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

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.

The next biggest thing I need to know is how long this will last? Set up was easy. Don’t depend on the Owners Manual, it’s worthless. The app guides you through it all nicely. Definitely have to decide you want this in everybody’s way in exchange for not mowing your lawn anymore. It was a big no for one client and for another I was able to put it under her deck enough so the kids could kick soccer balls and not run into anymore. I’m replacing my Husqvarna with this model next Spring. In five years, I have no idea how long it takes to mow 2,500 sq.ft. of lawn with the Husky. In the first hour of using the Navimow I know it takes 1hour 8 minutes and uses 35% of its battery to mow 1,200 sq ft. No more wire to have to fix when critters or people cut it. Love how simple the app is to operate the machine. Have been using it two months and there have been zero issues. I have already winterized it and put it away for the Winter in WA. Cannot wait to set it up again in the Spring. Half hour tops to get up and running again. In the photos I show the positions I tried to set it up. Photo 2 did not get reception and did not move out of the CS. Photo 1 is where it works. Straight back and partly on the concrete is where it can go next Spring. I checked for connection before storing it and found excellent readings on a cloudy day for both satellite and mower in that position under the deck. Yes you can put it at least partially under a deck. The antenna needed to be fixed atop an existing 4x4 post supporting the deck surround. That was what gave us all the connection we needed. The rain sensitivity function works great. Moving the station a few feet is not an issue. The mower and app tell you it’s been moved, you hit a few taps on the screen and it adjusts. Could not have been easier and I worried about it unnecessarily. So long as it gives me three years hassel free mowing, it's worth it.

The robot is definitely an advancement and a good value for money for those that need to mow small areas. However, for my purpose of mowing a front yard, it bothers me that it can’t mow even 1/20th of an acre on a single charge. That’s definitely far from approximation of “up to 1/8th of an acre”. Because my charging station is behind the gate, the inability to mow my front yard on a single charge is really bothersome to me. Another drawback is it cannot cut to edge like Landroid. Finally, it has very awkward turnaround maneuver due to its shape and wheel position which leaves half of the boundary edges significantly untrimmed. Most other reviews will cover the benefits. The gps and lack of wire for $1000 at the time of writing is definitely great. I just wish that manufacturer would not create false advertising in terms of coverage, and then charge additional $300 for bigger battery. This feels almost like Apple trying to charge $200 for extra 64gb of iPhone memory while the base version can’t even perform because iOS sucks up half of the storage. It’s quite maddening when manufacturers choose shady marketing strategies. It’s not like Navimow didn’t know true capacity of their batteries. Update 6/7/2024 The mower is still not ready for a mass roll out like they did. App is underdeveloped, customer service only via chat and it truly sucks, maneuvers are not yet properly developed, scheduling doesn’t work as it should. Since I went all the way, I will be the guinea pig. Any buyers purchasing shortly after this review will probably be too. As long as you don’t care about that and just want “affordable” no wire robomower, you should buy at your own risk [of frustration]. Otherwise I would recommend waiting out this season. Update 6/12/2024 The software gaps are super annoying. Removing one more star. If mower gets stuck, it doesn’t shut down like Landroid. battery dies instead, and after you carry back to charge, it decides to resume whenever it wants. There is no way to cancel mowing cycle following an interruption or low battery return to base. Finally, Segway imposing EU rules in the US. It would still be fine if it were as easy as Landroid to reset “mower lifted” error but the button combo in the error message doesn’t work so you will find struggling over and over with that. Update 8/6/2024 I’m adding 1 star back for the firmware improvement. Now the app allows to select zones for on-demand mowing, a very welcome improvement. Most importantly, now the actual firmware corrected turning maneuver for the curbside edge mowing therefore the mower no longer falls off the edge. One thing still remains missing is being able to cancel the on-demand mowing session while the mower is charging. Since I have to open the gate each time it mows my front yard, it goes back to charge, and resumes automatically, then gets stuck behind the open gate. For those wanting to do manual mowing, and not wanting the mower to be free-spirited on resuming the job without your approval, I figured out a workaround: set night mowing schedule, and disable mowing at night option. It’s gonna complain in the app, but will stay like a good doggy in its base. They also resolved the EU legislation restrictions for resettting a stuck mower in the US market. I’m also adding one extra star for customer service. Although my communications were over chat and email, the customer service is excellent and they will go out of the way to make you happy. For a Chinese based company, I was quite impressed. Certainly their colleagues at Segway mobility branch could learn something from their Navimow peers! Update 5/29/2025 I would be very inclined to knock off a star but I won’t. If you have to ever service mainboard or electronics under the warranty, they will wipe out your entire map and you will have to recreate it from scratch. It might take 2-3 hours to map a property with all the details so this is incredibly frustrating. And to this date developers haven’t created a way to back up the maps.

