Why the SILENO flex Mower?
Why Boundary Wires
Robotic mowers that use satellite positioning have expensive components and are prone to signal disruptions. Robotic mowers that use boundary wires require a little more effort up-front. However, they tend to be much less expensive and provide a more consistent, precise cut.
The SILENO flex uses boundary wires. This way we can provide a very precise cut at an affordable price; and we have been selling reliable boundary-wire mowers for over a decade.
Advanced Mowing Precision
Define your mowing area precisely with the included boundary wire, allowing for millimeter accuracy around garden beds, pavement, lawn edges, and other obstacles. The included guide wire supports the installation of one or two wires, depending on the layout of your yard. The technology provides up to five remote start points for full coverage, aids the mower in navigating narrow corridors or reaching remote areas of the lawn, and guarantees a consistent and even cut throughout your entire yard.
Easy App Control
Remotely connect to your SILENO flex from up to 33-ft away and experience the convenience of managing your SILENO flex mower via the GARDENA Bluetooth® App*. The clever Scheduling Assistant guides you step-by-step to the optimal mowing schedule based on location and grass type, while the home screen provides accurate and updated information on the status of your robotic mower.
Simplify your mowing experience
Our mower features an easy-to-use control panel with an intuitive user interface design. The height adjustment knob allows you to effortlessly adjust the cutting height, ensuring precision for both high and low cuts. In addition, convenient push buttons provide quick access to key mower functions.
