Review: Great customer support, fantastic value despite some hiccups - 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 desertcart 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.
Review: Time mapping lawn pays off BIG TIME - I received my Navimow i105N on May 8, 2024. I have now used it continuously since then up until today, June 20, 2024. I estimate this has saved me at least 7 walk-behind mowings with my Ryobi self-propelled mower, which BTW I have loved. I am going to use the descriptor word "mow" through-out my review but you would better understand the work of the Navimow as a trimmer rather than a mower. Once you have your lawn mowed to the height you desire, you can easily dial in the height you want your Navimow to keep your lawn trimmed to. It can be adjusted in increments of .04", from 1.6" to 3.6", which suits me fine. BTW I use my Navimow everyday except on rain days. In this regard my lawn looks freshly mowed every day! I allow it to mow from noon to 7:15 PM, which I have observed is more than enough time to do my entire lawn and also avoid the morning dew and the 20 minute watering I do on my lawn every other day which ends by 7:20 AM on those watering days. I am a 78 year old male living at 40 degrees latitude, which has very hot July and August temperatures, and even now in June. I just don't want to find a cool time of the day to mow, which I typically can't find, to keep the lawn nicely mowed. So, my motivation to use an autonomous mower, whatever the brand, was to stay out of the sun and the heat. So far, I have been able to do that. And, I didn't want one that required putting a wire around my yard. I read some of the 1 & 2 star reviews and could understand the points being made, but in my experience all of their frustrations are resolvable by just taking the time to set up the map for your yard properly. For example, when you come to a curb or a separation of the lawn to a hard service, such as my concrete patio, you should put the "edging" setting to "ride-on." This allows the Navimow to crest the separation, i.e. curb, and continue moving over that portion of the lawn, giving a better trim to that boundary separation. (May I humbly suggest that you watch the videos showing you how to set up a map. Most of those videos are available on YouTube, so you don't have to purchase this first to get access to those instrucions.) Also, the instruction forewarn that you will still need to trim and edge the boundary of your lawn. I use a worx 20v edger/mower to do a fine tuning of the grass height at the perimeter edges of my lawn. So once or twice a week depending on how fast my grass is growing I do a quick trim (approximately 20 minutes around the boundary perimeter of my lawn. I must admit I didn't know that the Navimow is hard programmed not to allow a mapping of more than 500m. My lawn map is 3773ft squared as per the Navimow mapping feature, which appears to fall within the programmed limits for my Navimow. With the battery in my Navimow, it will mow for about 90-95 minutes or until the charge on the battery falls below 15%, then return to the charging station for about 65-70 minutes to get up to 95% of a charge. (BTW it's return to the charging is a sight to behold. I almost feel like there is a "little man" inside the mower guiding it to slide right into the charging port on the charger. I was very impressed with how well it finds the charging station no matter where it is on my lawn when it needs to be recharged.) For the area of my mapped lawn, it takes 2 1/2 cycles to completely mow my lawn. (Also, you have to watch the map on your smart phone as it shows you what it has mowed to really be impressed with how well it keeps track of where it is doing its thing on your lawn.) Forgive me for pasting in this portion of the manufacturer's write-up on the accuracy of the Navimow's use of GPS to know it's position on your lawn, but I attest that it is a statement I could stand by: "RTK+Vision, Fit into Every Garden: Lawn covered by trees? Narrow corridor? However complicated your garden layout is, enhanced EFLS 2.0 got you covered. Customized RTK technology with Vision enhancement provides stable centimetre-level positioning to handle an incredibly diverse range of lawn layouts. Even when it’s under the trees or in a narrow corridor, Navimow still works perfectly with accurate navigation." Now, the lack of a Navimow Access module which allows for theft protection is clearly stated as not included with this model. I believe it is included with the next higher model. If my understanding of the Navimow Access' functionality is correct, it will allow an even more accurate and stable mapping using a cellular signal network, with the first year free of cellular fees but not necessarily after that first year of use. While I have two very tall trees around my yard, the GNSS antenna has successfully found the GPS satellite signals and kept my Navimow within the mapped boundaries. Regarding the Navimow getting stuck, of all the negative comments this is the one I find is completely the opposite of my experience. I have been impressed watching the Navimow get out of a rut in my yard or climbing