"Our lawnmower broke -- it's an electric, rechargeable Craftsman mulcher mower, and it seems the battery won't charge any longer. So, now we have to find a new lawnmower. My wife, being an environmentalist, listed her requirements: electric, zero emissions, and mulching. Luckily, she never said she didn't want robot to mow our lawn, so my solution so far is the Toro iMow. Unfortunately, the iMow isn't selling well; They only sold about 500 units last year and Friendly Robotics's US local company declared Chapter 11 bankruptcy earlier this year. They've already dropped the price 50% since it's introduction, so I don't want to pick one of these up and then have Toro discontinue the model. Has anyone had any experience with one of these things? Does it really work? Will my lawn look good afterwards? Will I spend 3 hours watching it to make sure it doesn't run over a neighbor's kid? Does it have little arms that sprout out to run the edger? Should I look for something else, resigned that my dreams of a little robot to mow my lawn are still years away?"
"Apparently, the way it works is you lay out some conductive wire along the perimeter of your lawn, and let the iMow loose. It first mows the perimeter, and then it zig-zags through the inside until it completes your lawn. It looks a little random in action-- kind of like a teenager half-heartedly mowing the lawn after he's been told 5 times to, 'Do it already!'
After a little searching on Google, I learned a little about the mower. Apparently Toro rebrands the Robomower made by Friendly Robotics. There are some mpegs of the mower in action on their site. The movies are pretty funny to watch -- check out the "Handling a Tree". Unfortunately, the robot doesn't seem to be very efficient and there are no good shots of what the lawn looks like afterwards. There should also be a movie showing what the neighbors think when they see this thing in action."

For about $50.00/acre I could dress my little brother up in his R2 costume and send him over with the push mower...
Why not just use one of these instead?

Zero emissions, mulching, no batteries or
electronics to break, and you get exercise
while mowing the lawn!
- No more than 5,000 square feet of lawn.
- Yard is flat, with slopes no greater than 15 degrees.
- Yard is free of excessive obstacles.
I dunno about your yard, but that's not even close to mine. I break all those rules, and I think most of the yards in my neighborhood do, too.www.HearMySoulSpeak.com

The environmental impact of toxic battery manufacturing and disposal is far worse than engine emissions.

I hope you have a wind mill or a solar panel to charge your lawn mower otherwise your not being very environmentally friendly with all the coal that was burning for you.
Unfortunately, the iMow isn't selling well ; They only sold about 500 units last year and Friendly Robotics's US local company declared Chapter 11 bankruptcy earlier this year. They've already dropped the price 50% since it's introduction[...]
Umm... didn't you pretty much answer your own question? They dropped the price in half and still no one's buying it, and they're on the skids to boot.
Seems like the answer is pretty obvious to me...
WWJD? JWRTFM!!!
buy this if you want to be environmentally friendly!!
So, how about you look for a new battery rather than a super robot slave army? I mean, super robot slave armies are nice, but in the end rather hard to find at your local hardware store. Also, let's say you do go for the robotic minion strategy of lawn management. If you're worried about your robotic minion being discontinued, and the price has been dropped 50%, why not just buy two and keep the second as a spare?
And, just for some extra sodium chloride for your wounds, have you considered the environmental consequences of chunking the whole damn mower or the battery (full of heavy metals) compared to the environmental impact of a quality gasoline-driven mower that'll last longer? Or even just nuking your lawn and putting in wild flowers or a rock garden? You'd be amazed how much pollution the average picket-fence-and-one-point-five-kids lawn contributes to your local watershed in the form of storm runoff becuase of all the crap you have to put on it to make it look "nice" ("nice" here evaluating to the traditional standard of perfection and control accepted by society, not natural chaotic beauty). You need to evaluate your real goals; is your priority the environment, a nice lawn, or no time spent on lawn maintenance?

