How do I start and stop the GARDENA Robotic Lawnmower?

Once the system is installed you can easily start the mower by pressing Start and close the hatch. To stop it, simply press the red STOP button.


Do I need to bury the wire in the ground?

No. The wire can be laid upon the ground using the supplied pegs and will after some weeks be grown over and disappear into the grass. A good tip is to cut the grass as short as possible at the perimeter in order to get the wire as close as possible to the ground. However, to allow for aerating of your lawn, you can bury the wire up to 5-20 cm deep.


How do I adjust the cutting height?

It is very easy to adjust the cutting height. Open the hatch and turn the height adjustment knob. You can choose a height between 2-5 cm


How long does it take to recharge the batteries?

The robotic mower automatically returns to the charging station and charge for approximately 45-90 minutes depending on model. After completed charging the mower automatically starts cutting.

Approximate charging time per model:
- Gardena R80Li 60-90 minutes


How long does it take to mow the lawn?

The principle of a robotic lawnmower is to continuously cut the lawn so that it will always be well maintained and have a good looking. The question “How long time it takes to mow the lawn” is therefore not applicable on a robotic mower.


How does the GARDENA Robotic Lawnmower work and how does it know where to go?

The working area is defined by a perimeter wire (called loop wire) that you can compare with the fence for sheep. The robotic lawnmower operates in a random pattern within the fence. That gives a carpet-like nice looking result.


What happpens if the Robotic Lawnmower hits trees or other objects?

The GARDENA Robotic Lawnmower will make a gentle touch to the tree, reverse and change direction. Soft/sensitive obstacles and obstacles lower than 15 cm are simply protected by laying the loop wire around that obstacle. That will make the mower stop and reverse without touching the obstacle.


How much grass won’t be cut?

The amount of uncut grass depends on how close the edge of the grass the loop wire can be laid and which model of the robotic mower you have. See below illustrations.

  • 5 cm from the edge gives no uncut grass.
  • 20 cm from the edge gives gives approx 12 cm uncut grass.
  • 30 cm from the edge gives approx 20 cm uncut grass.

Note that the amount of uncut grass can be reduced or even eliminated with some rearrangement of your garden, for example by replacing the outer part of the lawn with flat stones or concrete.


Do I need to collect grass?

No. The principle of continuously cutting makes the clippings become very small. These clippings fall to the ground and fertilize the lawn.


How can I program the GARDENA Robotic Lawnmower timewise?

Use the timer settings to make the operation time suit you and your garden. For each 30 m² lawn area, please program one hour of operation time per day. Example: For a lawn of 300 m², from 7.00 until 17.00 or from 7.00 until 12.00 and again from 15.00 until 20.00 (all days a week). During that operation time, the Robotic Lawnmower will independently mow and charge. You can also increase the time per day and skip cutting one day per week. You will find more examples on how to set the timer in the operator's manual.