from a hard surface up and onto the 3" height of my lawn. At first, I got impatient and either picked up the Navimow or gave it a shove from behind to move it along. That is the wrong thing to do IMHO. Give it time. I have had neighbors watch my Navimow work itself out of a stuck position and found it very impressive that whoever wrote the program, first, gave it the mechanical sense to know it was stuck, and, second, programmed in several back and forth and sideways maneuvers to unstick it. It really has to find a "hole" to become totally stuck. That is where good mapping and setting off-limit islands makes a big difference in having a frustration free "mowing." One further suggestion on helping your Navimow from becoming stuck is by setting the mowing direction options for your Mapped Zones for your lawn. I find the diagonal directions don't work well for me. I like the orthogonal directions, such as straight back and forth, or 90 degrees to that direction. One further aside, I had backed the Heisenberg all-in-one robot mower on Kickstarter. As a backer if the development and manufacturing campaign for that mower had been successful, I would have received one of those mowers as a REWARD. I never did, but I didn't lose my need for this type of mower. When I saw this mower on desertcart at the $999 price point, I knew it was worth a look-see, given desertcart's very reliable customer satisfaction return policy. So, I put my Navimow through the paces as soon as it arrived to make sure I used my 30 day return window fully. I LOVE IT AND AM COMPLETELY SATISFIED WITH IT. I grant you that other competitor models might work as well and be 'worth' it to the user. UPDATE: June 24, 2024 - For some reason the issue of how often to cut/trim my 3" high lawn came to mind. I used the help feature on the App on my smart phone to "talk" with the help center. (FYI, they only deal in metric units, so be prepared to give the size of your lawn and the height of your grass in metric units) I was quite disappointed with the response I received. The "chat" person said I could only cut my lawn to 6 cm high. But the dial on my i105N clearly shows adjustments from 2" to 3.6". I gave my grass height to 7.62 cm which is 3". I was told that my Navimow could only cut to 6 cm. WHAT!!!! BTW the manual also states that the cutting height in the United States and Canada is 2" to 3.6" or 50 to 90 mm. I did find a posting on Reddit that the recommended weekly mowing time for a lawn be limited to 40 hours. I could not find that information in the manual however. That is why I contacted chat support, unfortunately with no clarification on my question.

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.

### ⭐⭐⭐⭐⭐ Time mapping lawn pays off BIG TIME
*by D***E on June 20, 2024*

I received my Navimow i105N on May 8, 2024. I have now used it continuously since then up until today, June 20, 2024. I estimate this has saved me at least 7 walk-behind mowings with my Ryobi self-propelled mower, which BTW I have loved. I am going to use the descriptor word "mow" through-out my review but you would better understand the work of the Navimow as a trimmer rather than a mower. Once you have your lawn mowed to the height you desire, you can easily dial in the height you want your Navimow to keep your lawn trimmed to. It can be adjusted in increments of .04", from 1.6" to 3.6", which suits me fine. BTW I use my Navimow everyday except on rain days. In this regard my lawn looks freshly mowed every day! I allow it to mow from noon to 7:15 PM, which I have observed is more than enough time to do my entire lawn and also avoid the morning dew and the 20 minute watering I do on my lawn every other day which ends by 7:20 AM on those watering days. I am a 78 year old male living at 40 degrees latitude, which has very hot July and August temperatures, and even now in June. I just don't want to find a cool time of the day to mow, which I typically can't find, to keep the lawn nicely mowed. So, my motivation to use an autonomous mower, whatever the brand, was to stay out of the sun and the heat. So far, I have been able to do that. And, I didn't want one that required putting a wire around my yard. I read some of the 1 & 2 star reviews and could understand the points being made, but in my experience all of their frustrations are resolvable by just taking the time to set up the map for your yard properly. For example, when you come to a curb or a separation of the lawn to a hard service, such as my concrete patio, you should put the "edging" setting to "ride-on." This allows the Navimow to crest the separation, i.e. curb, and continue moving over that portion of the lawn, giving a better trim to that boundary separation. (May I humbly suggest that you watch the videos showing you how to set up a map. Most of those videos are available on YouTube, so you don't have to purchase this first to get access to those instrucions.) Also, the instruction forewarn that you will still need to trim and edge the boundary of your lawn. I use a worx 20v edger/mower to do a fine tuning of the grass height at the perimeter edges of my lawn. So once or twice a week depending on how fast my