Even better build 2 replacment battery packs and spend the 20 to 30 dollars at HarborFrieght for a solar battery charger.
m block).net
Look online at major electronics sites for NiMH battries. Honestly, If you post the specs for the existing battery pack, there are enough knowledgable people here to tell you excactly how to build a replacment battery pack and an appropriate charger.
Or contact me at pbcoder@(removethespamblock).prodigy(removethespa
and I will help you with finding the right components. You really should be charging this with solar or wind or both else your wasting your environmental concern effort.
Someone on K5 got one of these and reviewed it in their journal.
"My wife, being an environmentalist, listed her requirements: electric, zero emissions..."
His wife, being yet another NIMBY-mentalist, prefers that it be electric, so that the 'zero emissions' instead will be sulfur emissions at the coal fired plant, or long term radioactive waste at a repository, rather than that awful gasoline smell that hurts her nose.
(NIMBY=not in my back yard)
My wife, being an environmentalist, listed her requirements: electric, zero emissions, and mulching.
Just because a {Mower, Car, Bus, anything that moves without Animal power} is electric does not mean it is zero emissions. The power has to come from somewhere. It may not be produced in your back yard, but it is most likely produced in someone's back yard and it does pollute in some fashion. It may not pollute as much, but the only zero emission power plants I know of are hydro and wind.
A note on Hydro: just because it does not pollute does not mean it is environmentally friendly. Just ask any fish if they can get back up stream to spawn.
For example, a team of U.S. and European scientists recently found that mowed grass emits hydrocarbons at a level of 20 to 60 parts per billion--which is comparable to the level released by the gasoline-powered mowers cutting the grass. In an article published this year in Environmental Science & Technology, the team reported: "The results of these experiments suggest that common lawn mowing releases substantial amounts of reactive VOCs and should be considered in urban air-quality control strategies."

Doesn't anyone else think lawns are just a bit silly? What's wrong with forest floor? Plant some nice big shade trees, don't rake the leaves, have a wild flower spot, some herbs and veggies.. whatever, all done, and your only emission is oxygen.
Our relatively new home has made me feel like a grass farmer all summer. What an ass I feel like spending hours upon hours farming the perfect turf.. with NO CROP. We are buying 8 large locally indigenous trees this fall and roto-tilling much of the back yard. The goal is to have an attractive semi-wild looking area that is really a food and flower producing garden, and where it isn't, it'll just be good old forest floor. I will feel a lot better about watering that.
Operator, give me the number for 911!
I suspect that large-scale power generation can produce more power for less pollution, since they don't have the space and dynamic load constraints that cars and household engines have.
As for hydro, I don't really give a damn if a particular fish can spawn. I'm a bad greeny: I care a lot about things that poison me or screw up the ecosystem in ways that endanger my food supply, but not much about anything else.
Batteries are only good for a certain number of charging cycles, and/or other limits based on the various technologies.
Go to a battery place, there are such things now, and bring your old battery in for recycling, and take back a new one.
Far better ecologically than discarding and replacing.
If you use a pushreel lawnmower, they use no gas, oil, or electricity, and dont make any noise. They don't mulch, so your wife will need to make a compost pile, or just leave the clippings where they fall, which is not a problem if you mow often enough. Sometimes primitive technology can solve modern problems.
The Uncoveror: It's the real news.
That's hardly environmentally friendly. And it also doesn't speak well for the technical ability of a slashdotter. The obvious thing to do is not to buy a new lawnmower, but to replace the rechargeable battery.
for maintaining grassy areas. Cows are too big for most people to manage. Sheep aren't good loners, so most small families prefer a goat. You can also get milk from them and make cheese, provided you haven't loaded that lawn up with diazanon like a dope.
My God, it's Full of Source!
OUTSIDE_IP=$(dig +short my.ip @outsideip.net)
I think they were the first ones to make these types of mowers; saw a battery as well as a solar cell model on their page a year or two ago (http://www.husqvarna.com/). I guess many makers of lawnmowers/power tools are on this band wagon or are trying to get on, so surf a few web sites and don't get yer panties all in a knot over one maker that is going down.
As others pointed out, you could also investigate alternative ground cover. I'm unfortunately not into gardening myself, so this is all out of that store of useless info you hear somewhere and only listen to with half an ear, but I once heard of plant species which would do nicely as lawn and which don't grow more than a few millimeters in height, so you don't need mowing at all.
Free, as in your money being freed from the confines of your account.
If your wife is really so much of an environmentalist, she'd be out there every week breaking her back with a nice clean old-fashioned manual rotary mower. It's good exercise too.
Why not rub it in by purchasing a big old 15 HP gas-driven monster. Make sure to get it second-hand, and make sure that it belches plenty of toxins and leaves soot everywhere. Also be sure never to change the spark plug(s) or perform more than the minimum maintenance required to keep it running poorly.
Environmentalist indeed.
One future, two choices. Oppose them or let them destroy us.
I don't know where you can buy one but this looks promising. Solar powered, zero emissions, nearly silent, fully automatic. You just buy it, bury the wire and let it go. No mention of price and how much of a slope it can handle. Max lawn size is 1200 m2. Definitely puts the Toro to shame on the enivornmentally friendly aspect.
They handle slopes. They aren't limited in acreage. They don't need to be recharged. They convert grass to fertilizer. Your kids will love them.
And besides, you'll have a *goat*! There are tons of people in "Do Cyborgs Dream of Electric Sheep" that would kill to be in your shoes!

