The RL850 is the new RL series RoboMower for 2004. Similar to the RL800, but packed with new features and options for every user. The RL850 offers an upgraded software version of the RL800, improving even more on the power management system, for greater efficiency and coverage. The RL850 also includes hardware improvements, weather protection improvements and gear train improvements for greater durability and long life. Best of all, the RL850 is designed for upgradeability to a docking system. For the user not sure if a docking system is right for them, the RL850 is the best choice. You can convert the RL850 to a docking system mower at any time after purchase.
RoboMower is operated by pressing the green button on the unit. It travels on the lawn in a systematic chris-cross pattern covering the lawn several times from side to side to ensure that the entire yard is covered and the grass is cut from several angles.
RoboMower is provided with an integral manual controller that is used to drive the unit from the storage area to the lawn before operation and back to storage after operation. The manual controller also allows the user to use RoboMower as a manual mower in order to cut areas of the grass that could not be reached in the automatic operation if necessary. While in storage, the unit is connected to a charger in order to recharge the battery. Recharging typically takes 24 hours, so the RoboMower is ready to run the next day. Typically, however, customers run the unit as often as they used to cut their grass with a conventional mower, i.e. once or twice per week.
