Segway Navimow i110N Robot Lawn Mower Perimeter Wire Free 1/4 Acre RTK+Vision Robotic Lawnmower, AI-Assisted Mapping, Virtual Boundary, APP Control, 58dB(A) Quiet, Multi-Zone Management

Summary: After a few weeks, while not perfect (still working out a few kinks), I'm giving this 5 stars because it is very impressive and I am very optimistic that it will reach near full independence. For yard situations like mine or simpler, I would definitely recommend it. Value: I have a ~7500sqft (0.17 acre) yard. I paid over $1k for mowing in the last year, and that is definitely on the lower end of what I could have paid. Including accessories I had to procure (mountable antenna, and traction wheels, see below), I'm sure this will pay for itself in 2 years, which is before the 3 year warranty expires. I do need to use a string trimmer on a majority of the edges of my yard and a few islands, but that will only take ~12 minutes every week or two. Installation/setup: It's definitely very picky about where to place the antenna and station, but I found the antenna to be more picky. I strongly recommend the antenna mounting kit, or a DIY solution. The station wasn't happy for me under a small eave so I had to rethink where I wanted it, but it's working well on the south side of my house, touching the wall, with a pretty good view of the south. The app is pretty good and setup is pretty easy. Reliability: My yard is mostly very flat, with a few protruding roots, small slopes/crevices, and storm drains. I had to configure no-go zones for my roots but not a big issue, can trim afterward. My slopes, especially around the storm drains, definitely push the limits of the stock wheels. It mostly can recover smartly and still get the job done, but it slows it down considerable. I 3D printed some better traction wheels (can find models online) and that seems to largely fix the slope issues in my case. You could also buy the $100 traction wheels if you don't have access to a suitable 3D printer. It can get stuck in small crevices/dips in the yard, so you may need to put down a bit (like an inch) of dirt in a few areas to prevent that. I still haven't gotten it to do my entire yard without getting stuck, but I'm getting really close. It got 98% done yesterday and then got stuck on the curb twice, probably because I configured that edge to be a ride-on boundary. I think if I remap that zone to not be ride-on, it should be fine. It did trample over one of my plants slightly outside the boundary once, but it hasn't done that again. There wasn't an obvious transition from yard to bed so it probably thought it was just more yard. It can do my entire yard in one day during daylight, with an hour or two to spare, so a full quarter acre is likely pushing it for a single day unless you enable night mowing. But no reason it can't be done in two days. Performance: The yard looks quite nice when it's done, I like the small light tracks it leaves much more than big riding lawnmower tracks. It occasionally misses small portions of grass, but I have it doing the whole yard twice a week so it shouldn't be very noticeable. This lawnmower allows the grass to be cut much more frequently, which means smaller clippings, which is healthier for the grass and looks better too.

See video: Yes, it really is that quiet. Chickens make louder noises than this thing. Let me start by saying- this machine is not really meant to cut tall grass, but it will do its damnedest lol. When I first bought it, my grass was pretty tall, and it kept getting stuck on the tall grass, but once all the grass was short, I have never had to think about my lawn other than the edges, honestly! It does a really great job maintaining the lawn, and I scheduled it to when I'm usually not home. So some pros: 1) super quiet 2) no pesky perimeter wires ( I had previously bought one that used a perimeter wire and let me tell you the "savings" were NOT worth it. The previous perimeter wire one constantly got stuck on obstacles in the yard, and I could not easily edit the map like I can with this one) 3) very low maintenance 4) your yard will always be the length that you set it to Now, there ARE some cons to be wary of, which is why I give a 4 star rather than a 5 star, though make no mistake- I would recommend this product to most people. 1) It does get stuck pretty easily on loose soil and on random bits of the yard, so you may need to edit the maps a couple of times before you reach a sweet spot 2) the GPS set up is admittedly kind of a pain in the ass. Expect to spend a whole afternoon or two setting up. Now that I've had it for about a year though, I've only needed to edit the map a handful of times after setting it up. Additionally, if it goes behind a wall it begins to lose its navigation accuracy. I think this would be solved with additional navigation posts. 3) It is kind of heavy. I can lift it up, but for people who have issues lifting things from the ground, you may have issues when this gets stuck, which it does from time to time. I have found that I need to bring it to its home base a handful of times a month when it's navigation makes it get stuck. 4) You can't just place it anywhere. The GPS system is really finicky, and if you see a spot where it would be "out of sight", unfortunately that may not be the best spot for its set up. The wires* they give you are very long, so you do have quite a bit of leeway, but unless you get creative you may be left with a kind of "unsightly set up" . For us, we just needed our lawn mowed to satisfy our neighbors and renters, so the unsightly wires are really just an " us " problem when we went outside lol. Other than that, I'm very satisfied with this product. It has saved us from mowing the lawn during the hot summer, and being that the going rate for a decent person to mow the yard is around $20 a mow for a yard my size, this baby has more than made up for its cost, and it never cancels!