The first time this manages to mow over someone's foot, the company is going to get sued, pay out the ass and then drop it like a hot potato.
Image recognition is cool, but there are a lot of places to perfect it on other than on self-propelled things with high-speed blades.
I mean, make the same thing but with a broom or vacuum cleaner for indoors or something. Indoors would be flatter, anyway.

My 72yo mother uses a reel mower, and she loves it. It's easy to push, does a great job with the grass, and is quiet. You have to mow a little more often, since it mulches the clippings and doesn't work as well in long grass. Great solution, though.
This isn't as much "normalization" as it is "don't take so many drugs when you're designing tables."
Arguments in the robo-mowers favor were that he has a simple small yard, few obstructions (house, two trees, sometimes car in driveway, never any toys, kids, pets, etc.) His land is fairly private so there was little fear of the mower being robo-napped. The biggest feature was he has little time at home, a passion for gadgets, and grass 'stuff' triggers his allergies.
Those pointed out the mower does a moderately good job. It doesn't hurt anything but it's coverage isn't optimized, once done following the perimeter it pretty much goes on random and trundles around the yard without any apparent strategy. Thus while the drunk walk does eventually cover all of the yard it's also quite inefficient at doing so, may mow the same spot a dozen times while the wedge next to it remains untouched for a long time.
'Course efficiency isn't all that important as long as he's not the one out there doing this all. And as long as it is sunny out the mower just keeps going on its own so he usually simply puts it out on a sunny morning and comes home after work to find the yard clipped & reclipped. Pop the 'bot back in the garage and the lawn is ready for the weekend.
However, he is in a particularly good situation for the mower. The theft concern would be a big one for most folks; the fear of some bored kids coming along and "liberating" the 'bot. There's also the point his yard is absurdly simple with few obstructions, nothing that the 'bot could ever accidentally mow-over. Also his yard is sunny, small, and the grass is never allowed to get tall.
Cost-wise it's pretty much a trade-off. So far the mower is competitive with having a lawn crew come by once a week. On the other hand they'd also edge the walk, fertilize, leaf-blow, etc. Should the mower last another season or two without repairs it'll have justified itself mostly. Should something break, well, it's not like the lawnmower-repair/bait-shop down the street knows how to fix one of these...
My own parents go the lawn-crew route and are quite happy. Dad isn't up to mowing the yard and they do a mostly good job. The lawn always looks great; unfortunately they've damaged trees by nicking their bark regularly and occasionally over-edge and take out the garden border plants. On the plus side they keep it all looking like a golf-course, don't mind putting away a forgotten sprinkler and hose, take care of the leaves in the fall.
In another buddies case he went with an old fashioned push mower when his gas one died. He says the effort is about the same, while the gas mower had powered wheels it took a lot of effort to maneuver so overall there was little effort change in the mowing. However he says it's a lot nicer following the snickity-snick of the mechanical then the roar, dust, and fumes of the gas one.
As to no-lawn - in some cases that's an option but in many it's not. There are often local laws about keeping up one's property and the hassle and ill-will of being different may not be worth it. Also the effort and cost of a more 'natural' look is often about the same as the green desert. Finally resale value of a house is greater with the traditional grass lawn then with other more eco-friendly or labor-saving alternatives.
Oh, and the old hire-a-kid? I tried that at my old house - none were interested. Nobody I know has any kids in their neighborhoods interested either. One acquaintance did tell a story of a new-to-the-neighborhood kid coming by asking but as his dad had just bought the house with the money from a large & very dubious job-injury claim the fellow declined.
I don't read ACs: If a post isn't worth so much as a nom de plume to its author then I wont bother either.
Why is an environmentalist spending money and gas to chop up happily growing natural plants instead of leaving them alone?
Come to think of it, why are you growing *grass* anyway? That isn't natural for most locales...

