Just drive the Robomow to the edge of your yard and press 'Go' for a beautifully manicured lawn.Robomow RL850 At a Glance:Automatic lawnmower mows entirely by itselfCuts up to 10,800 square feet in a single chargeOn-board sensor and bumpers to avoid obstaclesGrasscycles for a healthier, greener lawn that requires less waterQuiet operation means you can mow day or night Robomow does all the work so you don't have to.Operates without gas, oil, or spark plugs.Automatic Lawnmower Does All the Work for YouThe Robomow RL850 is an innovative lawn mower that works automatically, so you won't have to spend another weekend pushing your old gas guzzler around the yard. It mows on its own within a boundary that you outline with a thin wire (included). Once you handle the initial wire setup, this mower does all the work for you--simply press 'Go', sit back, relax, and mow!Powered by exclusive drop-and-go 24-volt batteries, the heavy-duty Robomow RL850 is an eco-friendly 53-centimeter, 21-inch mower/mulching system. With its three blades spinning at 5,800 RPM--double the speed of a typical gas mower--the Robomow RL850 travels across your lawn in a crisscross pattern, covering up to 10,800 square feet on a single charge. Easy to set, the Robomow RL850 delivers a 1.75- to 3.25-inch cut with high-cut blades and a 1.0-2.5-inch cut with low-cut blades. Eco-Friendly, Wallet-Friendly ChoiceUnlike conventional lawn mowers that pollute as much as 40 late-model cars in just one hour of use, Robomow RL850 offers a way to keep your lawn looking great without sacrificing the environment.The Robomow RL850 doesn't simply cut your grass--it repurposes the clippings through a patented process called grasscycling. The mower cuts grass into fine clippings and disperses the cuttings over the ground. These clippings quickly decompose and release valuable nutrients and water into the soil, resulting in a better-looking lawn. Grasscycling also leads to a deeper, healthier root system that increases your lawn's resistance to disease, drought, and insects, and it reduces the amount of water your lawn needs by as much as 85%.And because the eco-friendly Robomow RL850 doesn't require gas, oil, tune-ups, or spark plugs, it will save you money. Multiple Features for Safe, Quiet OperationIn addition to its environmental benefits, the Robomow RL850 offers several user-friendly, neighbor-friendly features. First, a user-controlled theft protection system guards the mower from unauthorized use, and a child lock provides peace of mind. An on-board sensor and bumpers identify obstructions like trees, rocks and obstacles, and truly quiet operation means you can mow your lawn at any hour without disturbing your neighbors.Dimensions and Warranty InformationThe Robomow RL850 is WEEE and RoHS compliant, measures 26.0 x 12.5 x 35.0 (WxHxD), weighs 50 pounds (without battery), and is backed by a two-year warranty.What's in the BoxRobomow RL850; 500-foot perimeter wire and 200 plastic pegs; sealed batteries and charge pack; 2007 Generation software; instruction manual.

By Golly, It Works

by KMW from NH on 2004-05-21
My paid lawn care service bailed out on me and left me high and dry with no mower and a lawn that was beginning to look like a hayfield. I added up the money I paid others to mow my lawn last year, and decided that if the Robomower worked, and lasted 1-1/2 years, I'd be even, and wouldn't have to give up my evenings after work and brave the mosquitoes and black flies. I love it. I'm stretching its capabilities in terms of lawn size and inclines, but the little thing just keeps chugging along. I have it set to high clearance and a high cut, and it is handling my very uneven lawn with no problems. It took two mows per zone to transform my badly overgrown lot into a groomed lawn. The cut is good, just like my riding-mower or push-mower neighbors' except without the lines. The Robomower mulches beautifully, leaving no evidence of clippings on top of the grass. I start the mower when I get home from work. While it mows, I'm inside doing all the other evening chores, and then relaxing. It keeps on mowing after the sun goes down, and it's so quiet that you won't disturb the neighbors if it finishes up at 10 PM. (Just remember to bring a flashlight to find where it has stopped when it is time to bring it in!) While you can just set it up and go, to get the best cut be prepared to spend a little time optimizing things after you've seen it run a couple times: adjusting the perimeter wire, and changing zone configurations if you need to. I started out with two zones, but changed to three, given the size(10,000 sq ft+) and irregular shape of my lawn. I may get the optional fast charger so I can mow more than one zone per day. Side effect: You will get passers-by stopping to stare and chat. It is a definite conversation starter. Added over two years later: Still working, and I'm still happy with it.