grass is growing I do a quick trim (approximately 20 minutes around the boundary perimeter of my lawn. I must admit I didn't know that the Navimow is hard programmed not to allow a mapping of more than 500m. My lawn map is 3773ft squared as per the Navimow mapping feature, which appears to fall within the programmed limits for my Navimow. With the battery in my Navimow, it will mow for about 90-95 minutes or until the charge on the battery falls below 15%, then return to the charging station for about 65-70 minutes to get up to 95% of a charge. (BTW it's return to the charging is a sight to behold. I almost feel like there is a "little man" inside the mower guiding it to slide right into the charging port on the charger. I was very impressed with how well it finds the charging station no matter where it is on my lawn when it needs to be recharged.) For the area of my mapped lawn, it takes 2 1/2 cycles to completely mow my lawn. (Also, you have to watch the map on your smart phone as it shows you what it has mowed to really be impressed with how well it keeps track of where it is doing its thing on your lawn.) Forgive me for pasting in this portion of the manufacturer's write-up on the accuracy of the Navimow's use of GPS to know it's position on your lawn, but I attest that it is a statement I could stand by: "RTK+Vision, Fit into Every Garden: Lawn covered by trees? Narrow corridor? However complicated your garden layout is, enhanced EFLS 2.0 got you covered. Customized RTK technology with Vision enhancement provides stable centimetre-level positioning to handle an incredibly diverse range of lawn layouts. Even when it’s under the trees or in a narrow corridor, Navimow still works perfectly with accurate navigation." Now, the lack of a Navimow Access module which allows for theft protection is clearly stated as not included with this model. I believe it is included with the next higher model. If my understanding of the Navimow Access' functionality is correct, it will allow an even more accurate and stable mapping using a cellular signal network, with the first year free of cellular fees but not necessarily after that first year of use. While I have two very tall trees around my yard, the GNSS antenna has successfully found the GPS satellite signals and kept my Navimow within the mapped boundaries. Regarding the Navimow getting stuck, of all the negative comments this is the one I find is completely the opposite of my experience. I have been impressed watching the Navimow get out of a rut in my yard or climbing from a hard surface up and onto the 3" height of my lawn. At first, I got impatient and either picked up the Navimow or gave it a shove from behind to move it along. That is the wrong thing to do IMHO. Give it time. I have had neighbors watch my Navimow work itself out of a stuck position and found it very impressive that whoever wrote the program, first, gave it the mechanical sense to know it was stuck, and, second, programmed in several back and forth and sideways maneuvers to unstick it. It really has to find a "hole" to become totally stuck. That is where good mapping and setting off-limit islands makes a big difference in having a frustration free "mowing." One further suggestion on helping your Navimow from becoming stuck is by setting the mowing direction options for your Mapped Zones for your lawn. I find the diagonal directions don't work well for me. I like the orthogonal directions, such as straight back and forth, or 90 degrees to that direction. One further aside, I had backed the Heisenberg all-in-one robot mower on Kickstarter. As a backer if the development and manufacturing campaign for that mower had been successful, I would have received one of those mowers as a REWARD. I never did, but I didn't lose my need for this type of mower. When I saw this mower on Amazon at the $999 price point, I knew it was worth a look-see, given Amazon's very reliable customer satisfaction return policy. So, I put my Navimow through the paces as soon as it arrived to make sure I used my 30 day return window fully. I LOVE IT AND AM COMPLETELY SATISFIED WITH IT. I grant you that other competitor models might work as well and be 'worth' it to the user. UPDATE: June 24, 2024 - For some reason the issue of how often to cut/trim my 3" high lawn came to mind. I used the help feature on the App on my smart phone to "talk" with the help center. (FYI, they only deal in metric units, so be prepared to give the size of your lawn and the height of your grass in metric units) I was quite disappointed with the response I received. The "chat" person said I could only cut my lawn to 6 cm high. But the dial on my i105N clearly shows adjustments from 2" to 3.6". I gave my grass height to 7.62 cm which is 3". I was told that my Navimow could only cut to 6 cm. WHAT!!!! BTW the manual also states that the cutting height in the United States and Canada is 2" to 3.6" or 50 to 90 mm. I did find a posting on Reddit that the recommended weekly mowing time for a lawn be limited to 40 hours. I could not find that information in the manual however. That is why I contacted chat support, unfortunately with no clarification on my question.

