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

The media could not be loaded. I've had this mower about a month, and in that time I've become more and more impressed by its performance. It does everything it promises! Let me tell you about it.The Navimow app allows me to map multiple regions of my yard that add up to a maximum of 1/4 acre. My property's mowable area is about 2/3 of that, so I haven't pushed that limit. It took me a few tries to get good at mapping - which can be a little frustrating, because I wanted it to be one-and-done. But once I understood how the mower uses the map, I would occasionally delete and remap a part of my yard, or adjust the map to tweak whatever it was I wanted to change. Here are things I tweaked to get better results:-Whether the border was a "don't cross the border" edge (the default edge type, shows up on the map as a solid line), or a "crossing the boundary is OK" edge (you have to toggle to this if you want it) - shows up on the map as a dotted line. You can switch between these two as often as you like as you create or adjust every region/map you want to mow! So there are places where I have a solid border so that mower doesn't overshoot it and get its hind wheels caught on a concrete rainspout trough or a particularly problematic exposed tree root, but a dotted border where the lawn meets the driveway or the sidewalk, so the mower can overshoot and make sure to capture all the edges.-Which directions the mower will use for its rows! I've got one region of my lawn where there are grooves in the ground where I think tree roots used to be, but rotted. the wheels of the Navimow will get stuck in the ruts and the 'nose' will run aground, and it can't free itself, when the mower is going in the same direction as the grooves. But when the mower is going at any other angle, it crosses the ruts with ease! So I edited that region of the map and told the mower to never use that particular orientation for aligning its rows, and now I haven't had to rescue the mower from getting stuck in one of those for weeks. I used the same trick to keep the mower from popping its rear wheels over the edge of the curb where it was getting stuck. Now it gets stuck there a lot less!When I bought the Navimow I knew I'd be asking a lot of it. The two challenges that I knew I'd be risking overwhelming it with are with steeper slopes, and with tree cover interfering with the GPS signal. I feel I have pushed each of these to the absolute limit, but it has worked out just fine. The steeper slopes situation, I simply avoided the reliably-too-steep regions when drawing my map, aware that I'd have to occasionally mow/whack those areas myself. but we're talking 5 minutes of effort every few weeks, and that's well worth it to me. As for the tree cover situation battling with the GPS signal, I was worried this was going to be a deal-breaker for me. I have tree cover over probably 95% of my property. I figured it there was going to be a problem, this would be it. Well I was able to plant the GPS receiver on the included pole at one corner of my garage where it happens to have a decent view of a small cone of the sky, and - amazingly - that's enough for it to navigate my entire lawn! I did have plans to mount the antenna to the ridge of my roof, where it would have a lot more sky visible (it would be able to see from straight-up to about 45-degrees in all directions) - but that hasn't proven to be necessary yet. I do not have great signal at all times in the current setup and there ARE times that the mower refuses to do certain things until the signal is better. That can be a little frustrating, but I understand that if I want to fix this problem it means getting up on my roof. So far I've decided patience is the more attractive option. Things it occasionally refuses to do until it has better GPS signal include: Adjusting the map, Relocating the power station on the map, and manually initiating mowing!Since I only have great GPS signal some of the time, I've set up a mowing schedule so that it can attack my front yard one day, my back yard the next day. Then I take a day or two off, then repeat the cycle - this way it mows my entire yard twice a week. This keeps things looking tidy, leaves enough clover for the local bunny rabbits to nibble on, and makes me feel like I'm getting my money's worth by having a lawn that looks constantly tended-to without me having to do much of anything at all.When adjusting my map regions I discovered that if one region overlaps another region, the mower software will try to join them into a single region. That was frustrating a couple times and I had to exit out and try again. NOTE: IF YOU EXIT OUT WITHOUT SAVING, EVEN IF IT HAS TOLD YOU YOU CAN NOT UNDO YOUR CHANGES, YOU CAN USUALLY RETURN TO THE WAY IT WAS BEFORE YOU STARTED! Make sure you save the map every time you successfully do something you're happy with. It would suck to have a later mistake force you to wipe out work you wanted to keep. So when I broke my back yard up into two halves, I made sure that the border type was the dotted-line "You can cross this border / overshoot" type of edge on both regions, and I made the edges as close to each other as I was able to without them touching... and voila! After it has mowed both halves of the back yard, you can't see that there is a dividing line anywhere in it.Another note about adjusting the map: you can add or subtract territory to/from an existing region of the map. The software makes the best guess as to the final shape of the map, given how it started out and what new border you drew... and it offers you two options to pick between. It calls them "A" and "B", and shows you in blue on the map what the final territory will look like depending on which one you pick. You can look at both of them before you say "Yes", and if neither suits you, you can exit out (look for the "X" in the upper left corner) and try again. When you're