Nothing is zero emissions. It may not emit them right there but that battery gets charged somewhere and emissions are emitted there.
Why not replace the dead battery? That's what I did in my Black and Decker cordless electric. (In my case, I did have to crack the plastic body, since the bolts had rusted, but it was nothing duct tape couldn't fix.) A hell of a lot cheaper than a new mower, and more enviromentally benign than throwing the old one away.
I'm sure you could order a replacement battery from the manufacturer. It's the Right Thing To Do.

for specifics..
- We have a house with 1 acre backed against forest. Built in the 20's and newly remodeled. No homeowners assoc. (i.e. We refuse to live in a neighborhood with a name - usually hot and treeless, and the thing the neighborhood was named after isn't there anymore because they plowed it down to build the neighborhood) We have a small front yard kept nice to keep the neighbors happy - takes 12 minutes to mow. Landscaping, rocks, cobblestones, RR ties, grill, deck and pool around the house. Large treeless yard out back being converted to "attractive semi-wild" looking area - remove 90% of the grass there, leave paths etc.
I wasn't saying NO grass, I was saying having a large lawn is silly unless croquet is a priority. I don't know about kids these days (none of my own yet) but all through my childhood our yard sat empty while all the neighborhood kids and I were across the street playing in the 300 acre forest - which was infinitely more interesting than the vast green carpet behind the house.
"Having seen homes that have similar setups... they look awful when next to a decently-manicured lawn."
Beauty is in the eye of the beholder (just a random yard.. very cool site).
Operator, give me the number for 911!
My folks are retired, and bought a 50 acre farm.
They had about 15-20 goats to clear brush.
The things are seriously hard on fences because they lean on them to eat stuff outside.
Also, they prefer not to eat grass. They will, though, if hungry.
They do eat thorns, brush, grape plants, flowers, tree branches, small trees (1/4 inch around), etc,etc.
They eat just about anything green other than grass..
And they have to be shaved in the summer, housed in the winter, and watered..
And they BREED like crazy. segregate the herds (flocks?)
If I was going to by the iMow, it is obvious from reviews and such that while the mower may work, it works in a really crappy, non-intelligent manner. Just a random walk, with simple sensors. I would buy one of those, rip out the standard "electronics" (something tells me that the iMow doesn't really have a real computer in it), and replace them with a good micro-controller, add some good sensors (I think it only has a simple non-directional "bump" sensor - I would replace that with an array of bump sensors around the perimeter). Leave the wire, then add code the controller to tell it to go around the perimeter, measure the distance, then make another lap inside the first one (with a few inches of overlap). If obstacles are encountered, add code to go around the obstacle, but map it for later - the code would be similar to a generalised paint/fill algorithm...

