The Ambrogio 4.0 Basic Premium robot is the robotic mower for large 2/3 acre lots. It mows up to19,300 sq ft of grass, not including the house, driveway, etc., which is just under 1/2 acre.

If your lot is more than 0.6 acres, take a look at the L210 Elite or the L250i Elite. If you have a lot larger than 0.8 acres, check out the L250i Elite S+ or the 350i Elite. Or, consider two 4.0 Elite robots configured with the Infinity System for double the capacity!

The key features of Ambrogio 4.0 Basic include:

1. Jointed body
2. Wide rubber tires
3. Control via Smartphone app, including the ability to steer the robot
4. Durable & robust build quality. Quality is identical to 4.0 Elite.

The most unique feature of Ambrogio 4.0 robots is the jointed body that allows the robot to conform to the shape of the ground. The joint is between the deck and the drive wheels. It tilts side-to-side, preventing scalping of the grass on uneven terrain.

The Ambrogio 4.0 Basic Light,  Ambrogio 4.0 Basic Medium, and the Ambrogio 4.0 Basic Premium  are identical robots except for their power units. The chart on the Ambrogio 4.0 Basic model page indicates the lawn areas, battery size and typical working times for each power unit size.

Choose the power unit appropriate for your yard size and budget. You can always choose more mowing capacity for a smaller lawn. The advantages are: 1) faster completion if the robot is paused and 2) longer battery life time due to battery not being fully depleted each time the robot runs. Choose a larger-capacity power unit if your grass is dense and if you have many trees, flowerbeds or obstacles vs wide open areas.

All Ambrogio 4.0 models are fully autonomous and recharge themselves.  And, they are Bluetooth-enabled and remote-communication-capable (Basic model requires option purchase). They can be steered and programmed from a smartphone in close proximity. Remote communication enables a sub-set of commands to be sent from anywhere, such as "Work for a Time" or "Return to Station".