adding or subtracting area, you once again get the option of which kind of border, solid or dotted, you're picking. This has been fantastic for me as I saw how the mower did with my original borders, and I decided to change the boundary lines for better results.There are "DO NOT ENTER" zones you can draw around things like flower beds. In some of the tutorial materials they also show you drawing such a boundary around, say, a tree. From my experience - and this is just in my own yard, and I do not have mulch beds around my trees - don't bother. Just let the mower's obstacle identification take note of the obstruction and avoid it. I have had great results with this! The mower has occasionally gotten stuck on an exposed tree root while exploring the area around the tree, but I have watched it learn where the most problematic roots are and learn to avoid them. How? I'm not sure. I guess it remembers where it's gotten stuck in the past and just tries not to roll over that spot, in that direction. I've definitely seen the mower approach a root it's gotten hung up on in the past and approach it from a direction that it has figured out doesn't present a problem. It's pretty impressive!When setting the mower free in my yard for the first time (once I had drawn the geofencing maps), I had the urge to rescue it when it got caught on something. But I was able to hold back and give it the chance to use its programming to work its own way out of the situation. Occasionally it would alert me that it was stuck, but the majority of the time it would eventually figure out how to free itself. As time has gone on it's gotten better at freeing itself. I'm considering giving it spiked wheels to help with traction, but I don't know for sure whether I'm going to do that.When the mower does get stuck and needs to be rescued, you can tell it to resume either with the app or by pushing the RED --> OK --> MOW buttons on the unit itself (or RED --> OK --> HOME if you want to send it home). The instructions on the app tell you to hit the STOP button (that's the RED button) and then the "OK + MOW" or the "OK + HOME" buttons, which (to me) sounds like I'm supposed to push them at the same time. Nope, gotta do it in sequence, pretty quickly - like you're counting "1, 2, 3". Sometimes I forget which order and instead I'll hit RED --> MOW --> OK. One or the other works. There have been times that I've needed to pick it up and plop it down on the charging pad because it was too tired to get there on its own, but usually if it has battery left it'll do it on its own just fine.The photos show my mower in action. One's indicative of the amount of tree cover I have in pretty much all directions all over my property. As the mower sits on its charging pad throughout the day and also as it's mowing my lawn I'll watch the light on the mower vary between "Meh" and "Good" signal. When there's a scheduled mowing time, it'll start at that time. But if I tell it "Go mow region 3" and the signal is "Meh", it's not going to start until the signal improves. So be aware of that. It's got opinions. There are, however, reasons for those opinions. The video shows the mower attacking my front yard for the first time. You'll see that, in the process of avoiding trees, it misses areas of the yard. Later in the mow it did go back and get those areas before it finished - you can even look on the map on the mowing app and see, with surprising precision, where it has and hasn't mowed. I have noticed that it doesn't always get 100% of the region every time it mows. But because it's mowing a few times a week, I've also noticed that I don't notice it missed anything, and the next time it mows it usually catches it.If anything interesting changes I'll update my review, but all in all I have to say that I am absolutely thrilled that the mower is doing such a fine job. Summer where I live is horribly hot and humid, so not having to worry about this task is a great thing - and the mower cost less than paying a professional service or a neighborhood kid to mow for a year (kids are charging a lot now!), so it's also a financially good investment. Also a big conversation starter - a lot of folks want to stop and chat with me about it when they see me out front. I'm always happy to gush about it to them.NOTE: If you want worthwhile anti-theft, you have to buy the 4G module separately and install it, or at least get an AirTag type thingy and stick it somewhere so you can go find your mower if it's taken. But the mower is useless without its charging base and GPS maps, so if someone steals it it's no good to them.Happy not-mowing!UPDATE:::They made it even better.There are some steeper parts of my yard I simply excluded from the mowing maps and had to tend to myself in some other way - even though I knew that if the mower approached them from the right direction it would be able to do a fine job without getting mired. But while I can give it certain orientations to skip when mowing its rows, there's no way to get clever/detailed and tell it to always use this shallow path to go up to the top of this steep part but then mow the steep area only downhill, then loop around up the shallow path... If I was manually steering the mower, I was teaching it new boundaries, but to get it to *mow* them I had to tell it to go mow, and then it would do so using its own internal smarts.Well now I can manually drive the mower around while mowing! I can turn the cutting blade on and steer the mower around. It might look a little silly standing there in my yard holding my phone up to drive the mower, but I'm much happier doing this than having to get out my old push mower, or a weed wacker, or any of the other ways of cutting lawn that's too long.This is the #1 upgrade/capability I'd been wanting since I got to know my mower and its limitations, and now it's here!Ok. That's all. Just had to make sure you knew that this is now an available capability. It's fantastic!

