If you've got a small lawn, a robot lawnmower could change your life, and one I think you should get is the Segway Navimow i110n. The idea of dropping $1,000 on a robot lawnmower might seem beyond the pale, but I'm going to make a bold claim: This thing is going to pay for itself, one way or another—especially if you grab one during the current 25% off Prime Day sale.
Why you need a robot lawnmower
If you currently pay a gardener or landscaper something between $40 and $75 a visit, having a robot keep the grass cut can trim those visits way back. Cut even one visit a month out, and you'll have paid for the mower in less than two years. Sure, someone still has to do a little edging and the lawnmower isn't going to trim your bushes, but you won't need to worry about the lawn all spring, summer, and fall. Even better, because the robot can mow as often as you like, your lawn isn't going to look scruffy between visits. It can always appear as if it was just mowed, if you're that kind of lawn freak. If you know someone who is having trouble keeping up with their yard due to age or mobility, this tool can solve that problem, too.
Even if you cut your own lawn (or had children specifically so you'd always have someone else to do your yard work), a robot mower will still save you grief. Even if you don't mind mowing your lawn, having a robot do it frees you up for other gardening tasks you're likely to enjoy more. Your robot lawnmower doesn't need to be hassled to do the job, incurs zero risk while mowing, and doesn't require upkeep the way your standup mower (and child) do. Your robot mower will never ask for a bigger allowance. You can even share a mower with your neighbors, further amortizing the cost.
Speaking of neighbors, they'll deeply appreciate the intense quiet of a robot mower. Sure, electric mowers are quiet, but robot mowers are so silent you often question if they're working.
Why the Segway Navimow i110n is my pick
Here's why I think you should get this mower: It's super quiet, and it requires almost no intervention on your part. Unlike many mowers I tested, the Navimow doesn't need to be assembled—unbox it and it's ready to go. Setup is not only simple, but kind of fun: You walk the mower around your yard, using your phone like a remote control. The robot maps the inside of that area, and is smart enough to avoid obstacles like raised beds.
The Segway improves over time, getting closer and closer to objects in the way, like those garden beds, and in all my testing, it never once left the yard or the zone I set up. Of all the mowers I've tested (around 20 at this point), the Navimow was the one I never had to worry about going rogue—it always mowed and returned promptly to the base station to charge.
This is a big buy, so if you're interested, a 25% discount is worth taking advantage of. And if your lawn is smaller than 1/8 acre, you can grab the i105N instead; it's $300 cheaper and also currently 25% off for Prime Day.
