Smart features & benefits

From compact models for small spaces to advanced units for complex lawns, there’s a robotic lawnmower to suit every backyard. Enjoy the benefits of time-saving automation, a consistently well-maintained lawn, and safe, weather-ready performance.

All robotic lawnmowers feature auto-dock charging, meaning your mower automatically returns to its charging station when the battery runs low. A built-in frost sensor detects temperatures close to freezing, pausing mowing to protect your lawn’s health during cold conditions.

With a low noise level, these wireless robot mowers quietly maintain a beautiful lawn without disturbing your family or neighbours. Gardena automatic lawnmowers are eco-friendly, fully electric, and require minimal effort. No fuel, no emissions, and no hard work involved.

Installation & care tips for automatic lawn mowers

Setting up your robotic lawn mower is straightforward. See the user manual on product pages for more information.

Start by laying the boundary wire around your lawn’s perimeter. Place the charging dock on a flat surface in a convenient location. Then, program the mowing schedule via the GARDENA Bluetooth® app or directly on the machine’s user interface. The built-in programming assistant guides you through the menu and self-calculates a precise mowing plan for total convenience.

Keep your robotic lawn mower in top condition by cleaning the blades and wheels regularly to prevent grass build-up. Replace blades seasonally for a consistently neat cut. During winter, store your robot lawn mower indoors in a dry location to protect the electronics.

Frequently asked questions

How does a robot lawn mower work?

A robot lawn mower uses smart sensors and boundary wires to navigate your garden, automatically mowing at scheduled times. It detects obstacles, avoids edges, and mulches grass clippings, which can serve as natural fertiliser. When low on battery, the robot lawn mower returns to its charging station to recharge itself.

Can robotic mowers handle sloped or uneven lawns?

Yes, Gardena self-mowing lawn mowers are engineered to manage slopes up to 35% (19°), depending on the model. Their advanced sensors and swivelling rear wheel ensure stability and smooth navigation across complex landscapes.

Are robot lawn mowers safe for kids and pets?

For safety, you should avoid using a robot lawn mower around children or animals. If a child or pet is on the lawn, use the park mode to ensure the robotic lawnmower is off. Gardena recommends scheduling the robot mower to operate when the lawn is free from activity.

How long does it take to set up a robot lawn mower?

Setting up a robotic lawn mower typically takes a few hours, depending on your lawn’s size and layout. You’ll install the boundary wire and stakes, clear debris, and configure the robotic lawn mower through its app or user interface.

Do robot mowers work in wet weather?

Yes, Gardena robotic mowers are designed to perform efficiently in various conditions, including light rain.

What maintenance do robot lawn mowers need?

Robot lawn mowers require minimal maintenance. Regularly clean the mower’s blades and underside to remove grass build-up, check the wheels for debris, and occasionally replace the blades for best results. Keep the charging station area clear and update the software when prompted through the app.