4 stars on the robot. 5 stars on customer service. I just finished my first mow with the i110N. My initial reaction was "Hey, I could get used to this!" Then I saw how the mower handled the rest of my lawn. I have an imperfect lawn that is a bit uneven, with several flat bare patches, and different kinds of grass. It's not a perfect, fantasy lawn as shown in the robot mower videos that would allow a robot mower to function at its best. This mower's optical system sees bare patches as obstacles and mows around them, even if there are a few bits of grass growing there. The same problem occurs where there are flat patchy spots where there is moss on dirt, but not much grass. Turning off the vision fence feature helped to reduce the problem, but the mower still spends a lot of time being confused and getting stuck in the middle of perfectly flat areas, that it literally can't see its way out of. This mower does a poor job of cutting the thicker tufts of grass. I will have to manually cut those with a string trimmer. It does great cutting thin bladed grasses and grasses that naturally grow more outward than upward. With each pass across the lawn, the mower leaves a bit of uncut grass on the edges of the strip. On followup mows, the mowing pattern is changed and most previously uncut bits are taken care of. I get the best cut when I mow then immediately re-mow an area - especially with thick grass areas (thick - not tall, grass.) The mower handles hills fairly well, coming at them from different angles to make sure that the whole thing is mowed. Note that if the blades are too low or the hill too steep, the mower will have problems mowing the hill. If parts of the lawn are missed, the mower will remember and go back over those areas to make sure they are mowed unless they are completely bare, in which case the mower sees those areas as obstacles. On the higher blade setting small sticks and small rocks are not an issue. Pine cones and small pine/tree branches need to be removed before mowing. This thing is S--L--O--W. It takes almost an entire day (1 1/2 - 2 full charges) to mow 400 square meters (478 square yards or about 1/10th acre.) So, I decided to break my lawn into two zones so I could mow one zone at a time. During peak grass growing season, you will likely need to mow at least every other day. Set up was pretty easy with the app and mow progress can be monitored on your phone which is nice. Since my mower was losing wi-fi signal at the edges of my yard, I bought the 4g module and that solved the problem. Navimow says that the cost for annual 4g service with the optional module is $32.90 after the first year of free access ends. (Price as of 3/10/25) In summary, this is a fairly dumb device, that does an average job. At least I don't have to do as much mowing as I did before, so that's a win. Tip: buy the 6 blade cutter for a better cut. https://www.amazon.com/dp/B0DLKC7KB3?ref=ppx_yo2ov_dt_b_fed_asin_title A far as robots go, this one won't be achieving "overlord" status any time soon. but if you aren't too picky, it will probably be good enough for most average yard needs.Navimow customer service reached out to me as a result of reading my review. At a time when good customer service is very hard to find, the Navimow support folks have been a fabulous shining example of what it means to provide excellent customer service. Their communication has been amazing and I feel like my concerns were heard. They offered ideas and suggestions for how to improve the mowing results, which were mostly helpful. The customer service alone might be enough to justify buying this mower and I upgraded my rating as a result of my customer service experience. Now, if only Navimow could just provide some way to secure the mower over night so that it doesn't rely on a module to send a phone alarm should the mower be stolen at a time when the owner is sleeping, away from their phone, or not in a position to track down and confront a mower thief. There needs to be a way to secure this and other robot mowers BEFORE they get stolen, rather than alerting owners after the fact. The module works great to extend wi-fi access across my yard, but as a theft deterent, it is a waste of time and money, IMHO.
