Interesting cost analysis there. Let's look at middle range model (and assume that someone who wants to pay someone to mow the grass isn't going to be happy with the cheapest robotic mower (since no one is, those things are rubbish) and say $3000. The OP says cutting takes an hour. Grass needs cutting every week in the summer, and lets say every 3rd week in the winter, so you're looking on average every second year. If you assume that it costs $20 to pay someone to mow something for an hour you can pay someone for 6 full years before you've paid off a robot mower.
How long does the mower last?
I actually have owned two robotic mowers, one from Kress' RTKn line and the newest equivalent from Segway. Decided the tech had matured enough to give it a shot, since they're now satellite guided and actually plan routes rather than using a wire and bouncing around like an old Roomba. I've got about 3/4 of an acre of actual lawn to mow, relatively easy but in a climate where grass grows something like 8 months out of the year. In peak growing season it's really 2 mows a week minimum unless you've planted very specific types of grass that don't naturally grow well in this climate and require a ton of irrigation.
I'll say confidently that these mowers are no longer gimmicks. Honestly I'd be surprised if just mowing a yard is much of a job in another decade.
The Kress as a machine was pretty good, but their gimmick is the owner can't program them themselves and needs a dealer... and the dealers just didn't want to support after a sale. But the new Segway Navimow is impressively good, and fully programmable. Cost $2200 for a model that can mow an acre. Extremely good mapping, easy setup, good interface. Uses multiple cameras for not just collision detection but also to physically reference objects around it and use them to correct for potential drift. Fast enough that it can mow the entire lawn in a long day (about 18 hours, counting charge time).
So in my case, if you figure an annual average mowing of 50 times a year (about 1.5 mows a week during the 8 month growing season), the mower actually pays itself back pretty fast. I was getting quotes around $100 for a service to come in, per mow. If you already owned and maintained the equipment maybe you could get a local kid to do it for half that or less, but certainly no adult making a living would do it... and even at $30 a mow for a high school student the payback is easily less than two years, realistically one full growing season you're about there. Even if other folks are in a northern climate with much slower growing grass you're talking only a few years to pay back.
The main hangup has been that the technology kind of sucked before now. That's pretty much resolved. The only real barriers to adoption now are sunk costs in traditional equipment, unfamiliarity, and difficult yard issues (mainly dense tree cover messing with satellite signals). It's not perfect, but I think we're at the point of "good enough" for widespread adoption.
