Product overview

Lawn care can be so easy and effortless! With its CorridorCut Systems, the GARDENA SILENO Life 750 mows your lawn accurately and reliably and delivers a clean cutting profile. You can enjoy both your free time and a perfectly manicured lawn.

The SILENO Life 750 robotic lawn mower from GARDENA is designed for lawn areas up to 750 square metres, and delivers a beautiful, cleanly mowed lawn without the need for a catcher.
Discover a robot mower that takes care of your lawn reliably, evenly and quietly. It is easy to install and program, runs on a Li-Ion battery and automatically returns to its charging station when recharging is required. Like all GARDENA lawn robots, the SILENO Life 750 is extremely quiet - its 58 dB(A) is unrivalled. You won’t have to worry about disturbing the neighbours, they won’t hear a thing! The three small pivoting razor blades finely clip grass and these fine cuttings act as mulch and a natural fertiliser. This promotes good growth and saves valuable time and energy on disposal.

It is also all-weather. Rain is no problem as SILENO Life 750 continues mowing, keeping your lawns at their beautiful best all year round, and on lawn slopes of up to 35% (19 degrees). In cool weather, the Frost Sensor protects your lawn by detecting when the temperature is close to the freezing point and stopping mowing accordingly.

The CorridorCut function is specially designed to cut the lawn in narrow areas from 60cm wide, tight corners and even dead ends with reliable precision. Thanks to the SensorControl function, the SILENO Life 750 can measure grass growth and efficiently adjust mowing times accordingly. And when it needs a clean, the underside can be easily washed with your garden hose.

Setting up SILENO Life 750 is straightforward, and everything you need comes in the box. Designate the area to be mown as described in the instructions with the boundary wire and orientate SILENO Life on the lawn with the guide wire. Programming can be set either using the GARDENA Bluetooth® app (up to 10 metres away) or directly on the user interface on the machine itself. Either way, it has easy-to-follow instructions and during the simple installation process, a programming assistant guides you through the menu and self-calculates the mowing plan. The mowing times can also be freely programmed.

After the initial installation and programming, the SILENO Life 750 continues to automatically and independently mow the lawn within its mowing programme. And you can adjust the programme to best suit your lawn and conditions at any time.

Love it, time saving

It's great for the price. You need to setup the wire correctly but after that everything is perfect and no issue.

Gardena Robotic Lawnmower

Followed the instructions and using the "wizard program", the robot has been working as described for two weeks. It is important to get the boundary wires exactly right, or you will get some hairy edges. I have had to relay them in several areas! The end result is pretty good, though I miss the stripes from the old mower! One more job I do not have to do!
