Differential GPS

the system allows the robot to cover large areas without the need for a perimeter wire, with centimetre-level cutting precision. The robot can move autonomously by remembering the areas that have already been mowed

Cutting System "Prederminated Path"

a map can be defined at the time of installation which allows the robot to generate paths and parallel lines to cover the mowing area in the shortest time possible

High efficiency brushless motors

wheels and blade brushless motors not only have a longer life-span and need less maintenance than ordinary motors. They also feature lower noise-levels, and lower energy-consumption

Carbon housing

lightweight and robust carbon casing

Eco Mode

to detect the lawn that has already been mowed and reduce the working hours for the benefit of the lawn and robot

Bluetooth receiver

to transfer software updates from Smartphone/Tablet to the robot and to use the “Ambrogio Remote” App from IOS and Android

Touchscreen remote control

the tablet supplied with the robot comes with a Motion Control system that allows the operator to guide the robot with a simple hand movement

SMS Alert

daily report with any error messages

Spiral cut

in case of higher and/or thicker grass in an area of the garden, the robot automatically activates the spiral movement for a perfect finish

Push & Stop button

the button positioned on the housing allows stopping the robot and blade at any time

Manage up to 4 areas

allows 4 different areas to be cut. You define which and how much. The robot reaches the area by itself – through narrow passages, along driveways and by crossing yards. It also self-programs the work according to the specific area

84 cm blade

three star-shaped blades (4 edges) in stainless steel that provide a total mowing width of 84 cm. Two out of three are arranged on pivoting arms that allow you to mow even on uneven surfaces