Does exactly what I expected, and does it well

Love it. I bought this mower at the start of last summer, calculating that if it lasted a year and a half or more, I'd break even on what I was paying a lawn service to mow my yard. I have an fairly uneven yard, with some steep parts. Set to the highest mow, robomower easily navigates the rough spots, and manages the slopes well. Robomower takes a lot longer to mow a lawn than it would take you to do it manually, but since you are off doing something else, and robomower can work in the dark, that doesn't matter at all. Be prepared to experiment with the perimeter wire. I found dividing my front, side, and back yard into three zones was the best choice for me. Do the final complete pegging after you've run the mower a few times and know the wire is in the right place. If you have multiple zones and live in a part of the country where mowing days are limited by frequent rain, get an extra battery and/or the fast charger, so you can mow more than one zone per day when you get the chance. The mowing pattern is not up and down in lines, but in angled criss-crossing, leaving lots of gaps at first, so you won't see a clean mow until it's done. But when it is, the cut is very nice: a smooth buzz cut with no lines, mulched finely leaving no clumps. My neighbor, who bought a riding mower just before he saw my robomower, agrees. After watching it all summer, he came over to say, "This thing does a really nice job. And you don't have to be outside with the mosquitos...." So, now, when I get home from work on a dry day, I put the mower out in the next zone that needs done, and go in and let my cats out. Later in the evening, I go out and fetch the mower and let the cats in. My lawn gets regularly mowed and has never looked better.

Works great! Wire placement takes time.

