anymore. There are just a couple of spots where it has trouble due to sloping/uneven ground, but Navimow support is also sending me a couple of free accessories as an apology for the bumpy experience I had initially. Hopefully the off-road tires will improve the unit's traction, but even if I have to hit those two spots manually with the weed whacker, that's not a big deal. I can also confirm that I've been able to map more than 600 square meters of lawn area on the i105N, so it seems they really did raise its map area limit to be the same as the i110N. A very welcome upgrade. I have a theory about what caused my map to disappear the first time. I could be completely wrong, but just in case it's helpful to anyone... When I was setting up the last couple of boundaries right before the map disappeared, I took some fairly long pauses to clear away debris from the edges of the lawn. I'm thinking maybe the camera-assisted positioning video keeps recording even when you aren't moving the unit, and so I ended up with some massive video files, and their sheer size caused the glitch that deleted my map. Sooo, if you want to be on the safe side, maybe try to make sure you get any prep work put of the way before you start mapping a boundary. Overall I think this is clearly the best value among GPS robo-mowers for anyone with a relatively small yard, especially now that it seems to support up to 1200 square meters of grass. If your lawn is closer to the upper end of that range, you might want to consider the i110N, which is still an excellent value compared to most other GPS mowers on the market. But even this i105N seems like it would have no problem covering that area as long as you don't mind it doing so over the course of two or three days. --- UPDATE 1: I've exchanged several emails with Navimow support now. They did a much better job of understanding my problem after that first reply. Unfortunately, they are unable to recover my map, and they have suggested that I try disabling camera-assisted positioning and re-mapping my yard. They seem to think there might be a hardware issue with my particular unit that is causing it to lose the map when processing the camera data. However, they have offered to compensate me for this frustration in a number of possible ways, including free accessories, and/or replacing my unit with an upgraded model to better accommodate the size of my yard. They also informed me that the coverage limit on the i105N (all units, not just mine) has been upgraded to 1200 square meters, the same as the i110N, which is very much appreciated. I've agreed to spend some more time testing my unit to see if disabling camera-assisted positioning fixes the disappearing map issue, and whether the unit is able to navigate my yard without that feature. (I'm somewhat doubtful, because my yard does have some areas with tree coverage, etc.) Then I will report back to support with the results and let them know what sort of compensation would be most helpful. This is all just theoretical for now, so I'm not changing my rating yet, but I will make sure to keep updating this review as the situation progresses. --- INITIAL REVIEW: I'm still holding out hope that this will work out for me, but the experience so far has been rough. Basic installation was relatively straightforward, although I find it irritating that a wall/roof mount for the antenna is a separate purchase, because that's clearly going to be the best option for most people. The real trouble started when I was mapping out my yard. First, I was a couple hours into the process when I decided to set up a "channel" from my lawn back to the dock. This is a requirement if the dock isn't within the mowing area itself. The app briefly and casually instructed me to drive the mower from the mowing area to the front of the dock. However, I drove the mower all the way onto the dock, and it immediately went into charging mode, which apparently deletes any unsaved map changes. So I lost everything I had done up to that point. I was steaming mad, but there was nothing to be done except start over. Seems incredibly silly to just delete the unsaved map without asking, and even sillier to not warn the user about this when explicitly instructing them to drive the mower to the dock during a mapping session. So I started over and eventually mapped out my whole property over the course of a couple days, pausing freauently this time to save my changes. Now, whenever you add a new mowing area to your map and then end the mapping session, the mower asks to return to the dock and process the "VisionFence" data it gathered during the mapping. So after my final edits, I allowed this to happen, and the mower spent the next hour or so processing the data. Well, when I came back and checked the app, my map was completely gone. No sign I ever even started one. Absolutely incredible. This time I reached out to Segway support via chat, and after some brief troubleshooting steps the agent informed me my ticket was being escalated and I should hear back via email within two days. I did not get any kind of automated email confirming that a ticket had been created, but another agent confirned this the following day. Today, two days later, I did get an email response, but it was completely unhelpful, offering instructions on how to get the map to save (which isn't the problem I'm having). In the meantime, I doscovered that after reinstalling the app, my map shows up again, but it disappears as soon as I pair the app with the mower. So I am hopeful that my map still exists somewhere and can be restored by tech support. I replied to the email with a screen recording of