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.

I bought the Segway Navimow i105N Robot Lawn Mower because the idea of a perimeter wire-free robotic mower sounded perfect for my 1/8-acre yard. It has an incredible concept, and when the hardware aligns, it seems like a glimpse into the future of lawn maintenance. Unfortunately, the execution is mired in a highly frustrating user experience, and I ended up returning mine. The Positives • The Wire-Free Concept: Eliminating the need to bury hundreds of feet of boundary wire is a massive selling point. When the mower has a clear view of the sky, the RTK satellite navigation coupled with the front VisionFence camera handles obstacle avoidance beautifully. • Build and Operation: The actual mower is quiet (around 58dB) and feels quite solid and weather-resistant. Where it Fails Miserably • Incredibly Picky and Difficult Setup: Getting this mower configured is a massive chore. The RTK positioning system requires an absolute line of sight to the satellites to map out your yard. If you have any moderate tree canopy, overhangs, or if your yard is close to a two-story house, the signal drops constantly. Driving the mower via the app joystick to map the boundaries is meticulous work, and if the signal flickers or the mower gets confused by shade, you have to restart the area mapping process all over again. • Zero Customer Support: When I hit an absolute roadblock with a firmware loop during initialization, I tried reaching out to Segway customer support. Getting a response from a real human is incredibly difficult. It feels like you are shouting into a void of automated troubleshooting bots and Zendesk tickets without any real, urgent technical support for a machine that costs several hundred dollars. • Glitchy App Connectivity: The integration between the Bluetooth pairing phase and moving to a 2.4 GHz Wi-Fi network dropped repeatedly during my initial configuration. For an "autonomous" machine, it required an exhaustive amount of manual babysitting. Final Verdict If you have a perfectly flat, wide-open lawn with zero trees and absolute unobstructed views of the open sky, the Navimow i105N might work well for you. However, due to the painfully difficult mapping setup, signal sensitivities, and abysmal customer support, the frustration quickly outweighed the benefits. I ultimately gave up and returned the unit. It is a below average 1-star piece of tech that is just not ready for mainstream, plug-and-play consumers yet.

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.