Look, this took me 2 hours to write and edit just right because I'm passionate about my robotic lawnmower so give me the courtesy of reading this in full and then decide for yourself. I live in Florida and can handle edging and blowing, but not mowing. I have about 1/4 acre of grass and my property is an L shaped corner lot. Why did I buy a Robomower rather than hiring a service? This was a no brainer decision. Pay $140 per month to have someone MowBoe mow my lawn no matter what month of the year it is (quick math $1680/year), OR.. pay about $1000 and have Wilson mow the lawn more often and be rid of the deafening noise of the lawn service's equipment. PLUS SAVE MONEY! How much of a savings? In my case about $2000 in two years. If this mower lasts 2 years it has paid for itself two times over, but from what I read, this bot lasts much longer. The longer it lasts, the more money I save. I considered the 1000 series, but my lawn's area isn't that large and the docking station doesn't really make things exciting for me. Wilson is my Robomower. Yes, I named it, I admit it. I name robots, it's tradition.... or it will be in a few decades. I also have a Roomba SAGE called Rosie and a Roomba Scooba called Willie. Robots are the way to go, even though they are really god awful stupid.... for now anyway. I read all the reviews I could find on the RL850. Generally speaking they gave it two thumbs up except for the on board settings. I read the manual 2 times because I don't have a life and I didn't find anything too difficult to understand about the settings. If you can program your answering machine, you can do this. HOW IT WORKS There are 2 main settings you decide for the robot. The first one is follow the wire loop you laid down first then mow inside of it, this setting is called (EDGE), normally it would skip the edge so you have to tell it. It's just a push of 2 buttons. There is a second separate feature you can set called (WIDE SCAN), this allows the mower to take longer passes before it decides to turn to another compass heading. This should be set after watching the robot mow your lawn a few times. It's for efficiency, you really don't need to do this if you don't have the time.. but like I said.. I don't have a life so I don't mind looking out of my window watching my mower do it's thing for an hour or two. Oh yeah, I'm the talk of the neighborhood alright. Yup, there's that crazy guy watching his robots again. Basically, the Wilson unit has a built in compass and knows the direction it is cutting (for example North to South). Wilson cuts in a tight zig zag fashion meaning it moves south until it hits an obstacle or detects the wire then moves a little to the right and moves north. Back and forth it goes, at some point, Wilson decides to change the direction of the cut. There will be uncut globs here and there, don't worry, somehow the idiot programming runs over these spots and your lawn will look perfectly mowed as if someone did it with a precision shaver. Yes, it's that good. It's like a barber cut my lawn, just keep those blades sharp. By the way, it handles small branches very well. Remember, you MUST lay down the wire first. The bot will look for a signal from the wire or it won't turn on. A nice safety feature. LAYING DOWN THE WIRE Depending on the layout of your lawn, it may take you a few hours as the manual suggests, but my L shaped lot with a white picket fence smack in between and a detached garage has taken 3 days of planning, experimentation and installation. 3 zones have been laid out. Nevertheless, if you have a less complex lawn configuration than mine, such as a big square you should be done quicker. For multiple zones, I suggest you lay out only one zone first. ONE ZONE! Then try the bot out to see how it handles the layout. This will help you make adjustments and better layout decisions for the other zones. This may take more time at first but it's better than pulling up stakes and readjusting. That can get very messy. Burying the wire 3 to 6 inches in the ground is not a problem for the mower. I have it going under my brick paved walkway. No problems with navigation. You don't need to bury the wire, just clear the way for the wire with an edger, wet the ground, then lay the wire on top of the grass and brush your hand over the grass so it hides in between the grassblades. Over time, the grass will grow over the wire. The wire must be laid out in a big loop around your lawn then meeting back to a simple transmitter coupling. Don't rely on a fence to be a perimiter for you. Robomower will not do a good job bumping in to many things because it shuts the blades off, backs off then turns the blades on after it moves which is another safety feature I like. If you have trees it's ok to have it bump the tree, but bushes or flower beds must have the perimiter wire around them. SUGGESTIONS PLAN AHEAD! MEASURE! Make sure you have enough wire. The RL 850 box contains 4 bags of 50 stakes each. Plan to punch a stake every 3 feet or so. They give you 500 feet of wire which is good for 4 bags of stakes. If you need more wire buy it but don't cheap out on the stakes. I've caught Wilson's front wheel snagging the wire and pulling on it because I tried to cheap out on the stakes and used less than I should. Of course if you bury the wire this will not be a problem. Remember, I am saving at least $500 for the first year and over $1500 fore every year afterwards having Wilson doing my lawn with very little elbow grease of my own. I want the wire to be there permanently without any snags so It's dumb to cheap out on the installation. WHY ELECTRIC OVER GAS I had it up to here with gas engines! I've given up on them which is why I contemplated a lawn service. Oh, they start up right away at first, but then it's maintenance time and cramps from pulling and tugging on that start rope. I threw out more sweat trying to start the darn things than to actually mow! Then it's the oil, the expensive fuel, yada yada yada... Electric motors have more torque than gas motors and are QUIET!!! Wilson was so quiet, I went and purchased a Black and Decker 18v cordless edger and a Black and Decker 18v cordless blower and gave away my gas engine edger and blower. Now I can edge my lawn at midnight and my neighbors won't even know it. Try that with a pull push tug skanky gas hog that breaks down and not to mention gets VERY HOT! A riding mower doesn't do it for me. I look like a weeble in the first place and will make my neighbors laugh. Also, the noise, the gas, and I still have to edge and blow. PLUS! The riding mower is MORE EXPENSIVE! And I have to store it! Wilson fits under a shelf in my garage. It takes less space than a walk behind mower. Do the math. HAVE DOGS? I have two Shepherds. Beautiful, courageous and strong. Besides giving everyone a second thought before coming close to the house, they have one genetic quark. After a good dump they like to wipe their bear claws in the lawn, tearing in to it. This airates the ground somewhat so it's good, but take this in to consideration when you are laying down wire. My male shepherd I call Monster already ripped up a wire without knowing. He's a good boy, so now I have to make sure he doesn't do his business by the edge of the fence. This is a training period for both man, animal and robot. Lawn... the primal fronteer... the everending saga of man over veggie and the pursuit of perfection. The Lawn Weeble

LOVE IT!