### ⭐⭐⭐⭐ Works well with caveats; see update about tendency to get stuck and potential fix!
*by S***Y on June 22, 2024*

Update: 08/21/24- I came up with a simple fix for the mower's tendency to dig its nose in and get stuck in shallow divots. I tried buying the new, heavy wheels, and they helped some, but I was still having issues. The fix I'm showing in the pictures is an option that gives the front of the mower a bit more ground clearance and appears to have solved the issue for me. It is completely reversible, and does not harm the mower. The one potential risk is in providing more ground clearance at the front, it is now possible the mower could ride up over a foot, or pet laying in the grass, so perform with caution. 1. You will need a 3mm Allen wrench 2. Pop the gray plastic cover off the top of the mower. It's held in with tabs and should snap on and off without issue. 3. There are four black screws around the front edge of the mower, they hold the front "bumper" on. Unscrew those four screws and the whole bumper simply lifts off (screw the screws back into the holes so they don't get lost). 4. Snap the gray plastic cover back on the mower and put it to work. I'm willing to bet that just providing that little extra ground clearance will solve most folks' issues and there won't be a need to spend a hundred bucks on the "heavy" wheels. A little history: this is my second robot mower. I previously owned a Worx Landroid that required burying a boundary wire. That machine worked like an old Roomba and just bounced around the yard, the hope being it would eventually cut everything. It worked ok, but had problems that only grew as it aged so that it was mostly useless by the end of its third season (got constantly "lost" and after returning it to Worx and being told it was fine, and receiving a new base station to no avail, I finally gave up on it). It's with that in mind that I was closely watching Segway's entry into the modern bot-mower segment. Their first edition cut the grass far too short for southern lawns, but this Navimow offers an almost 4" cut height which should allow the lawn to survive the hottest part of the summer. Setup is far and away simpler than the old boundary wire mowers. My only complaint was having to restart the map a couple times because I got into a divot that the mower couldn't back itself out of (and this leads in to my single biggest complaint about the mower in general... more on that shortly). Once setup was complete, it was time to mow. Mowing is a snap. You can either start it manually or set a schedule and let it do its thing. I have the 1/8 acre model mowing the backyard only, and it recorded 404 sq meters of yard. This translates to 1/10th of an acre, so well within the capabilities of the mower. With that in mind, I was a bit surprised that it takes 9+ hours to mow the back yard. This includes three trips back to the charging station (it appears to mow for about 2.5 hours before needing a charge). It does mow in fairly straight lines and interestingly, it mixes it up each time. One day it will mow in lines parallel to the dock, another day it will mow perpendicular to the dock, then at a diagonal one way followed by diagonal the other way. I currently have it set to mow four days a week, as it has an easier time if it hasn't fallen behind. And now the complaint. Your yard needs to be almost putting green smooth. ANY divot, depression or hump can lead to the mower getting stuck. Fortunately, it's pretty determined and it will work to get itself out of a spot, but eventually it will give up and ask for help (and I'm convinced a not insignificant amount of time and juice is spent on this). This issue would be helped greatly if the front wheels were further forward at the corners, and/or the lower lip at the front end was a little higher. Instead, the wheels are tucked back just a little bit behind the nose which means it will hit nose first and dig in just enough to lift the drive wheels up and not be able to back off. My yard is virtually level, with only the shallowest depression here or there, yet it's been stuck multiple times - and if the grass is damp it loses traction even easier. Final verdict: I'm mostly satisfied so far. It still beats mowing the backyard myself, and it will pay for itself in one long mowing season compared to paying someone else. I hope it lasts longer than the old Landroid, and I do wonder if it will receive updates to make it smarter. It'd be nice if, after the last month of mowing it would learn/remember tricky areas and just how much time it actually takes so it could work smarter - but that might be asking too much.