this and another explanation of my problem. Now I am waiting again. I will update this review as the situation progresses. The other extremely irritating aspect of this product is the arbitrary, software-imposed limitation on the area that can be mapped out for mowing. I did my best to estimate the size of my actual grass areas before ordering this model, but it appears I was off by a significant amount, so even if my map does get restored I might have to return the unit and order the 1/4 acre version for $300 more. No clue if I'll be able to transfer my map or if that will mean starting from scratch yet again. I get that they want to encourage people to buy the more expensive model, but they should allow the larger battery to speak for itself instead of imposing artificial limitations. This is only going to result in lots of mowers being returned when people discover they have more grass than they thought. Aside from all my complaints, I can say that the mower did work beautifully during the brief time I was able to test it out on part of my yard. There's a small section with an overhanging carport that seems to cause trouble with GPS reception, and for whatever reason the VisionFence is unable to compensate in that spot, but overall it shows a lot of promise. I'm still clinging to hope that these issues will be resolved and I'll finally be free from spending half of every weekend cutting grass.

If the sales information said the Segway Navimow i105 wouldn't work under trees, I didn't notice it. I have silver maple trees covering 90% of my yard not covered by my house, so when I read the installation guide, my heart sank. I found an online review that reported success with trees, so I decided to try and see. The installation guide consists of a bunch of steps, each explained by a single sentence is in a dozen languages, with cryptic symbols and drawings. I looked at it for a long time to try to figure out whether both the docking station and the antenna should be in the same place, and which one was pickier about seeing the sky. The user manual is available online (google navimow i series user manual), and it explains the numerous navigational redundancies that enable the Navimow to find its way under trees. But it did insist that I put the antenna in the 10% that has a clear view of the sky and the invisible GPS satellites up there. I first tried putting them both under the large silver maple in the front yard, but the app intervened, and when I thought I was mapping that yard for mowing, it was actually mapping for best satellite signal. I left the dock under the tree (still ~20 ft from the house) and relocated the antenna to the front edge of the tard next to the sidewalk where the signal was the strongest (another 20 ft from the dock). The extension wires that came with the Navimow were long enough, and the little plastic tent stakes pinned them to the yard where it would later mow without any damage. The antenna looks a little goofy out in front like that, but I was then able, using the steering function of the app on my iPhone, to map the perimeter of the Main front yard. I went slowly, stopping to switch between Standard, Ride-on and Assist mapping. The Assist mapping recognized the bricks around the gardens and zoomed around them accurately. The ride-on complained that it couldn't detect the junction between the yard and the sidewalks while mapping - but it recorded that mode for that segment anyhow, and later during mowing it worked perfectly. I was impressed that it kept track of everywhere it has mowed, and at the end, it went back to get the strips and spots that it had missed - probably because of the bumpy turf and tree roots that it managed to negotiate. I was able to map a second, third and forth area, with channels to them, and it then mowed them too. The Navimow has a couple of large conspicuous lights, and it beeps like R2D2 and talks. Besides being a challenge to understand, it seems to invite theft. Rather than ante up another $150 for the cell transmitter and a 4G subscription, I bought some Apple Air Tags that should work almost as well for less than half the money. Before spending $1k on the Navimow, I considered spending $700 on a battery mower I would have to push, or the Husqvarna that requires a wire around the perimeter. I also shopped for a lawncare service (guys who once mowed our ephemeral garden!). I chose the Navimow because Segway has been making robots for decades. The Navimow is an impressive computer navigation system atop a capable grass cutter, with a satisfying app. And it makes my yard look good while I do other home projects. It seems pricey, but it's a good value. I recommend it. Updates: After submitting the review above, I noticed that, although I ordered the i105, I actually received the i110. According to the Navimow website, the only difference is that the i110 battery is 2x that of the i105, and mows 1/4 acre (1000 m2) rather than 1/8 acre. My mowing area is only 141 m2, and mowing it, probably because of the slopes and roots, consumed 60% of the battery charge. This i110 has now mowed my little yard twice, each time from a full charge. It got stuck on a root once, and on a curb. I'll fill around the root with some soil, and hope that the i110's AI will figure out how to not drive off the curb. I also found out that I might be able to use only one of the two antenna pole extension pipes, and I might try that so it looks a little less goofy if it works as well at half height. But since it will require re-mapping all four of the areas that comprise my yard, plus the keep-out around a tree, I might put that off until fall. Stay tuned.