Update Nov, 2025: Had to reduce this to three stars. Over time it has become obvious how badly this mower does navigating around objects. In wide, open yards it does a pretty good job. But trampoline legs? Swingsets? Forget it. It doesn’t get close to the edges either. It keeps leaving 1-3 feet wide gaps along the fence or around certain objects. It’s like it’s *too* careful and gives everything a ridiculously wide berth. I’m fairly disappointed at this point and not happy with the purchase any more. It needs to have much better navigation features, like perhaps bumpers or more cameras and sensors so that it can more accurately avoid objects without going 1-3 feet away from them and leaving huge patches of uncut grass. Original review: I’ll start off by saying I was hesitant to purchase this. I read a lot of reviews and wasn’t sure this was the mower for me, but I knew I couldn’t deal with another boundary wire situation. Prior to this I had a Worx Landroid for 3 years and it was such a hassle with how much it got stuck and the amount of times it would dig up its own boundary wire and cut it. I decided to give this mower a shot with the reassurance that I had 30 days to return it if I didn’t like it. When I first opened the box, I was overwhelmed with all the wires and pieces it came with. But really, once I figured out what was what, set up was incredibly easy and fast. The only “difficult” part of it was cable management to ensure no wires were down on the ground where the mower will be cutting. I easily found a spot in my yard where there was good GPS signal (side note: the antenna AND the base both have to have good signal, so you can’t have the base go against your house if there’s any overhang from the roof like mine). The robot can actually help you figure out where the best place is by driving around your garden perimeter and showing you on the app a little map with all the good signal points. I got mine set up along my fence line, plugged in the power cord, the antenna, and did the cable management and bam. We were ready to map. You can either have the robot map by itself following your perimeter, or you can drive it around RC car style with the app and map it yourself. Once that was done I had it start mowing immediately and I’m very impressed with how well it did. My yard was slightly overgrown and it got it all down nicely. It can do my entire yard in one charge no problem, too. It took probably two hours or so, so it’s not crazy fast but it’s definitely faster than my old Landroid that just bounced around randomly and left patches everywhere. It did a really good job, and as you can see from the pics it left nice straight lines which I love. So, I think for the price this is a really good value for a non-wire mower, especially if it’s your first one like me!

This lawn mower robot is a game changer - it an incredible application of the latest tech and engineering to make a chore an afterthought. Is it perfect? No, not at all. Is a giant leap forward? Absolutely. The confluence of GPS, Wifi, Bluetooth, and camera-based AI makes this robot completely different and supremely effective. Using your phone and the robot, you map out the areas of lawn on your property. The robot orients itself with GPS and doesn't miss. IT cuts grass very efficiently, and makes hardly any noise at all. You can run this in the middle of the night and no one would know! The app keeps track of where it is, and you can monitor its progress easily and intuitively. It varies its pattern on every use, and it hits the stragglers it missed on its previous mission. Set up is a less intuitive than it should be, but after some trial and error, you can figure it out easily. I mapped out two areas of lawn that are separated by our house, and it seems to work well. You will have to create "channels" between the areas of lawn that the robot follows. You will have to manually open gates of course, but it makes it from the back to the front reliably. The app reports progress clearly so you are always aware where the mower relative to the complete task. Some things that I hope will improve with OTA updates: You have set up all of your lawn zones as a single task and you cannot do the back and front independently. I have it set up to do my back first and then the front. When it is done with the front, the mower has to enter my back lawn and then make it back to the charger. My charger is set up between the lawns so it would be more efficient for the robot to go directly to the charger without going to the back lawn first. I mistakenly selected the option to map the shortest path to the charger, which made the mower try to go through a brick wall. The camera detected the wall, but then the mower got confused and just couldn't find its way to the charger - it was relatively amusing to see it try, but it was obvious that it wasn't going to succeed. It was not intuitive how to change the channel - I finally discovered that the mower needs to be in the boundary of one of the lawn zones to allow a channel to be selected for a redo. Once I figured this out, it was relatively easy to set up a channel that allows the mower to automatically navigate to the charger. I also found it is better to turn off the camera when navigating a long channel, e.g. the channel from the back lawn to the front lawn. If the camera is on and there is something close to the path (a stray branch from a plant, a planter, etc.), the robot things it needs to assess if it can get around it and then it can do some relatively creative rerouting, sometimes unsuccessfully. Turning off the camera results in it confidently navigating the path to the next zone. If you have to stop and lift the mower due to an obstruction, the app instructs you to press OK and the home button to restart the mower. That doesn't seem to work. It does clear if you put the mower within the boundary of a zone, but the conflicting directions make things somewhat unclear. Overall, I am very comfortable with the machine. For the most part, it does what it says it will do, and is very reliable. I expect it to continue to get better with additional firmware updates, and the positives far outweigh the niggling negatives that I have observed so far. Highly recommended
