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

3.5 stars on the robot. 5 stars on customer service, so an averaged rating of 4 stars. 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. If the vision fence is not off, the mower will spend 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, doggie “landmines,” 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.) I decided to break my lawn into two zones so I could re-mow the zone that has the most thick grass and needs extra attention. During peak grass growing season, you will likely need to mow at least daily. Set up was pretty easy with the app and mow progress can be monitored on your phone which is nice. I found that the mower was losing wi-fi signal at the edges of my yard. So, 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. 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 pointless waste of time and money, IMHO.
