This is the robotic lawnmower that landscapes autonomously without any programming. Operating similar to household robot vacuum cleaners, the Worx Landroid lawnmower cuts grass in a straight line and changes directions when it reaches an obstruction or virtual wall. Its sophisticated intelligent design enables the robot to generate random cut patterns, navigate narrow passages, and remember up to four outdoor areas. Its 7"-diam. blade adjusts to cut at five different heights (from .75" to 4") and rotates at 2,800 rpm, mowing and mulching as it circumnavigates a yard. A hidden wire (included) provides invisible boundary lines for forming a perimeter of the yard, to ensure the lawnmower will not stray. The robot returns to its docking station when it has completed cutting the lawn, needs to be recharged, or detects ambient moisture/rainfall. It automatically shuts off when lifted in the air, and the mower’s user-friendly control panel enables one to set an automatic mowing schedule. Includes nine replacement blades, 590' of above ground/underground boundary wire, and installation pegs. A 90-minute charge provides enough power to mow 1/4 acre. Charging base plugs into AC with included adapter. Wire yard boundary requires minor assembly. Not available for shipment to California. 26" L x 21" W x 13 1/4" D. (44 lbs.)