This actually works well. Setting it up for satellite signal reception is one challenge; if your yard does not have a clear view of the sky, then it's a no-go. But I got satellites in view and a good signal, so that was fine (I have a lot of trees and buildings near so it was a small challenge). Then the training for the boundaries was a bit tricky, as I had to walk with the mover, remotely controlling it from the phone. But in the end it was fine. Had to do two corrections to the map, and after that the mover works 100% on its own, never gets stuck! Battery lasts about an hour and maybe an hour and a half. Mows fine in my backyard on one charge. It is weather-aware; lots of settings in the app. Really great and helpful app. It mows my front yard too. I have to hand-carry the mower there, but then it does it on its own; I just carry it back to my backyard where the charging dock is. You gotta buy the garage too so it's protected from weather. I do recommend this for small yards if you have a clear view of the sky. If the configuration had been a bit easier, I would have gotten 5 stars.

Navimow i105n This is truly a game changer. Absolutely worth the investment and works amazing right out the box. Take your time picking a good location for antenna and charging station and you'll be good to go. Do not stress if it misses things, it seems to catch them in the next go. If problem persists then it may be Antenna placement or poor mapping. It is super quiet to the point that I thought it was broken. Mapping the yard was a breeze and the APP is very well thought out. I love the fact that you can remote control it like an RC car. It is not designed to mow overgrown grass, but I did it anyway and saw good results. This is designed to maintain your lawn so it doesn't ever get overgrown. You will still have to weed eat the edges, but it saves so much time. If I had to do setup again, I would have mowed it first before using to better map the area. I enjoyed having a beer and watching it instead of sweating and getting sunburnt. Only con is the garage for it is ridiculously expensive and quite frankly should have been included in the original purchase. You can create your own far cheaper. I am still giving it 5 stars just because its probably the best quality of life purchase I have ever made. Just buy it already. Segway knocked it out of the park with this one. You have a customer for life.

Update. Originally this was a 5 star review. In December I bought a house and we moved our lawn bot to the new house and now it doesnt see satellitez. So i contacted segwayy. An.d after 3 ho9urs trying to fo d a number I texted and got someone on the line. They had me moving the antenna all over yard. Nnot super easy not hard just a pain. Then pictures. Etc etc. Then they said oh we will submit to engelineering and get back with you. That was three days ago and nothing. So if they ever get back with me I'll return to previous 5 star review depending on response but so if you don't know. No antenna no gps satellite . No lawn mower. So i have a1400 lawn ornament. In my world warranty is a year. I used this lawn bot from August to December that's 4 months then it sat there and yes I'm less than happy with segway response and plan to do a google review. As well. My previous review is below. Just heard customer service is poor So I'm busy answering I mean busy. Kids are in college so not much help there. It's florida so mowing is risking heat exhaustion every time and in summer grass grows so fast. I got this to help lighten the load. It took the adult child to set up the perimeter as he games and driving it around the boarder proved beyond my controller talent lol. But today I decided to mow the law so I propped up my chair by the windows and set it out to mow. Easy peasy. I'll upload video when I figure out how but it's a must. I leave it unattended in our back yard as it's fenced but cars literally slow down to watch it in the front lawn. Game changer. So if you're like me nurse full time full time grad student and full time mom this is a must have. Best grand I ever spent and as I get older will be invaluable and save money as I don't need to hire it done. !!! Note to buyer get the extra module so it doesn't need your wifi. It's an extra 140 but also worth it plus it enables antitheft
