Automatic Lawnmower Does All the Work for You
The 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 a 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.
Wallet-Friendly Choice
Unlike 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 Robomow RL850 doesn't require gas, oil, tune-ups, or spark plugs, it will save you money.
Multiple Features for Safe, Quiet Operation
In 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 Information
The 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.

The Friendly Robotics RoboMower Automatic Lawn Mower is a fully automatic lawnmower designed to mow your lawn entirely by itself. The fully-automatic mower travels across the lawn in a crisscross pattern, covering up to 10,800 square feet on a single charge while you relax on the porch. The RoboMower works by mowing within a selected boundary outlined by a small wire (the unit includes 500-foot perimeter wire). Its navigation system can handle any lawn, regardless of shape, slope, or obstacles. It is capable of mowing 3/4 of an acre on one battery charge. Because the mower is rechargeable, it doesn't need gas or oil, and emits no pollution and little noise. However, it's still as powerful as conventional mowers, employing a battery-powered 3-blade, 21-inch powerful cutting system equivalent to a 5-1/2 HP gas mower, but with better mulching and a 5,800 rpm blade speed (double that of a typical gas unit).
The Triple Chamber Mulching system compacts grass into small clippings that decompose naturally on the lawn, improving your lawn's health while lightening your workload. The mower also comes with a host of safety features, such as a child lock and a detection system that automatically turns off the blade if the mower is lifted. It also includes a user-controlled theft protection and disabling system using a personal password. The mower comes with plenty of oomph, completing about three hours of mowing with a single 24-hour charge. The RL850 is also upgradeable to the RL1000, which comes with a programmable docking station. The RL1000 will automatically depart and return to the docking station at preset times to mow the lawn--even at night while you're sleeping--adding yet another level of convenient operation. A 2-year warranty is included and comes complete with 2007 generation software.