Nice, grassless yard and yes, it probably takes waaaaaaay more maintenance than grass. I'm not saying it shouldn't be done, I'm just saying folks should be aware of what it really takes to "get back to nature."
;-)
In my area, I can and do grow most of what I saw - astilbe, hosta, ferns. And they take one very important resource - water, water, water. And your time to pull the "weeds." That nice lawn ain't just native stuff that came up after they rototilled.
It's well-manicured and well maintained. Someone - like my next door neighbor - spends a lot of time out there. Otherwise, you'd see nothing but bindweed and lawn ivy and that's not what's in those pics!
Good luck. I mean that. I'd like to have a lawn like that but I really only have time to mow!
Consigned to flames of woe.
For what it's worth, I'm trying the forest floor concept up close to my house under a HUGE cottonwood. Once I get through the first two seasons of weeds, I think I'll be okay.
I consider my house "new." I wanted to live in another neighborhood that was built in the 1880s. But I had to settle for this new, sparkly suburbia! Long story involving an urban-phobic spouse.
My house *is* going to be 100 years old in 15 years. Not bad. She's gettin' respectable, now.
And trees. After 80 or 90 years, the neighborhood actually has trees. Big ones. (And yuppies with leaf blowers, but that's another digression involving me, a rake, environmental concerns and building my upper body strength...)
Consigned to flames of woe.
If you put your cats out there just to be eaten by foxes, I don't think you're having much respect for the cats. Why don't you keep the cats indoors and let them eat whatever gets in, let the foxes have the mice which are still outdoors, and never the twain shall meet?

One point that no one has picked up on yet is the fact that the iMow takes 10 times longer to mow the same patch of land as a human-controlled mower. This means it takes 10 times more power and thus would probably cause more emissions than even a normal gas mower. I got a Black and Decker CMM1000; it works quite well and appeases the environmentalist in me.

I have a Friendly Robots model, which is the same as the iMow. I have used is for a few years now and find it very useful in the open back lawn. It is a few feet long and so does not work well in the narrow strip between the houses. In automatic mode it's safty software turns it off on hills greater than 15 degrees, but I can use the game pad like control to manually drive it and have set the wire to have it avoid the hill. I leave it out many Saturdays or at night and go shopping or make dinner and it is done when I return.
It's more a 80% solution, a way to reduce the work than a complete solutions, your will still need a edge trimmer. I normally in a wet summer put it out every few days and run the normally mower over the edges and strip between the house every two weeks. There are some OS bugs in the firmware, but I think the product is generally good and I recommend it.
It is very safe with lots of sensors safty features and warning lights. The quality of cut is very nice.

Is a good link for this, since it is from a group that is actually trying to portray lawnmowers as clean. However, look closely at their numbers:
According to them, a walk-behind mower is used an average of 25 hours per year, and a car is driven an average of 14,000 miles per year.
In two years, the mower produces 2.1lbs. of emissions, and the car produces 20lbs. They go on to claim that this means mowers are cleaner, but the difference in amount of time in use in their example is staggering. At an average of 50mph, a car driven 14,000 miles per year is in use for 280 hours, compared to the measly 25 the mower is used.
280 hrs. / 25 hrs. = 11.2
2.1lbs. * 11.2 = 23.52lbs.
So a lawnmower is producing more emissions per hour of usage THAN A FREAKING CAR, according to the stats given by the OPEI, an obviously pro-lawnmower group.
A friend of mine has a IMow. It's cute to watch but takes a long time. His lawn at about 2000 square feet is about half the size of mine. His IMow took almost three hours to do the job. He still had to manually hit a few spots it missed.
My non-self propelled gas mower takes me about 25 minutes. Plus I get a little exercise to boot.