Looks like a lot of the reviews that are negative talk about RoboMowers they've owned for at least two years. That would mean they're usually talking about the old models, the RL500 or 550. (Lots of upgrades since then for the "getting stuck" issues, but I cannot speak to the reliability yet.) My review is for the RL850, which is listed here. This mower does exactly what they say it will do. I have had absolutely NO problems whatsoever. My front yard has a pretty steep slope, which causes no trouble at all. My back yard has a crabgrass problem, also no trouble for the RoboMower. I set it out, it does it's thing. When it's finished I spend about 5 minutes getting a couple of narrow points that the RoboMower can't reach, and I'm done. My boyfriend who likes to mow (I've always hated it) says I've spoiled him now that he's seen the "finer things" and wants to setup his own yard to use it! The grass looks great when it's finished, no raking as the pieces of grass are chopped very finely. I would buy it again in a minute.

I just purchased my RL 850 from Amazon and installed the wire last weekend. I gave my lawn it's first Robo-cut. The lawn looks like it got one of those professional haircuts. Looks like a golf course. No visible tire tracks anywhere. It did take me 4-5 hours to stake the wire and adjust the edges by myself - and that was only the back yard (roughly 100'x75' with one landscaped island). It took approximately 2 to 2-1/2 hours to mow a lawn I can cut in 45 mins. But I managed to get a nice sun tan on my lounge chair while IT was working. If not for the picnic table obstructing the path of the Robomower, it would have done the job all by itself. I had to modifiy its course to finish cutting an area the table kept blocking it from. And it did get hung-up once backing up onto some tree roots (lifted off the ground and didn't make contact - wheels kept spinning). I have a few trees it just bumped into and backed away from. So I guess I can't let Robo do it's thing unattended - at least not yet - and the instructions tell you NEVER to do that anyway). As I develop more trust in the mower, I'll probably get some other chores done while it does the back yard (if I can tear myself away from watching the silly thing doing its job - looks like a turtle). I'm considering purchasing more wire and perimeter switch for the front yard - but crossing over the sidewalk and driveway seems a bit complicated and perhaps hazardous (blades over concrete). Now I need a clever name for it. Any suggestions? Highly recommended product for those who have better things to do than walk up and down - back and forth - across their lawns - once or twice a week. Get it on sale tho! Turbo Tony Robomower and Roomba vacuum - anyone invent the home car washing robot yet? Updated Nov 6, 2007: I just finished my first season with the RL850 Robomower. What a delight! The minor problem I had with it getting stuck on large tree roots - fixed by pounding a few stakes next to the roots. "Bobby" delivers a near perfect cut each time. It does miss a very small patch or two every now and then - but so what - it gets it the next time. The only regret was spending the money to buy this thing so that I could get more leisure time - but as it turned out - my 16 yr old son is the one who got the extra time off! Now he only cuts the smaller front and side grass with the noisy old Toro. Did I mention NOISY? I really got used to the "sounds of silence", well, ok, sounds of humming - while Bobby cut the lawn. It's to the point where I throw mean looks at my neighbor every time he cuts his lawn with his loud gas mower while Im trying to lay-out back and catch a few rays. If only everyone ( or at least both of my neighbors ) had one of these. Consider this an endorsement. The thing works. And it's good for the environment ( can I use it as a tax write-off ? hmmmmmm..... ) Updated August 24th, 2008: "Bobby" is nearing the end of his second season of mowing my lawn (got maybe 1-2 months left). It's performing like new. I charged the battery last Winter per online advice - remove the battery from the mower and charge for 24 hours once a month. It still runs for over 3 hours in it's second season. Love the cut and my wife says I'm getting lazier every day. Gotta love it! Thinking about buying more wire and another perimeter switch for the front yard (probably only 1/2 the front since my driveway splits the lawn). Tony
